MACHINING METHOD OF WORK PIECE, GEAR PRODUCING MACHINE, COMPUTER SYSTEM, AND DRIVING POWER TRANSMITTING APPARATUS BY OBLIQUE GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To realize specific correction in a work piece surface as directed crowning without deviation in configuration.SOLUTION: By changing the position of a dresser relatively to a tool during dressing according to a rotation angle of the tool or according to the position in a width direction of the tool, the specific correction is carried out on a surface shape of the tool. Specific correction is carried out in the surface shape of the tool which has at least a topical constant value in a first direction of a tool in a generated pattern and being represented by a function Fin a second direction of a tool extending vertical relatively to the first direction. Due to correction of the tool by the oblique generation method, corresponding correction is carried out on a surface of a work piece. The specific correction on the surface of the work piece is directed crowning having no deviation in configuration.SELECTED DRAWING: Figure 8
