The state of machining process monitoring research in Korea

It is well known that machining process monitoring is a crucial requirement in the successful implementation of the automated/unmanned operation of a plant, also referred to as FMS, CIM, CAPP, etc. This necessity has been rec ognized by many researchers in Korea and many encouraging results have been reported, despite the relatively short time that this area has been resear ched. This paper is intended to offer a comprehensive review of the current state of machining process monitoring research in Korea. Research concerni ng the monitoring of such machining states as chatter, tool fracture and we ar, built-up edge, chip type, runout, etc. is included. General diagnostic techniques will be discussed to some extent. Sensors used to monitor machin ing processes will be investigated first, followed by signal processing met hods and decision-making algorithms. In the process, some of the significan t Korean research will be introduced in some detail, while other research w ill be described briefly for each category of machining state.
