PCT No. PCT/JP82/00197 Sec. 371 Date Jan. 27, 1983 Sec. 102(e) Date Jan. 27, 1983 PCT Filed May 26, 1982 PCT Pub. No. WO82/04210 PCT Pub. Date Dec. 9, 1982.The present invention has for its object to make it possible to stop the relative movement of a cutter and a gear blank or change its speed during cutting in a numerical-controlled machine tool for cutting a gear, such as a gear hobbing machine, a gear grinding machine or the like. To perform this, two kinds of pulse distributors, i.e. a synchronization control pulse distributor (152) and a tooth profile forming pulse distributor (153) are provided; the synchronization between the rotation of a cutter (110) and the rotation of a gear blank is provided by the synchronization control pulse distributor (152); and an additional rotation of the rotary shaft of the gear blank necessary for forming the tooth profile of a gear is effected by the tooth profile forming pulse distributor (153). |
