Problems solved by technology

However, at present, laser processing machine tools at home and abroad can only realize one-time laser processing of two-dimensional large-curvature curves, while for three-dimensional large-curvature lines, they can only be processed by splicing laser forming methods with small-curvature curves, resulting in laser processing of large-curvature surfaces. The problem of complex machining trajectory, low machining efficiency and poor machining accuracy

Abstract

The invention provides a large-curvature curved surface laser processing forming method. The method comprises the following steps that a laser processing program is written according to the shape andsize of a to-be-processed tool and the shape and precision requirements of a final tool, and a laser processing path is simulated; the to-be-processed tool is clamped to a center rotary table on a laser machine tool, and the to-be-processed tool is positioned through a probe; and the laser processing program is started, and tool three-dimensional large-curvature curve one-time laser processing forming is carried out through a five-shaft linkage mode among optical shafts of a laser galvanometer module and mechanical motion shafts of the machine tool. By means of the method, one-time processingforming of a large-curvature curved surface can be achieved, splicing processing forming of a traditional processing mode is avoided, a laser processing track of the large-curvature curved surface isgreatly simplified, and the processing efficiency and the processing precision can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a large-curvature curved surface laser processing forming method. Background technique [0002] In order to meet the high-efficiency and high-quality processing requirements for difficult-to-machine materials used in key fields such as aerospace and 3C electronics, the tool profile tends to be complex, and the requirements for tool precision and quality are also getting higher and higher. The manufacturing of high-performance cutting tools by traditional methods such as grinding and EDM is complex, with low processing efficiency and greatly increased manufacturing costs. It has been difficult to meet the manufacturing needs of high-performance cutting tools. [0003] Since laser processing has the characteristics of non-contact, flexible processing, and no material selectivity, it has great potential in the manufacture of complex-shaped cutting tools. Howe...
