Abstract

In the cam-controlled "sizematic" type grinding method and apparatus therefor, a novel "in process" "gagematic" type measuring means has been introduced so as to maintain the strong points of the former and develop a new grinding method and apparatus capable of securing high precision and fine surface finish of workpieces at the same time. For attaining the above purpose (a) a novel process of comparing the timing of signals of reaching the target final dimension and lapsing of the minimum required "spark-out" grind time and (b) a compensation process for wear of the dresser point are introduced.
