Abstract

The invention discloses a laser composite manufacturing technology of parts. The laser composite manufacturing technology comprises the following steps: S1, loading a model; S2, preprocessing the model; S3, slicing; S4, performing a material additive manufacturing technology; S5, judging whether surface roughness meets the requirement or not; S6, carrying out laser remelting and laser polishing; S7, judging whether dimensional accuracy meets the requirement or not; S8, carrying out laser ablation and laser engraving; S9, judging whether surface quality meets the requirement or not; S10, carrying out laser quenching and laser oxidation; S11, judging whether the manufacture of the model is finished. The laser composite manufacturing technology integrates the laser material additive manufacturing technology, a laser material subtractive manufacturing technology and a laser surface modification technology, thus being capable of effectively improving the dimensional accuracy, surface smoothness and compactness of the parts, improving the surface quality of the parts, and realizing one-time molding of the parts.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a laser composite manufacturing technology for parts. Background technique [0002] The existing part manufacturing process cannot integrate laser additive, laser subtractive, and laser surface modification technologies, and in the process of additive manufacturing, it is also impossible to perform material subtractive processing and surface treatment on process features, which affects the manufacturing process. The dimensional accuracy, surface finish, compactness and surface quality of the parts. [0003] Therefore, the present invention provides a laser composite manufacturing method for parts. In addition to realizing the traditional laser melting technology, the laser wavelength, output type (continuous or pulsed) and laser focal plane are controlled by software according to the process requirements of the workpiece, so as to realize laser remelting, Laser processing...
