ABSTRACT:
An angled cam bar is slidable across a pair of base-carried supports so that the cam bar attitude varies in its travel, and a pivot point on the cam bar thereby traces out a locus of curvature, while a dressing stylus depending from the pivot point likewise traces out the locus of curvature on a grinding wheel. The supports are biased to a first position so as to generate a first portion of the locus of curvature, and means as provided to move one of the supports at one end of the first locus portion so as to generate a second portion of the locus of curvature as the bar continues traversal.
