The monitoring of cutting conditions is one of the most important techniques in the machining process (turning, milling, etc.). In these machining processes, milling is more difficult to monitor than turning because two or more cutters engage in cutting at the same time and a sharp change in cutting force causes vibration of the workpiece. In this paper, we test several techniques to detect chatter, built-up edge and tool fracture under varying cutting force conditions which we find in milling. This paper describes of the following : (1) monitoring of the quasi-static cutting force ; (2) detection of the air-cutting period using an autoregressive time series model ; (3) monitoring of the envelope of the dynamic cutting force. Finally, we propose effective monitoring techniques for varying cutting force conditions.
