ABSTRACT:
A grinding method for grinding non-circular workpiece such as a cam. The grinding wheel is moved according to the profile data defining profile generating movement of grinding wheel and cut-in feed data defining cut-in feed movement of the grinding wheel. In a part of each revolution of the workpiece, where the acceleration of the profile generating movement become zero or a negative value, the profile generating movement according to the profile data and the cut-in feed movement according to the cut-in feed data are executed simultaneously. Then, in the remainder of each revolution, the profile generating movement is executed without cut-in feed. The above-mentioned process is repeated alternately until the total amount of cut-in feed reaches a predetermined value.
