Abstract

The invention provides a method for trimming a resin base circle arc diamond grinding wheel by adopting a rotary green silicon carbide grinding bar, and belongs to the technical field of machining of the resin base circle arc grinding wheel. The method aims to solve the problems that the installation position deviation, in the vertical direction, of the grinding wheel in a grinding process affects the shape accuracy of a machined workpiece, and machining accuracy is low. The method comprises the steps that firstly, the green silicon carbide grinding bar is arranged on a vacuum chuck of a workpiece main shaft of a three-linear-axis linkage machine tool, and the grinding wheel is arranged at the lower end of a grinding main shaft of the three-linear-axis linkage machine tool; then, a trimming path of the grinding wheel is planned, and the grinding wheel starts to be trimmed; every time the next adjacent interpolation period T starts, the radius R of the current green silicon carbide grinding bar is collected, the trimming path is corrected, and the grinding wheel continues to be trimmed by adopting the corrected trimming path until trimming is completed. The method is used for trimming the resin base circle arc diamond grinding wheel.

Description

technical field [0001] The invention relates to a method for dressing a resin-based arc-shaped diamond grinding wheel by using a rotating green silicon carbide grinding rod, and belongs to the processing technical field of the resin-based arc-shaped grinding wheel. Background technique [0002] In recent years, spherical, aspherical and free-form optical parts have been more and more widely used in military and civilian products. For these optical parts, which are mostly made of hard and brittle materials such as ceramics, optical glass, and hard alloys, super Precision grinding technology is an effective solution for its preparation. Commonly used forming grinding methods for optical parts mainly include vertical grinding and parallel grinding. The vertical grinding method uses the top of the V-shaped grinding wheel or the abrasive grain layer in the center of the arc-shaped grinding wheel to grind the workpiece according to the formed numerical control trajectory. This pr...
