Title:
GRINDING PROCESSING METHOD AND NUMERICAL CONTROL GRINDING MACHINE
Document Type and Number:
Japanese Patent JP3850224
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a grinding processing method and a numerical control grinding machine for executing the grinding processing method in which a recessed part is not generated on a contact surface of a work at the time of completion of the grinding processing with a grinding wheel and a processing time is shortened in the grinding processing method of a non-circular or circular work.
SOLUTION: The grinding wheel carries out a profile-forming motion with a rotation of the non-circular or circular work by a finishing shape profile data of the work and is cut-in at a predetermined cut-in angle of the work corresponding to a grinding processing step to carry out a grinding processing. After a finishing grinding is completed, the grinding processing is carried out by relieving the grinding wheel over a predetermined relief angle based on a synthesis data obtained by synthesizing the finishing shape profile data and the grinding wheel relief data. The cut-in angle at the final finishing grinding is made smaller than the grinding wheel relief angle.
