CONTOURING GRINDING METHOD, AND METHOD AND DEVICE FOR SETTING FEED SPEED IN GRINDING

摘要

PROBLEM TO BE SOLVED: To perform the grinding at the optimum feed speed while maintaining the requested grinding accuracy by controlling the feed speed of a grinding wheel to perform the contouring grinding so that the operated grinding error is equal to or less than the requested grinding accuracy. ;SOLUTION: The sectional area of the grinding margin to be removed is operated for each pitch of a grinding wheel 11, and the grinding reaction is operated based on the sectional area of the grinding margin. The displacement of a tip part of the grinding wheel 11 is operated based on the grinding reaction to obtain the grinding error, the relative feed speed of the grinding wheel 11 relative to a work W is operated by a control device 21 to perform the grinding. The grinding can be performed at the optimum feed speed while maintaining the requested grinding accuracy, and the whole grinding time can be reduced.;COPYRIGHT: (C)1998,JPO
