Problems solved by technology

[0003] However, metal parts manufactured by laser selective melting generally have problems such as surface roughness and dimensional deviation. Usually, after forming, traditional machine tools must be used to mechanically process key positions before they can be put into practical application, resulting in prolongation of production cycle and manufacturing cost. the climb

Abstract

The invention discloses material increasing and decreasing composite manufacturing equipment and method for metal part. The material increasing and decreasing composite manufacturing equipment comprises a material increasing manufacturing assembly, a material decreasing manufacturing assembly, an atmosphere regulating and controlling assembly and a control system. The material increasing manufacturing assembly is used for conducting laser selective melting on the to-be-machined part. The material decreasing manufacturing assembly is used for conducting machining on a molten-formed metal part slice layer. The atmosphere regulating and controlling assembly is used for providing protective gas for a laser irradiation area during part manufacturing and for clear away metal smoke dust generated by the laser irradiation area. The control system is used for treating a to-be-formed metal part CAD model, for generating the machining tracks of the material increasing manufacturing assembly and the material decreasing manufacturing assembly, and for driving all parts of the equipment to operate. Through application of the material increasing and decreasing composite manufacturing equipment and method for the metal part, metal parts which have various size precision, good surface quality and complex structures can be manufactured once efficiently.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and in particular relates to a compound manufacturing equipment and method for adding and subtracting materials of metal parts. Background technique [0002] Laser selective melting is an emerging additive manufacturing technology, which is based on the principle of "discrete-accumulation", using the high-energy-density laser beam output by the scanning galvanometer to carry out selective melting on the metal powder layers laid layer by layer. Complete near-net shape of complex metal parts without fixtures and dies. [0003] However, metal parts manufactured by laser selective melting generally have problems such as surface roughness and dimensional deviation. Usually, after forming, traditional machine tools must be used to mechanically process key positions before they can be put into practical application, resulting in prolongation of production cycle and manufacturing cost. c...
