Abstract

Since chip shape directly affects the normal running ofthe automatic machining system, such as CNC, FMS, CIMS and so on In order to ensure their normal running, the supervision of tool cutting state was necessary and significative research task. In this paper, we analyze the method ofindirectly supervising chip shape by signal changing, for example cutting force, cutting temperature, Acoustic Emission, ray-electronic signal and sound signal when chip effuses out etc. and point out their flaw in theory or application and bring forward chip recognizing method based on chip shape features. The differentiate method according to gray-scale of chip image, can get chip shape feature what need by setting appropriate value. Then the feature is extended and transformed and get new shape feature. Finally recognize chip shape by calculating euler number of new feature. This paper puts forward recognizing theory's algorithm and develops computer program. The method can recognize typical cutting chip, such as "C" chip, spiral chip and abnormal chip and was proved to have a good precision by recognizing chip experiment in practical machining.
