Behavior Monitoring of Small-Diameter Milling-Cutter during High-Speed Milling

Abstract

In this paper, attempts were made to establish a system to monitor the behavior of small-diameter milling-cutters during high-speed milling, by using of visualization based on high-speed CCD camera. Experiments were designed to investigate the characterization of the cutter behavior during the high-speed milling. The image of cutter failure was caught successfully, and the characteristic image is found to be distinct before the breaking of the cutter. This can be used as an index to predict in process the cutter failure, and so the cutter breaking will be avoidable during high-speed milling. Experimental System and Image ProcessingExperimental System and Condition. The system includes machining center, CCD camera, laser sensor, trigger generator, light source and personnel computer, as shown in Fig. 1, where Fig. 1a shows the picture and Fig. 1b the signal flow.
