The geometric accuracy of gears obtained by injection molding before and after finishing by shaving process has been compared. Significant assumptions in the application of this method to the finishing of polymer gears are presented. There is a clear influence of the applied technology on the dimensional stability improvement of the tested gears rim made of composite PA66 matrix containing 35 wt % glass fibers. The tested gears made of the composite materials used in some drive systems can successfully replace this type of machine elements made of metals.
