Abstract
A grinding wheel with a working surface having a complex profile is subjected to a path-controlled dressing operation by an apparatus which moves in the direction of the Z-axis of the machine while the grinding wheel moves in the direction of the X-axis. When necessary in view of configuration of the momentarily dressed portion of the working surface, the grinding wheel is turned about the B-axis of the machine, and such axis is remote from the point of contact between the dressing tool and the working surface and is normal to the Z- and X-axes. The controls of the grinding machine cause the dressing tool and the grinding wheel to perform additional movements in the direction of the Z- and X-axes so as to compensate for those deviations from the preselected movement which are due to turning of the grinding wheel about the B-axis.
