CNC - STAGES IN CNC WORK

HOW TO USE A TYPICAL CNC MACHINE
   

1. The design is loaded into the computer which is attached to the CNC machine. The computer changes the design into a special code (numerical) that controls the way the CNC cuts and shapes the material.

   

2. The material to be shaped is taped on to a block with double sided tape. This must be done carefully so that it does not come off the block during machining.

   
 
   

3. The block is then placed in the vice, inside the CNC. It must be tightened up carefully. If it is not secure when the machine starts to cut the material it can come away from the vice. When the machine starts working, the vice moves up, down, right and left according to the design.

   

4. The guard is placed in position. It protects the machine operator in case the material is pulled out of the vice by the power of the cutter. For safety reasons, if the guard is not in position the motor will not start.

   

5. The CNC is turned on and the shape is cut from the material. When the cutter has stopped the shaped material can be removed from the vice. Total time - for simple designs - 15 minutes.

   
 
   

In your own words and with the help of diagrams, explained the stages involved in the use of a CNC machine such as the one shown above.
