Quizplus · Accepted Answer

The clearance plane is the standard practice for establishing a safety zone above the workpiece or workholding device in CNC mill programming. This is done to ensure that the cutting tool does not accidentally come into contact with any fixtures or clamps holding the workpiece, which could damage the tool or cause injury to the operator. A change plane refers to a designated height where the cutting tool should be changed or rotated. Cutter offset is a setting used to adjust the position of the cutting tool relative to the workpiece, and dwell refers to a programmed pause in the cutting operation.
