Title:
METHOD FOR CALCULATING PHASE AND GRINDING PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2020023034
Kind Code:
A
Abstract:
To provide a method for calculating a phase which can calculate a phase of a work-piece with high precision in a short time without using phase references of a pin, a key and the like and a touch sensor and the like for determining a phase in a grinding machine, and a grinding processing method.SOLUTION: A grinding machine 1 causes a grinding wheel 17 to contact with an eccentric portion Wa, a portion to be processed of a work-piece W stopped at an arbitrary rotation position by relatively moving a grinding wheel head 16 in an approaching direction and acquires a rotation phase of a main spindle 1a and a feeding position for the grinding wheel head 16 at the time when the contact is detected, so that the machine can calculate a processing reference phase of the work-piece W.SELECTED DRAWING: Figure 6
