1Introduction

Cutter Radius Compensation Machining a workpiece has to be done with tools of different radii. Radius compensation has to be introduced in order to write the actual contour data of the part in the program, instead of the path covered by the tool center (taking into consideration the tool radii). The values of radius compensations have to be set in control system. Hereinafter reference can be made to cutter compensations at address D in the program.

Wear Compensation

The tools are exposed to wear in the course of machining. Allowance can be made for such dimensional changes (in length and radius as well) with wear compensations. The tool wear can be set in the control system. A geometry value, i.e., the initial length and radius of the tool, and a wear one belong to each compensation group (referred to at address H or D). When the compensation is set, the control will compensate the movement with the sum of the two values.
