Abstract

The invention discloses a hard and brittle material laser assisted machining method of laser modified ultra-precision cutting, relates to a laser assisted machining hard and brittle material methods,in particular to the hard and brittle material laser assisted machining method of laser modified ultra-precision cutting, and belongs to the field of machining. In order to solve the problems that atpresent, laser auxiliary turning only can be applied to cylinder face turning, local focal points and cutting areas are placed in the same circumference face, and the geometric position relation of atool and the laser focal points cannot be kept constant, the method comprises the steps of firstly, setting up a laser auxiliary cutting platform; secondly, focusing a continuous laser beam generatedby a laser output head on a workpiece surface; and thirdly, using a tool for cutting the modified workpiece surface.

Description

technical field [0001] The invention relates to a method for laser-assisted processing of hard and brittle materials, in particular to a laser-assisted processing method for laser-modified ultra-precision cutting of hard and brittle materials, which belongs to the field of mechanical processing. Background technique [0002] Hard and brittle materials such as cemented carbide, ceramics, and glass have important application value and broad application prospects in the fields of aviation, optoelectronics, and medical treatment. The key components made of these materials are compared with Compared with traditional parts, the service life and ability to resist extreme conditions are greatly improved. However, these materials generally have greater processing difficulties, such as higher hardness, lower fracture toughness, etc., which will cause greater wear and tear on the tool during processing, which has brought greater challenges to traditional machining methods. difficulty....
