Abstract

The invention discloses a cutter online monitoring system and method. The system involves an intelligent clamp, wherein the intelligent clamp comprises a clamp body, a clamping module, a sensor, and an isolation module; a to-be-cut workpiece is placed on the clamp body, the sensor is embedded in the clamp body, and the isolation module is used for isolating external interference; the cutter onlinemonitoring system further involves a data acquisition module, a shielded wire and an intelligent processing module, wherein the data acquisition module is used for acquiring current machining parameters of the to-be-cut workpiece, and the sensor transmits a current machining signal to the intelligent processing module; and the intelligent processing module comprises a machine learning model, judges whether a cutter is broken or not and wear degree of the cutter through the model and predicts the service life of the cutter through the model. By means of the cutter online monitoring system, intelligent monitoring during cutting of the part in the machining process can be achieved under the condition that external environment interference is prevented, and the monitoring precision can be improved through the machine learning model, so that accurate monitoring of the cutter is achieved.

Description

technical field [0001] The invention relates to the fields of on-line monitoring of mechanical processing and intelligent manufacturing, in particular to an on-line monitoring system and method for tools. Background technique [0002] Tool breakage and uncontrollable wear in the machining process seriously affect the efficiency and machining accuracy of machining, and more seriously will cause damage to the workpiece and the machine. Various physical signals are generated directly or indirectly during the cutting process. [0003] In recent years, various companies and research institutions have carried out corresponding principle research and application research, such as foreign countries such as ARTIS (a German company), MONTRONIX (a German company), DIGITWAY (a foreign company), domestic companies such as Geelandin, Huazhong Enterprises and universities such as University of Science and Technology, Northwestern Polytechnical University, Harbin Institute of Technology. ...
