Abstract

A process is applied for grinding cams of a camshaft (12) by means of a numerically controlled camshaft grinding machine (10). The camshaft (12) is arranged in a workpiece mounting (11) rotatably at preset angular velocity (.omega.) in predetermined angle steps about its longitudinal axis. A grinding wheel slide (17) with a grinding wheel (18) is infeedable in an axis (20) vertical to the longitudinal axis in preset steps. A grinding wheel (18) is selected as to its condition for machining as a function of the geometry, the material and the required surface condition of the camshaft (12) and cams (30), and the infeed of the grinding wheel (18) is set. In order to achieve a minimum grinding time while taking into account various process-related restrictions, a maximum possible infeed for a minimum grinding time is determined using the maximum relative metal removal rate and the preset cam geometry, and--if necessary taking into account restrictions with regard to the chip cavity repletion conditions and the grain load--the maximum infeed for grinding the camshaft (12) is set (FIG. 1).
