Post-process sizing control device for grinding machine

摘要

A post-process sizing control device is provided with origin compensation means for controlling a size measuring device to measure (18) an actual size of a workpiece portion and for compensating the origin of a wheel head (19) by a position compensation amount which corresponds to a difference between the actual size and a theoretical size derived from calculation and size measuring interval setting means for setting the number of workpieces which should be ground during the next size measuring interval which begins after the preceding origin compensation operation and ends with the next origin compensation operation. The size measuring interval setting means sets the number of workpieces which should be ground during the next size measuring interval, based on an average position compensation amount derived by dividing a position compensation amount for the last workpiece ground during the present size measuring interval by the number of workpieces ground during the present size measuring interval.
