A Study on the Diagnosis of Cutting Tool States Using Cutting Conditions and Cutting Force Parameters (I) ABSTRACT The detection of cutting tool states in machining is important for the automation. The information of cutting tool states in metal cutting process is uncertain. Hence a industry needs the system which can detect the cutting tool states in real time and control the feed motion. Cutting signal features must be sifted before the classification. In this paper the Fisher's linear discriminant function was applied to the pattern recognition of the cutting tool states successfully. Cutting conditions and cutting force parameters have shown to be sensitive to tool states, so these cutting conditions and cutting force parameters can be used as features for tool state detection. Key Words: signal feature(신호특징), linear discriminant function(선형식별함수) cutting condition(절삭조건- cutting force parameter(절삭력 파라메타)
