What Is a CNC Machine and How Is It Built?

What Is a CNC Machine and How Is It Built?

A CNC system consists of three fundamental elements:

  1. Part program
  2. CNC control unit
  3. Machine mechanics and cutting or drilling tools, such as drill bits, milling cutters and saw blades

Part Program: The part program is the sequence of instructions that the machine mechanisms and axes must follow. Each command defines a position in the Cartesian coordinate system or specifies motor travel, speed, the tool to be used and the required machining operation.
