Interpolation refers to an operation in which the machine tool moves along the workpiece
parts. There are five methods of interpolation: linear, circular, helical, parabolic, and cubic.
Most CNC machine can provide linear interpolation and circular interpolation. The other
three methods of interpolation (helical, parabolic, and cubic interpolation) are usually used
to manufacture the complex shapes, such as aerospace parts. In this manual, linear and
circular interpolation are introduced.
