Abstract

The invention discloses an efficient multi-scale recognizing method for milling tool injuries and belongs to the technical field of milling tools. The objective of the invention is to solve the problem that the existing milling tool injury recognizing method does not carry out multi-scale considering on the milling tool injuries but focuses on micrometer and above macroscales. The method comprisesthe following steps: step a, carrying out scale division on the recognizing data of the milling tool injuries; step b, establishing milling tool structures and working load feature models; step c, carrying out measurement and recognition on the permanent deformation of milling tools; step d, analyzing the stress fields of the milling tools and recognizing partial injuries; step e, recognizing thematerial organization structural injuries of milling tool components; step f, recognizing the mesoscopic injury forming of the milling tool components; and step g, carrying out multi-scale recognition and experimental verification on the milling tool injuries. The efficient multi-scale recognizing method for the milling tool injuries can effectively recognize the milling tool injuries from multiple layers and overcomes the limitation of the existing macroscopic scale recognition for milling tool injuries.

Description

technical field [0001] The invention relates to a milling cutter damage recognition method, in particular to a multi-scale recognition method for high-efficiency milling cutter damage, and belongs to the technical field of milling cutters. Background technique [0002] In the new stage of modern cutting technology characterized by high-speed and high-efficiency cutting, due to the lack of manufacturing resources and increasing production costs, and the pursuit of higher utilization of manufacturing resources, high-speed cutting tool technology is developing in the direction of high-efficiency cutting tools. High-efficiency milling cutters developed on the basis of high-speed milling cutter technology have achieved excellent cutting effects with low energy consumption and low tool wear rate, and have attracted widespread attention at home and abroad. The high-efficiency milling cutter developed by the lightweight design method has the common characteristics of various high-ef...
