Abstract

The invention relates to a cutter wear monitoring method and system. The method comprises the following steps: constructing an initial cutter virtual model corresponding to a target cutter system; obtaining test data through a cutting machining test of the target cutter system; based on historical attribute data, historical command data, historical state data and historical wear data in the test data, correcting the initial cutter virtual model to obtain a target cutter virtual model; training a preset initial cutter wear monitoring model based on historical state data and historical wear data in the test data, and performing iterative training in combination with a theoretical wear result output by the target cutter virtual model to obtain a target cutter wear monitoring model; obtaining current attribute data, current command data and current state data of the target machining scene, and determining the actual wear condition of the current cutter based on the target cutter virtual model and the target cutter wear monitoring model. The accuracy and efficiency of cutter wear monitoring can be improved.

Description

technical field [0001] The present application relates to the technical field of automatic monitoring of CNC machine tools, in particular to a method and system for monitoring tool wear. Background technique [0002] In the field of manufacturing and processing, cutting tools are the key components of computer numerical control machine tools (CNCMT). Therefore, cutting tools have a great impact on the quality of processed products and the safety of CNCMT, and cutting tool wear mainly affects its cutting performance. Therefore, the wear of cutting tools Accurate monitoring and prediction can not only improve the machining accuracy of workpieces, but also reduce production costs. However, due to the complexity and time-varying nature of cutting processes, it is still difficult for traditional methods to achieve accurate real-time supervision. [0003] With the development of material science, difficult-to-machine alloys are gradually used in the manufacturing industry (especi...
