An Integrated Sensor System for Size and Roundness Control in Plunge Grinding

An integrated sensor system is proposed for size and roundness control in plunge grinding. The sensor system measures the size and roundness of cylindrical workpieces and also the wheel power during grinding. A fast in-process size evaluation method used by the system is discussed and experiments for assessing the accuracy of the system are presented together with analysis of the results. The effects of grinding conditions such as friction, long time contact and system drift upon performance are assessed and suggestions are made for obtaining a high performance from the sensor system. © 1992
