NC Part Programming

A part program consists of series of coded instructions that direct a CNC controller to cut the part along with the desired profile or locations. Part programming starts with a process planning that includes all of the information a CNC operator requirements for producing workpiece. Based on the size of organization, process plan is simulated by a process planner or an NC programmer.

The main tasks involved in part programming are:

• Tool selection and tooling sheets preparation
• Process planning
• Work holder selection and layout sheet preparation
• Liaison to designers and NC operators
• Part program preparation
• Machine selection
