Abstract
This study is to investigate a methodology of automatic finish grinding of a curved surface generated in the previous process and to develop the prototype machine. The principle of this method is to control the feed motions of the grinding tool based on a definite relation between stock removal rate and torque actuated on the grinding tool. The machine consists of torque detector, analogue calculator to determine the horizontal and vertical feed rate components referring to the torque sensed, and servo mechanism. The drawback of this method that is the stock removal rate differs a little between positive and negative slopes of surface profile. The error can be tolerably reduced for practical application by refining the detecting system and by introducing an elastic finishing tool.
