Abstract

The invention belongs to the technical field relevant to tool abrasion detection and discloses a milling tool abrasion monitoring method based on data. The method comprises the following steps that (1) a three-phase output current signal of a spindle driving motor of a numerically-controlled machine tool during working of a milling tool is collected; (2) the collected three-phase output current signal is cleaned; (3) a characteristic coefficient representing milling tool abrasion is extracted from the cleaned three-phase output current signal through a compressed sensing method and the key point theory; and (4) a characteristic signal index is computed online according to the three-phase output current signal, collected in real time, of the spindle driving motor when a certain milling tool works normally, and thus milling tool abrasion is subjected to real-time online monitoring. Through the provided milling tool abrasion monitoring method based on the data, the cost is lowered, and real-time monitoring of milling tool abrasion is achieved.

Description

technical field [0001] The invention belongs to the technical field related to tool wear detection, and more specifically relates to a data-based milling tool wear monitoring method. Background technique [0002] At present, with the development of computer and automation technology, the field of mechanical processing is developing towards the direction of intelligent manufacturing. The most basic requirement of the manufacturing and processing system is that the processing system can automatically and effectively monitor and adjust the faults that occur during the production and processing process. The wear of the basic element tool in the machining process will cause the vibration of the machine tool, the decrease of the surface quality of the workpiece and the accuracy of the machining dimension. Therefore, the research on the feature extraction of tool wear is of great significance for the monitoring of tool conditions. [0003] Over the past few decades, machining cond...
