The term interpolation refers to an operation in which the tool moves
along a straight line or arc in the way described above.
Symbols of the programmed commands G01, G02, ... are called the
preparatory function and specify the type of interpolation conducted in
the control unit.

Some machines move tables instead of tools but this
manual assumes that tools are moved against workpieces.
Threads can be cut by moving the tool in synchronization with spindle
rotation. In a program, specify the thread cutting function by G32.
