Part program

The part program is a sequence of instructions, which describe the work, which has to be done on a part, in the form required by a computer under the control of computer numerical control (CNC) software. It is the task of preparing a program sheet from a drawing sheet. All data is fed into the CNC system using a standardized format. Programming is where all the machining data are compiled and where the data are translated into a language which can be understood by the control system of the machine tool.

The machining data is as follows :

  1. Machining sequence classification of process, tool start up point, cutting depth, tool path, etc.
  2. Cutting conditions, spindle speed, feed rate, coolant, etc.
  3. Selection of cutting tools.
