Description
Summary:Vibration signals from various metal cutting processes in a frequency range of a few Hz to several MHz have been investigated by many researchers for their possible application to an in-process cutting condition monitoring system and some remarkable laboratory results have been reported. In spite of many very interesting demonstrations of feasibility in laboratories, numerous attempts to apply the technology to manufacturing conditions have not been very successful. The main objectives of this review are to summarize the key points of various published reports and to discuss the critical technical issues which are hindering transformation of the laboratory results to more broadly applicable technology. The vibration signals from metal cutting processes contain very useful information and offer excellent possibilities for in-process diagnosis of many critical metal cutting problems, including tool wear. The current state of knowledge still consists mainly of empirical observations, many of which need further clarification. Some of these key issues requiring future studies, particularly those issues related to in-process monitoring of tool wear, are discussed. 35 ref.--AA(UK /US).
