Abstract
A doubly dished or double-cone grinding wheel or a pair of singly dished or single-cone grinding wheels are reciprocated in strokes along the tooth flanks or a helically toothed gear wheel to grind the gear. The stroke motion is controlled in dependence of measured values of the generating motion and of the momentary position of the grinding wheel or wheel pair upon the tooth flank being ground. For this purpose, a grinding reference polygon determining the grinding stroke limits is constructed from the gearing specifications or data. An effective grinding point of the grinding wheel or wheel pair is then determined at short time intervals from measurements of the momentary generating and stroke position of the machine. The spacing of this effective grinding point from the subsequent grinding stroke limit in the grinding stroke direction is determined. Finally, the grinding stroke motion is controlled in its path and speed such that it reverses at each grinding stroke limit defined by the grinding reference polygon.
