Abstract

A method for controlling a machining process of a workpiece includes a step of measuring amounts of machining of the workpiece by a plurality of sensors located at different positions on the workpiece, the sensors providing detection signals which represent the respective measured amounts, a step of removing the detection signal when the detection signal has an abnormal value which is extremely different in comparison with values of the other detection signals by using a smoothing method, and a step of controlling the machining of the workpiece depending upon the remaining detection signals from the sensors.
