Easy
The function of interpolator in a CNC machine controller is to
- Acontrol spindle speed
- coordinate feed rates of axes
- Ccontrol tool rapid approach speed
- Dperform Miscellaneous (M) functions (tool change, coolant control etc.)
Explanation
The interpolator computes and coordinates the feed rates of the individual machine axes so their combined motion traces the commanded tool path (straight line, arc, or contour) accurately.
