Title:
METHOD FOR DETECTING GRINDING END POINT FOR CYLINDRICAL WORKPIECE AND DEVICE THEREOF
Document Type and Number:
Japanese Patent JP2002028859
Kind Code:
A
Abstract:

To provide a method for detecting a non-contact type grinding end point for a cylindrical workpiece.

The method for detecting the grinding end point for the cylindrical workpiece w when an outer periphery of the workpiece w is ground by a rotating grinding wheel 3, while rotating the cylindrical workpiece w, and the workpiece w has a desired dimension ground by r in the radial direction of the workpiece w is characterized by applying laser beam when starting the grinding of the workpiece on front and rear slide tables, measuring a distance Li from a laser displacement sensor 6 to the outer periphery of the workpiece in grinding w by using the laser displacement sensor 6 provided at a position in a direction perpendicular to an axial center of the workpiece w and determining grinding end of the cylindrical workpiece w when a displacement width (Δ=L0-Li) of a distance L0 up to the outer periphery of the workpiece w when starting the grinding and the distance Li during grinding becomes r.
