<P>PROBLEM TO BE SOLVED: To properly edge a shaving cutter even if the outer diameter and the tooth thickness of the shaving cutter are reduced by edging of the shaving cutter. <P>SOLUTION: In a personal computer 10, a correction coefficient α for correcting a tooth profile error and a correction coefficient β for correcting an engagement position are set for each quantity of edgings and for each cutter specification of the shaving cutter. Target tooth profile data Do, tooth profile error data ΔD which is the deviation between the target tooth profile data Do and the tooth profile error data ΔD, and a correction coefficient α and a correction coefficient β taken in according to the quantity of edgings and the cutter specification are applied to the expression Dcc=Do+α*ΔD+β to obtain target tooth profile data Dcc. Shaving cutter tooth profile data ds is obtained from the target tooth profile data Dcc. <P>COPYRIGHT: (C)2011,JPO&INPIT |
