Monitoring of selected process variables during the CFG grinding

Abstract

The grinding process is often used as a roughing operation for materials difficult to machine (the process CFG). Simultaneously the end result is dependent on a large number of different, difficult to measure on-line parameters. Because of the significant cost of workpieces significant issue becomes the problem of monitoring this process. The presented research are to determine capabilities of using to that selected process variables of measuring signals. In this the acoustic emission, current of grinding spindle, vibrations and grinding force signal were used. They were then evaluated for capabilities to use in the system for monitoring the CFG process. The end results of the process were determined by measuring the roughness parameters and the lack of thermal damage on the surface.
