GRINDING ATTACHMENT FOR FORMING CONTOUR RAKE SURFACE HAVING VARIABLE AXIAL RAKE ANGLE AND METHOD FOR FORMING CONTOUR RAKE SURFACE HAVING VARIABLE AXIAL RAKE ANGLE

摘要

PROBLEM TO BE SOLVED: To provide a grinding attachment capable of manufacturing an improved milling cutter tool.;SOLUTION: A control device 39 has (a) a front tip space module 41 for guiding a grinding tool 37 for processing a preset front tip space, (b) an outer peripheral tip space module 43 for guiding the grinding tool 37 for processing a preset outer peripheral tip space, and (c) a square tip space module 47 for regulating a square rake surface 23 on the basis of a preset front cutting edge 8 and a preset outer peripheral cutting edge 16. The control device correspondingly controls a positioning device 38 for forming the square rake surface 23 by the grinding tool 37.;COPYRIGHT: (C)2005,JPO&NCIPI
