Grinding wheel dressing method and device based on machine vision

Abstract

The invention relates to a grinding wheel dressing method and a grinding wheel dressing device based on machine vision. According to the grinding wheel dressing method, contour line information of multiple positions is obtained when the grinding wheel rotates; carrying out segmentation processing on the obtained contour line information to obtain a basic line segment; the maximum range of the basic line segments at the same position is used as the bounce of the working layer; according to the method, the bounce amount of the working layer can be accurately calculated, so that trimming is carried out according to the bounce amount, the bounce of the working layer is reduced, the contour precision of the grinding wheel is improved, the trimmed grinding wheel has a better grinding effect, canbe used for precision grinding and is beneficial to improving the stability of the grinding performance of the trimmed grinding wheel.

Description

technical field [0001] The invention relates to a grinding wheel dressing method and device based on machine vision. Background technique [0002] Grinding wheels are often used for grinding items, such as electroplated grinding wheels, ceramics, resins, metal grinding wheels, etc. Electroplated grinding wheels usually refer to the deposition of a single layer of abrasive grains and matrix metal on a steel substrate by electroplating, thereby manufacturing the working layer of the grinding wheel . Compared with superhard material grinding wheels such as resin, ceramic and sintered metal bonds, electroplated grinding wheels have the advantages of strong bond holding force on abrasive grains, high abrasive grain exposure, and large chip space for grinding wheels; in addition, with With the development of numerical control technology, the steel substrate can be made into various complex curved surfaces, that is, the outer circle of the electroplated grinding wheel can be made ...
