Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] The method for visual real-time monitoring of the surface quality of the cylindrical grinding workpiece of the present invention, during the grinding process of the workpiece, the elastic contact between the grinding wheel and the workpiece, the rupture of the grinding wheel adhesive, the collapse of the grinding wheel abrasive grains, the friction between the grinding wheel abrasive grains and the workpiece, and the cracks on the surface of the workpiece can emit elastic waves. These factors are closely related to the workpiece material, grinding conditions, and the state of the grinding wheel surface. The change of these factors will inevitably cause changes in the amplitude of the acoustic emission signal, which allows us to judge the grinding state by detecting the change of the acoustic emission signal. The change range of AE signal is prop...

Abstract

The invention relates to an outer circle grinding workpiece surface quality visualization real-time monitoring method, which comprises the following steps of: 1, arranging an acoustic emission sensor and acquiring data; 2, preprocessing an acoustic emission signal; 3, establishing a roughness relationship model between the root mean square (RMS) of the acoustic emission signal and the workpiece surface; and 4, realizing the visualization of the workpiece surface quality in the grinding process. The outer circle grinding workpiece surface quality visualization real-time monitoring method can realize the visual real-time monitoring of the workpiece grinding quality by using the acoustic emission signal, provides help for guiding a grinding machine operator to select technological parameters, and has significance for improving the grinding efficiency and the grinding quality.

Description

technical field [0001] The invention relates to a method for real-time monitoring of precision machining, in particular to a method for real-time monitoring of surface quality of cylindrical grinding workpieces. Background technique [0002] In the ultra-precision / precision grinding process, how to monitor the surface quality and grinding condition of the workpiece in the grinding process in real time will be of great significance to improve the grinding quality and grinding efficiency. If the real-time monitoring of the grinding quality of the workpiece surface can be realized, the feedback control of the grinding process parameters can be realized, thereby realizing the intelligent control of the grinding process. Therefore, real-time monitoring of workpiece surface quality during grinding is the key technology of precision grinding technology. Although many researchers have done a lot of research work on grinding state monitoring technology using motor current, grinding ...
