People You Will Need When You Already Have A CNC
People You Will Need When You Already Have A CNC Machine
If you think that you will just sit back and relax when you have a CNC machine in your shop, think again. CNC may help you speed up your operations and even make them more efficient. However, CNC is not a wonder robot which will make you disregard all your employees and expect your shop to run on auto-pilot.
Though you will need more people without the CNC technology, you will need only three very, very skilled people. Call these people your friends, your team, whatever. In the long run, they might be just all you need to keep the shop in good shape.
THE PROGRAMMER
The first person is the CNC programmer. S/he is like the “playmaker”. S/he will create the programs that the CNC machines are intended to execute. Since the programs are in the form of CNC codes fabricated like sentences, he should have mastered these codes because they work like a different language. The regular CNC machine can use up to 50 codes, so thats like learning 50 new words for the newbie.
Also, the programmer should have at least and engineering or machining degree. Remember that the CNC machine will only execute WHAT IT IS PROGRAMMED TO DO. If the program is wrong, the whole operation goes down the drain with it. Moreover,s/he should also be flexible and have a fast turn-around because a CNC machine is often used to machine a huge selection of different work-pieces.
THE OPERATOR
The second person that you need is the CNC operator. S/he will simply recheck the programs loaded to the machine and push the right buttons to get the work done. However, thinking that a CNC operator can have little or NO SKILL AT ALL is wrong. A CNC machine operator must have at least basic machining skills and s/he should have undergone some form of training to run a CNC machine.
These machines can produce very intricate motions, making it possible to make shapes that cannot be created on conventional machine tools. So, the operator should foresee this complexity and know how to cruise with it. The skills that an operator must have though, are lesser compared to the operators of conventional machine tools.
THE TECHNICIAN
The third person that will need is the CNC technician. Although this may still be the programmer, its more convenient to always have a technical expert on-call because in the long run, you may have more than one CNC machine and you may need to prioritize over the other in case both gets crippled at the same time. Just like the programmer, the technician should also be flexible and articulate. CNC offers a lot of complexity when its running right, how much more if its behaving badly?
So, if you are having job openings for positions that need to be handling a CNC machine, ask the applicants first to do a demo for you and make sure that during the demo, they know what theyre doing. An exam may also do wonders too. If they have no experience with any kind of CNC machine, it is advisable that you encourage them to take short courses on CNC.
Eighty-hour courses are available online and hey, its better than nothing. Experts even encourage employers to hire CNC machinists who have finished AND PASSED the National Occupational Competency Testing Institute (NOCTI) assessment just so they could be sure that their CNC machines will go to good hands. After all, a CNC machine is still an asset.

Pad Printing with CNC
Pad printing is a process where a 2-D object is transferred into a 3-D object. It is done by using an indirect offset printing process that involves an image being transferred from the printing plate via silicone pad over a surface that is to be printed.
Pad printing is used on a lot of industries that includes medical, automotive, promotional, apparel, electronics, appliances, sport equipment and toys. Pads are three dimensional objects typically molded of silicone rubber. They function as a transfer vehicle that picks up ink from the printing plate, and then transferring to the thing to be printed upon.
Examples of pad printing are the printing of labels on the keys on a keyboard or the logo of a toy manufacturer on a Frisbee. The unique properties of a silicone pad allow it to pick the image up in a variety of surfaces such as a flat, cylindrical, spherical, compound angle, textures, concave surfaces or a convex surface.
In presses that uses pad printing with Computer Numeric Control (CNC), the substrate or a material that can be printed on, such as paper, film, plastic, fabric, cellophane, or steel, is stationary and the silicone pads are programmed to print one image at a time.
With a press that uses Computer Numeric Control, the substrate is stationary and the pads are all programmed to one image at a time to achieve a multicolor print.
Though the robotic actions of these presses that uses Computer Numeric Control seems rather complicated, it allows simple setting procedures that enable several programs to be inputted into the machine. All actions are controlled by servo-motor drives giving a very smooth and highly controllable printing action, also giving stroke lengths to be infinitely variable to the dimensions of the machine. Manufacturers even claim that using presses with pad printing capability that uses Computer Numeric Control gives considerable energy savings to the industry.
The Computer Numeric system of control can be built on standard machines or modular assemblies that can be produced to suit any application. The degree of complexity is regulated only by the imagination of the designer of the product/s and the number of modules he wishes to use to complete his desired quota.
All of the elements of component manipulation can be achieved by combining with multiple closed cups, pad cleaning, varying pad-stroke lengths, alternative pad shapes and a lot more. This type of system is often used where items must be printed in line with other assembly processes, or for complex multiple prints on different surfaces.
The flexibility of a Computer Numeric Controlled press comes close to producing the ideal machine for a particular application. Although a CNC press is substantially more expensive than that of a conventional pneumatic press. If the workload can justify the use of a CNC press for the increase in investment, then the CNC press is well worth considering.
Although it is wise to not be carried away by the current technology at hand, it still must be a capable printer.

My Bestfriend’s Name Is CNC: A Companys Perspective
CNC machine tools are praised all over the world because of three major factors: automation, accuracy and versatility. Human (operator) intervention is reduced to minimal levels because CNC machines can run on its own after it is programmed. Also, when the program is perfected, the CNC machine can run the instructions perfectly on its own.
Remember that any CNC machine can also be programmed to do special one-time tasks such as a dry-run, which will help the operator oversee what will happen when s/he leaves the CNC machine to do its tasks alone. Accuracy also goes hand in hand with repeatability. Again, once the program is perfected, the CNC machine can perform that task PERFECTLY even until 7 or 7000 times.
Lastly, versatility also works in the form of task memory that these CNC machines have. Once a program has been performed even for just one production run, it can be easily recollected the next time that the company needs the program. This saves time for setting up and loading of different programs.
The CNC sure simplifies the work of thousands of factories and machine shops worldwide. However, no matter how great CNC sounds like, it is something that doesnt fit in some industries. Like, perhaps, in the cosmetic industry, or in the show-business. Those examples are way too obvious. On the other hand, in these two major mechanical industries, CNC is almost synonymous to hero.
THE METAL INDUSTRY
Think of Metal. Metal. Perhaps the easiest metal that you can imagine is that ofa spoon. Now, imagine ANY spoon done with bare hands. After that, imagine a thousand spoons done with bare hands. Its so tedious you might even consider suicide if you are assigned to such a job.
The metal industry has been operating on CNC for ages. In fact, if you search CNC in the internet, you will instantly find metal companies topping the list. The major CNC centers that you will find in most metal machining processes are CNC turning centers, CNC machining centers, CNC grinding centers and CNC drill and tap centers.
Some of the CNC programs that are connected with the metal industry are milling, drilling, reaming, boring and tapping. Moreover, any metal that has any curved side have experienced some form of knurling, grooving, turning and/or threading.
Fabrication, in manufacturing, refers to processes that are executed on thin plates/sheets. These sheets are cut, punched, and bent to form their finishing shapes. CNC also stars in almost every aspect of metal fabrication.
THE WOODWORKING INDUSTRY
While the most beautiful wood-worked products are most likely hand-made, you cannot deny that a wide array of tools and furniture HAVE to be NOT hand-made to save time and for mass production levels. Theres just too much work and not to many hands. In light with this, CNC has worked wonders for this industry.
Important woodworking processes include cutting, framing, carving and engraving. The most useful woodworking CNC product is the CNC router table. It is capable of carving elaborate 2D and 3D designs. Moreover, it is also capable of material change while repeating the same design. Since contemporary furniture is often a splash of different materials (e.g. Wood, aluminum and/or plastic), any CNC router is capable of reproducing the same design EVEN in different kinds of materials by just altering the router bit.
Although many local, middle-sized enterprise owners are skeptical about using employing CNC in their manufacturing operations, there have been many success stories to sway them to using it anyway. In the Metal and Woodworking industries, CNC has proven itself time and again to be efficient.
It saves time and efforts in production and (more importantly) back-jobs. If youre venturing to one of these industries, remember that the word “labor” isnt something social anymore – its technological. And start calling CNC your best friend.

Motion Control – The Heart of CNC
What is Motion Control?
Motion control can be applied in many categories such as robotics, CNC operated machine tools and Kinematics, wherein motion control in kinematics are usually simpler. It can be mainly used nowadays with packaging, textile, assembly industries, printing, and semiconductor production. The hardware of a motion controlled machine usually consists of drive systems, motors, a computer, a PLC or Programmable Logic Controller to run the programs, and an amplifier.
The basic design of a motion control system would include a motion controller to produce a set of points including closing a position, a drive or amplifier to convert the control signal of the motion controller into a high power electrical current, an actuator, one or more feedback sensors, and mechanical components to convert the motion of the actuators to the desired motion.
CNC machines use programmable commands to make inputting motion to the machine easier rather than using cranks or other conventional machine tools. Almost all CNC machine tools can have programmable motion type (whether it would be rapid, linear or circular), the amount of motion, the feedback rate, and the axes to move.
Motion control is the simplest function of any Computer Numerical Control (CNC) machine. It is precise, consistent, and automatic system of control. CNC equipments need two or more modes of direction to which they are called axes. There are two common axis types and they are called linear and rotary. The linear axis type of motion control is driven along a straight path while the rotary axis type is driven along a circular path.
The operator of the motion controlled machine counting the number of revolutions made on the handwheel, added the generations of the dial would accomplish accurate positioning. The drive motor of the machine would be rotated to a resulting amount, which would then drive the ball screw, which would cause the linear motion of the axis. The feedback device at the end of the ball screw would confirm its revolutions.
The same linear motion can be found on a table vise. When you rotate the vise crank, it would also rotate a lead screw, which would then be able to drive the movable jaw in the table vise. In comparison to a motor controlled CNC machine, the linear axis in it is extremely precise compared to that of a table vise. This is because the number of revolutions of the axis drive motor in the CNC machine accurately controls the amount of linear motion along the axis.
A CNC command programmed and executed within a control of a machine would tell the drive motor of the machine as to how many number of precise times it would rotate. This in turn would rotate the ball screw then the ball screw would drive the linear axis. After the process has started, a feedback device located at the end of the ball screw would confirm the programmed number of rotations that the machine would run has taken in effect.
How would axis motion be controlled?
Utilizing a form of coordinate system would make axis controlling a whole lot simpler and more logical to the CNC control. Two coordinate systems that are being used in CNC machines that have been popular are rectangular and polar coordinate system, to which the more popular of the two is the rectangular coordinate system.
Graphing is a common application for the rectangular coordinate system and is needed to cause movement in a CNC machine.

Meet Your “Other” Employees: The Basic Parts of a CNC
Meet Your “Other” Employees: The Basic Parts of a CNC Machine
If you carve your name on a wood using a very sophisticated font, youre lucky if youll finish your first name in 24 hours perfectly. Years ago, wood crafting and metal crafting are very expensive massive- labor industries because every aspect of the manufacturing is done by hand. There was minimal machine intervention but the designs were still as intricate.
Today, with the help of technology, wood carving, metal molding, cutting and even finishing can be done simultaneously with minimal hands involved. In fact, a company is deemed unproductive if it mass produces products every day BY HAND.
CNC (Computer Numerical Control) machines are in demand in industries where hands are better off pushing buttons than doing actual labor. Businessmen are raving about this wonder-machine because it is accurate, speedy and flexible.
The CNC machine is actually a factory of its own. There are different parts that have specific functions. Lets get to know the factory workers.
THE VICE
The Vice is what holds the material which is to be cut or molded. It is important that the vice must be tight; so the material will be held securely. When the CNC machine starts to operate, the material will dash out of the vice if it is not secured. The vice usually works like a clamp that needs to hold the material not just securely but also in the right position.
THE GUARD
The Guardjust like any other guardworks like a protection to the person operating the CNC machine. Once the CNC starts working, scraps of the material can shoot off at high speed. This is very risky for the operator if a piece hits him/her. The guard completely covers all the hazardous sides of the CNC machine.
THE CHUCK
The chuck holds the cutting tool. Sophisticated designs require maximum chuck precision so the actual design can be realized.
THE MOTOR
The motor rotates the chuck at very high speed. It is hidden and protected inside the machine. You have to take care of this part very carefully. Nowadays, cooling and lubrication is automated in most CNC machines. Usually, if this part doesnt function well, it is the most difficult to treat. It is advised to have a CNC technician handy all the time.
THE LATHE BED
Like the sea bed, this is the sturdy base of the CNC machine. It is connected to the headstock and aids the carriage and tailstock to be parallel with the spindles axis. It is securely bolted so it remains unshaken by the vibration of the machine when it starts operating.
THE CUTTING TOOL/ CUTTER
This is the where the first-level shaping occurs. The cutter is usually made from high quality steel so as to cut the specific material fed to the CNC machine.
As a businessman, it is important that you get to know your employees, bond with them and earn their respect without scaring them. When you have CNC machines working for you, it is equally important that you understand them well. Do not be fooled by the CNC machine salesmen who court your interest because they are usually just after your purchase.
You have to master what comprises these machines, what makes them dysfunctional and most of all, what makes them stay in your company. Just dont start talking to them. That would be really, really, dysfunctional.

Industries That Constantly Define CNC Precision
Since the dawn of the CNC (Computer Numerical Control) machines introduction in the machining sector, they have been praised for being accurate, fast, consistent and flexible. Although CNC machines are not totally independent, a lot of major industries depend on these wonder machines. Common CNC-dependent industries include the metal industry and the woodworking industry. However, these industries, when small-time, can be operated by hands.
In this article, you will learn about the industries which are CNC dependent not because they have grown big in time but because they have to. It can be also that they are CNC dependent because their industries demand a low level of tolerance and a high level of sophistication. There are no small-time members of this industry. Lets start discussing.
THE AEROSPACE INDUSTRY
First off, this is already a very sophisticated industry. An engineering degree (solely) will not get you anywhere in the Aerospace industry. Not even within striking range. This industry demands so high from their members so machine shops that belong to this industry trust only the best of the best of CNC machining. In fact, sources say that the term Precision Machining has been coined from this industry.
In the materials they use, the aerospace industry already demands a lot. CNC machines which are used here are mostly capable of handling Inconel, Titanium, Magnesium, Stainless Steel and so much more. From parts of the landing gear, to shuttle seats, to housings, and even oxygen generation, CNC machines play a big part in their manufacturing.
Its not just that. Every CNC machine used in this industry also has to be approved AND RATED by the Federal Aviation Administration (FAA) to be safe and to be surely capable of Precision Machining. A NASA experience is highly praised too.
THE MEDICAL INDUSTRY
If the Aerospace Industry demanded precision above all, the Medical Industry demands sterility as much as precision. Thats something that you may have known since you got your first vaccine. Most CNC machines which work for this industry are multi-spindle and contain multi-turret lathes.
These special features allow the company to turn out components for hospital equipment, pulse meters, blood purification systems and mother medical devices. They are also useful in the mass production of disposable items and non-embeddable components.
High-torque milling and turning spindles are heavily demanded in this industry to enable users to process all substrates currently used in the medical device and orthopedic implant markets. Moreover, CNC machines recommended in the medical industry are those which can properly handle Titanium, Cobalt Chromium, Nitinol and others.
THE MILITARY INDUSTRY
This industrys main concern aside from precision is security. In fact, if you try to search online the CNC-manufactured materials or CNC machines used in this industry, no matter how famous their reputation is, the manufacturer cannot display (pictures of) the materials that they have produced for their clients. They can only display products which they are used in.
This industry deals heavily with Inconel, Titanium, Kevlar, Monel and Hastealloy; so most CNC machines recommended in the Military industry must be able to handle those.
Famous CNC standards evaluators in this industry include the Department of Defense (DOD), the Mil Spec (Military Specifications) and other selected military sectors.
The top managers of these industries also demand their CNC machines to be purchased from CNC machine suppliers which adhere to the International Standards Organization (ISO). And because these industries are CNC-dependent, their shops can occupy a vast amount of space. Basically, that makes no room for old school methods and errors.

In Depth Discussion In Planning CNC Programs
Understanding the Computer Numerical Control Machine as well as learning the method of programming these machines is not enough to maximize the capability of these devices. Even if you are proficient on those two stated above, proper understanding of the step by step procedures is still important.
In this article we would talk about the step by step procedures of programming Computer Numerical Control Machines which is recommended by the most experienced CNC Machine Operators and progammers.
Step by Step procedures in planning of a CNC program
Whenever we try to program a Computer Numerical Control Machine the first thing that the Machine operator should consider is the blueprint of the part we are trying to manufacture. Proper understanding and reading of a blueprint is a basic and the most important skill in the manufacturing Industry that engineers, managers, CNC machine operators as well as CNC programmers should know about.
Proper understanding of these blueprints should help the CNC machine operator as well as the programmer to use the appropriate CNC machine to be used.
The second step on the proper programming of a Computer Numerical Control Machine is by selecting the appropriate type of Machine that will be used. This is where the proper understanding of each machine type comes into play. Knowing the type of design, specifications as well as features of a machine will help you on choosing the appropriate one.
The third step would be the analysis of the operations or the setup sheet. The setup sheet is used to describe the necessary processes needed to create the parts on a CNC machine. The setup sheet includes the proper machine sequence and also the tools and cutting data to be used. Specifications written on the setup sheet aids the programmer on the proper algorithm needed by the Computer Numerical Control Machine.
The fourth step on the step by step requirements would be the proper selection of the tools required to create the parts. This step is important on the industry manufacturing practices, basically the tools to be chosen is based on the common sense and Good CNC operators and programmers should be aware of them. Usually there is a certain checklist on this step, the most important point of this checklist would be knowing the material to be machined as well as its characteristics.
Fifth step would be the calculation of the cutting data. Proper calculation is one of the important steps in the planning process. This is where the spindle speed, federate value, cutting speed and the depth of cut is calculated to fit to the specifications in the blueprint.
Sixth step would be the actual programming process, this is also the step where the proper Units are inserted into the programming algorithm of the Computer Numerical Control Machine. This is where we incorporate all the codes that are needed to run the whole CNC machines in the CAD software.
Programming Considerations
In order for other programmers to analyze and append your algorithm, it is important to have certain programming considerations. These program considerations were suggested by experienced Computer Numerical Control Machine Programmers and Operators.
First it is important that you develop a programming technique that will be readily understood by other developers, with a good programming technique programs could easily be appended if there are any errors.
Second, it is also important to proofread all programs for typographical errors before being executed in the CAM software, this is to ensure that the CNC machine would operate its desired operation. And most important of all is to keep your programs as simple as possible in order for the machine to process the instructions faster.

How To Effectively Consider CNC
In the employment world, the phrase manual labor is often associated with jobs which are dirty, psychologically sickening, or worse, both. Small to medium-size manufacturing enterprises are moving towards using the CNC(Computer Numerical Control) in their major manufacturing processes because of its fame in accuracy, flexibility and automation. If youre one of these entrepreneurs, dont jump in the bandwagon just yet.
Acquiring a CNC machine is more than just buying additional equipment; it also has a social aspect in it. Here is the low down:
PEOPLE-WISE
First, you have to consider the people who are working in your shop. How many people will be displaced if you buy a CNC machine? Keep in mind that a CNC machine is multi-operational; so its possible that a couple of laborers will be erased from the production team. Experts say that the healthy ratio is at least one-sixth (1/6) of your whole labor force.
You will be saving time and effort, yes, and that is the best thing about having a CNC machine. However, you might be worrying about actually terminating people because, to put it bluntly, you wont need them anymore. A CNC machine, just like any machine, will need an operator. Instructions used by a CNC machine for operational execution are composed of CNC words/codes and is in the form of a sentence.
Does one of your people ever have experience with a CNC machine before? Can s/he formulate CNC instructions? If the answer to both questions are yes, then thats absolutely good news. However, if you answered no to at least one of the questions, then there are more things to evaluate.
Are your people capable of fast-learning? If it pains you to terminate them because they have been good employees in the past, train them on how to use the CNC machine and how to compose instructions for it. There are plenty of free training kits online.
COMPANY-WISE
Theres a corporate adage that goes: Innovate or die. Theres a lot of truth in that. A purchase of any CNC machine symbolizes a companys decision to innovate to increase productivity. However, there are a few things that you need to note.
Review your companys history. How long should you innovate drastically in terms of production? CNC equipment is expensive. It is an investment. In the long run, you may be forced to buy new equipment more often. Consider CNC heavily if you feel that your company innovates faster than other companies in terms of the industry that you belong to. After all, you can easily alter designs and material when you have CNC powered operations.
In most companies, Innovation is another word for saving. It means saving time, effort and space. In using CNC machines, the first two factors are sure savings while the third is not. People doing the labor and CNC machines often occupy the same amount of space. Do not romanticize a clearing of clutter effect when you buy a CNC machine. You will keep up, in terms of production; but CNC equipment also occupies a lot of space. So in that aspect, its pretty much the same thing.
Another thing that you have to be reminded of is the level of accuracy that your company needs to produce. Intricate patterns on metal/wood will DEMAND CNC accuracy. So any time that you feel your company is ready for such innovation and accuracy, consider employing CNC in your manufacturing.
At the end of the day, the last aspect that you need to evaluate is you, yourself. As the owner/head manager, you have to KNOW AND UNDERSTAND the CNC machine and the software well. This is the biggest battle that you have to face.
The equation to improvement is simple a really good machine plus a really good operator (you). Do not easily be blinded by the salesmens poetry.

How CNC Helps Companies
The advent of Computers lessened the need for human intervention in almost all aspects of our daily lives. This is especially true in the industrial sector now that production is virtually automated.
Precision and accuracy
Computer numerical control has been able to help companies in terms of precision. With the need for more complex designs and more complex operations, human workers could not cope with the required precision that comes with advancement. CNC machines were able to alter that idea by allowing increased precision and lesser error ratios with regards to production.
Another important improvement that CNC has brought with it is the increased accuracy. The dimensions of components have to be very accurate. And since an increase in production speed also increases the error ratio, CNC has helped lower that ratio by the increased level of automation and the error detection capabilities that computers have.
Speed
In the industrial sector, speed is of the essence. With CNC technology, the normal production capacity has been increased exponentially. This means that effective and accurate production methods have been developed. Mass production requires more scrutiny for errors and mistakes. However, anomalies can also be corrected. The programming structures of CNC machines can be altered in a fast way. This means that mistakes do not have as serious an impact as they had before CNC was improved to this level.
Machine versatility
CNC machines have become very versatile with regards to the tools that they use. They can easily be assigned to different tasks and thus can be very productive. Tools and networks can be switched without compromising the speed of the production. Aside from this, one machine can do more than one task at a time. This exceeds the normal human capacities as it allows more tasks to be accomplished at a faster rate than before.
Furthermore, when one machine tool breaks down, it can easily be pulled off the grid to prevent it from affecting the whole production cycle. It can then be replaced or repaired on the spot.
Lesser human intervention
Since component production is a very tedious and repetitive operation, human error skyrockets as time passes. This is due to fatigue and other factors. Furthermore, the ability of a person degrades due to psychological and emotional factors. This means that if a person works on the same job for a certain amount of time, the person may eventually get bored or tired or both. This increases the possibility for the human to commit an error and thus causes a drop in the efficiency rating of that person. A machine, however, does not get tired or bored. A machine does not have any concern at all.
Therefore, a machine increases efficiency ratings by speeding up production and eliminating or reducing factors that threaten efficiency. In this case, one must simply program the machine to start a cycle. Furthermore, humans have to be fed, paid, and rested. Machines only have to be rested when failures occur to often and they do not need to be paid or fed.
This brings us to the conclusion that companies will be able to save a lot in the long run. While investing in CNC machines is not cheap, maintenance will only cost a fraction of what will be paid to manual laborers.

Data Transfer Methods of CNC
A CNC machine cannot function without a program. And a program cannot make its way to the machine without an effective data transfer system. So, what are the methods of data transfer and how effective are they in conveying data from one point to the next?
Punched tape
The first data transfer method is the punched tape. It consists of a long strip of paper with holes punched in it to store data. The holes represent a set of data that tells the machine how to move and what to do.
This method has proven to be very versatile and very useful. It has proven to withstand the test of time as numerous magnetic storage devices have deteriorated over time even to the extent of being unreadable while punched tape has been shown to be fine decades and perhaps even centuries later. Repair is also not a problem as specially designed splices can put two end together virtually unchanged. Furthermore, punched tape can be visually decoded should the need arise. This means that human accessibility is also not a problem.
Floppy Disk
While punched tape is quite a long roll of paper, a floppy disk is a small magnetic storage device that is more space efficient than punched tape. It can also be used to store simple programs.
Floppy disks virtually revolutionized the way data could be stored and transferred from one point to another. It allowed users to store and transfer data faster than punched tape allowed. Furthermore, the data within a floppy could be easily edited at any point as long as you have the proper program to read it. However, this method has proven to be quite problematic in the long run as floppies have a tendency to degrade alarmingly fast. A floppy could be unreadable after only 3 years.
RS232
This method is actually a set of standards for serial binary signals that connects between computers, terminals, and modems. This is a fast and efficient way to transfer data.
This cable connects a CNC machine to a computer that has floppy disk support thus eliminating the need for punched tape. This allows the operator to input data remotely and even while accomplishing other tasks. However, it need to be used in conjunction with an effective data storage device so as to have backups in case of emergencies.
Networks
Networks are a set of computers that are linked together to make data sharing easier. In an industrial scenario, networks allow a number of different users to individually create a program for the machine to run on.
This method allows multiple users to access and transfer data remotely. This allows for a faster and more efficient check-and-balance system for the programmer and the data verifier. Furthermore, different parts of the program can be completed by different programmers and then compiled by one user. This makes program creation a fast and easy process.
Manual Data Input (MDI)
MDI allows users to input commands directly into the CNC machines memory. This may seem to be an effective way of telling the machine what to do but it actually has a lot of drawbacks to it.
Despite it being the fastest way of telling the machine what to do, it is also a very risky and tedious operation as it requires the use of the machines terminal. Furthermore, the construction of a program is not as fast as opposed to the network method. It only allows one user to access the machine thus making it a long and drawn-out process.
Another disadvantage that comes with MDI is that it limits the operator to only one task at a time. However, MDI allows the most control over the machine compared to other methods.
