Processing progress information collecting method based on stress state of machine tool cutter

Abstract

The invention discloses a processing progress information collecting method based on a stress state of a machine tool cutter, and belongs to the technical field of manufacturing informatization. The method includes the steps of obtaining stress information of the machine tool cutter through a three-way measuring cell and a data collection card firstly, then extracting morphological filtering of an original stress signal and characteristic elements of processing progress in the methods of time domain analysis, frequency domain analysis and wavelet analysis, and ultimately identifying processing progress characteristic signals in a classified mode through a classification trainer of a support vector machine (SVM) so as to achieve collecting of processing progress information. The method can be widely used for manufacturing workshops and can promote development of the technique of internet of things in the workshop manufacturing process.

Description

technical field [0001] The invention relates to a method for collecting processing progress information based on the force state of a machine tool tool, and belongs to the technical field of manufacturing information technology. Background technique [0002] As a general-purpose equipment for mechanical processing, machine tools have always played an irreplaceable role in the machinery manufacturing industry. In the process of promoting networking and informatization, the problem of data acquisition at the bottom of machine tools has become the main problem in the implementation of workshop information systems. The processing progress information of the workpiece is one of the main data of the underlying production data of the machine tool, and the processing progress information of the workpiece is even more important information to support the management and optimization of the manufacturing process. The processing progress information of the workpiece includes many aspect...
