Abstract

The invention provides a method for laser turn-milling compound machining of a tool. The method for laser turn-milling compound machining of the tool includes the following steps of S1, measurement, S2, programming, S3, clamping, S4, laser turning for removing blanks, S5, laser turning of outer circle contour for molding, S6, laser milling of a profile, and S7, laser cutting. According to the method for laser turn-milling compound machining the tool, laser turning machining of the tool contour and milling machining of the tool profile are realized through one clamping, a traditional machiningtechnological process of the tool is subverted, and the problems of low machining efficiency, high machining cost and affecting machining precision and quality caused by requiring multiple processes for multiple clamping in the traditional machining process of the tool are solved.

Description

technical field [0001] The invention belongs to the technical field of cutting tool laser processing, and in particular relates to a method for laser turning and milling compound processing cutting tools. Background technique [0002] In recent years, with the rapid development of modern industry, in order to meet the high-efficiency and high-quality processing requirements of difficult-to-machine materials in key fields such as aerospace and 3C, the shape of tools tends to be complex, and the requirements for tool precision and quality are higher. Using traditional methods such as grinding to manufacture complex superhard material tools requires customized grinding wheels, and the process is complex, with high manufacturing costs and low processing efficiency. Laser processing has the characteristics of non-contact, flexible processing, and no material selectivity, and has become an important means to replace traditional tool manufacturing methods. [0003] However, at p...
