Problems solved by technology

[0003] After searching the literature of the prior art, it was found that the Chinese patent application number: 99814313.8, the title of the invention is: control method and grinding machine for workpiece grinding process, this patent relates to a method for process control during rough grinding of workpiece, according to During grinding, the measuring sensor is used to measure the actual size of the workpiece and is continuously and automatically corrected to the predetermined rated size related to the grinding time according to the measured actual size. However, since this method uses the measuring sensor to perform contact measurement on the workpiece, The precision is low, and only rough grinding of rotary parts can be realized, so precision grinding of various complex curved surfaces cannot be realized

Embodiment Construction

[0014] The following examples are provided in conjunction with the content of the method of the present invention:

[0015] This embodiment is adopted in Shanghai's key scientific and technological research project - digital precision curve grinding technology and equipment based on image online recognition and detection. The control platform used in this embodiment mainly includes an eight-axis four-linkage CNC grinding system, a grinding wheel reciprocating motion control device and a CCD image measurement device. Eight-axis four-linkage CNC grinding system mainly includes industrial PC, motion control card, servo motor, servo amplifier, operation panel and machine tool control electrical appliances, etc. The motion control card adopts the latest open multi-axis motion controller TurboPMAC from American Delta Tau Company, which can control eight servo axes at the same time, and forms a CNC system with NC embedded in PC structure together with industrial PC. Among the eight ...

Abstract

A control method for the digitalized precise curve grinding includes such steps as creating the man-machine interface shared by computer and CCD screen, automatic precise regulation to reciprocation of abrasive disc, acquiring and processing the image of workpiece and abrasive disc, and in-line real-time compensation to abrasion of adrasive disc.

Description

technical field [0001] The invention relates to a digital precision curve grinding method based on image online recognition used in the technical field of mechanical processing, in particular to a control method for digital precision curve grinding. Background technique [0002] Precision curve grinding technology is mainly used to process various precision and complex molds (such as convex and variable ellipse non-circular rotary surface masters, profile forming wheels and rolling wheels, precision punches, precision templates for machining pistons of automobiles and car engines etc.) and tools (precision flat and circular tools, etc.) and various complex surface parts. With the rapid development of digital optoelectronic technology, replacing the traditional optical system with CCD technology will greatly improve the technical performance of precision surface grinding machines. The high-precision CNC600Xplus 6-axis tool grinding center researched and developed by Rollomati...
