ABSTRACT:
Method and apparatus for stock dividing gear-shaped workpieces mounted on the work spindle of a gear-finishing tool. A work spindle encoder provides instantaneous angular position information when the surface of leading and trailing flanks of the workpiece teeth are sensed by a probe. This instantaneous position information is used to generate two sets of measured error values which relate, respectively, to the leading and trailing flanks and which are indicative of the differences between the sensed surrfaces and the desired surfaces of a correctly-sized gear. These sets of error values are analyzed using fourier transform techniques to generate (a) a first harmonic for each set and (b) a set of modified error values for each leading and trailing flank corresponding to each respective first harmonic. The largest and smallest modified error values of each set are used to simulate the opposite sides of the largest and smallest "effective" (as different from "actual") tooth spaces of the unfinished workpiece, and these effective spacings are compared to the desired correctly-sized tooth space of a finished gear to generate a correction value for adjusting the angular position of the workpiece relative to the finishing tool prior to initiation of the finishing process. In the preferred embodiment, a non-contact probe is used for sensing the flanks of the workpiece so that the entire stock division procedure takes only a relatively few seconds.
