ABSTRACT:
When machining cams with the same profile data, finished shape errors tend to increase as the diameter of a grinding wheel decreases. In order to keep the finished shape errors within a tolerance, the profile data used for machining must be renewed with new profile data corresponding to the present diameter of the grinding wheel. In the disclosed numerically controlled cam grinding machine, optimum wheel diameters, at which new profile data must be calculated, are decided automatically. The numerical controller calculates the marginal diameters which require renewal of profile data based upon the machining tolerance when a new grinding wheel is attached to the wheel head. After that, the numerical controller calculates new profile data from the marginal wheel diameter and lift data, when the present wheel diameter reaches into one of the marginal wheel diameters. The old profile data is renewed with the newly calculated profile data corresponding to the marginal wheel diameter.
