Abstract

The invention discloses a metal part manufacturing system and method adopting micro-casting and laser shock texturing, and belongs to the field of metal part manufacturing. The system comprises a micro-casting module, a laser shock texturing module, a five-axis linkage workbench and a control device, wherein the micro-casting module is connected with the laser shock texturing module through a machine tool spindle, a double-axis position changing mechanism of the five-axis linkage workbench is located below the micro-casting module and the laser shock texturing module and used for containing ato-be-formed metal part, and the control device comprises a detection device, and is connected with the micro-casting module, the laser shock texturing module and the five-axis linkage workbench. Theprocesses of micro-casting and laser shock texturing are compounded for metal part machining and manufacturing, the problems that during metal part additive manufacturing, internal defects exist, thestructure property is poor, and the toughness and other mechanical performance are poor can be solved, and the metal part manufacturing system and method are suitable for machining high-performance complex components.

Description

technical field [0001] The invention belongs to the field of metal part manufacturing, and more specifically relates to a metal part manufacturing system and method for micro-casting laser shock texture. Background technique [0002] The traditional manufacturing process of metal parts is mainly through casting or forging, combined with turning, milling, grinding and other mechanical subtractive processing to obtain parts that meet the quality and precision requirements, but there are problems such as long processing cycle, low material utilization rate, and high manufacturing cost. [0003] Additive manufacturing technology is based on the principle of discrete-accumulation-control and uses the method of accumulating materials layer by layer to manufacture parts. Metal additive manufacturing technology does not require molds and can be directly formed according to the three-dimensional model of the part. It has the characteristics of high efficiency and low cost. Because of...
