Abstract: Both the rough rolling and finish rolling rack type tools were prepared for two step works. And the production for a lathed blank was tried to make a more precice involute gear of stub tooth. An accuracy of tooth face of rolled piece was graeatly influenced by a shape at the top flank of rough rolling tool and its setting position against the gear blank. Then, those conditions in the two step gear rollings were experimentally investigated to improve the accuracy of the rolled profiles. In consideration of the 1st report, the pair tools of a new round-flat type were designed and examined by rolling the workpiece (module 1.5,pressure angle 24.5°, number of teeth 28 and whole depth 2.7mm). And the accuracy of the rolled involute profiles were compared and investigated. As the results, the accuracy of the rolled pieces were improved. That is, it was revealed that the combinative system with the new designed rough rolling tool and the finish rolling tool was useful for the two step rollings.
