Abstract

PURPOSE:To easily perform gear cutting of a rack even with a shaft angle except 90 deg. in a shaping machine performing gear cutting of the rack, by providing a mechanism gradually adjusting a moving amount in both end parts as compared with a moving amount of the axially central position of the machined rack. CONSTITUTION:A machined rack 2 is fixed onto a table 11 to set a slope for a saddle 25 of a table mount 15 to a desired angle, and then a cutter 1 is driven in rotary reciprocating motion by a motor 3, simultaneously a feed screw shaft 14 is rotated through a worm 12a to linearly move the table 11 to the direction of an arrow head D. Further a generating ratio converting cam 22 is rotated by rotary motion of a center shaft 13, and a cam follower 23 is moved to the direction of the arrow head D by a lift amount of the cam 22, then the screw shaft 14 is linearly moved to the same direction. In this way, the table 11 is linearly moved by a correction moving amount of increasing or decreasing the moving amount from the cam 22 for the moving amount from rotation of the worm 12a, and the rack with a shaft angle except 90 deg. can be easily performed gear cutting.
