The IGNOU has a CNC part in machining programming. The Machining involves an important aspect of relative movement between cutting tool and workpiece.

In machine tools this is accomplished by either moving the tool with respect to workpiece or vice versa. In order to define relative motion of two objects, reference directions are required to be defined.

A program defining motion of tool / workpiece in this coordinate system is known as a part program.

Lathe and Milling machines are taken for case study but other machine tools like CNC grinding, CNC Hobbing, CNC filament winding machine, etc. can also be dealt with in the same manner.
