The method comprises the following steps: (1) monitoring a processing area by adopting a machine vision method to acquire real-time image characteristic information; and (2) carrying out grinding and polishing model removal processing and calculating on the real-time image characteristic information to output a predicated removal effect. The device comprises a machine vision system, a mainframe, a predicted removal software module and an auxiliary supportingmechanism. The method is high in automatic intelligent degree, and improves the processing precision and processing efficiency of a workpiece. By comprehensively considering the actual condition of the workpiece in the grinding and polishing processing process, the processing removal effect can be predicted in real time, so that the device and the method have positive guiding significance to grinding and polishing processing.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and in particular relates to a method for real-time prediction of the removal effect of the grinding and polishing process and a device for realizing real-time prediction of the grinding processing effect by using the method. Background technique [0002] At present, the common grinding and polishing method is shot grinding, but the traditional shot grinding has disadvantages such as low processing efficiency, high processing cost, unstable processing accuracy and processing quality. The fixed abrasive grinding technology solves these problems, which can not only ensure the precision and quality of the grinding process, but also significantly improve the grinding efficiency and reduce the processing cost. [0003] Since most of the grinding and polishing process is floating grinding, the general specific performance is that the movement of the abrasive tool is known, but the movement ...

AI Technical Summary

Problems solved by technology

Only using a specific speed or speed ratio to infer and predict the change of the workpiece surface shape over a period of time, there is a large error, and it cannot reflect the actual trajectory of the abrasive during the actual machining process

[0005] At present, the trajectory simulation is limited to the two-dimensional coordinate system, and the removal effect is simulated through the density of the two-dimensional trajectory line. When the trajectory line is relatively dense, the removal effect cannot be distinguished, and it has no practical application value.
