摘要： PURPOSE:To make uniform the quantity of grinding with a grindstone, by altering the revolution speed of the surface of a cam as a function of the rotation angle of the cam. CONSTITUTION:A cam shaft 12 fitted with cams 14 at axial intervals is supported on a cam profile grinder 10 including a headstock and a tailstock. The profile of the cam 14 is shown in the drawing. While the bottom B of the cam 14 which is defined by a radius of R is in contact with a grindstone 16, the cam shaft 12 is rotated at a constant speed of VB so that the quantity of grinding of the cam with the grindstone is made uniform. The flat portions F1, F2 and protruded portion N of the cam 14 are ground at speeds of VF and VN, respectively. These revolution speeds, the feed of the grindstone 16 and the swing of the headstock and the tailstock are determined according to a predetermined program so that the quantity of grinding is made uniform.
