CNC is the short form for Computer Numerical Control. The CNC machine comprises of the mini computer or the microcomputer that acts as the controller unit of the machine. In CNC machines the program of instructions is fed directly into the computer via a small board A . In CNC machine the program is stored B .The programmer can easily write the codes, and edit the programs as per the requirements. New systems can be incorporated into the CNC controller C . Some of the common machine tools that can run on the CNC are: D . The main purpose of these machines is to remove some of the metal so as to give it proper shape such as round, rectangular, etc. In the CNC machines the role of the operators is minimized. The operator has to merely feed the program of instructions in the computer, load the required tools in the machine, and E automatically. You don’t have to worry about the accuracy of the job; all the CNC machines are designed to meet very close accuracies. In fact, these days for most of the precision jobs CNC machine is compulsory. When your job is finished, you don’t even have to remove it, the machine does that for you and it picks up the next job on its own. This way your machine can keep on doing the fabrication works F___, of course you will have to feed it with the program initially and supply the required G. Most of the manufacturing companies are now equipped with the CNC machines as the markets have got very competitive; however, getting the expert labors for operating these machines is becoming quite difficult. Even the machine operators of these days prefer to operate the machine by programming H___. In most of the machine tools training institutes I CNC machining andprogramming.
1. the rest of the work is done by the computer
2. in the memory of the computer.
3. the new operators are taught manual machining as well as
4. Lathe, Milling machines, Drilling Machine etc.
5. instead of operating it manually
6. raw material
7. similar to the traditional keyboard.
8. all the 24 hours of the day without the need of muchmonitoring
9. simply by reprogramming the unit.
