Description

technical field [0001] The invention relates to contour image recognition and coordinate extraction of basic parts of forming bins of selective laser melting (SLM) forming equipment, in particular to a positioning image acquisition device and method of SLM composite manufacturing basic parts. Background technique [0002] Traditional machining has the advantages of fast processing speed and low cost, but it cannot process complex special structures and cannot meet the individual requirements of customers for workpieces. Selective Laser Melting (SLM) is one of the most promising technologies in the field of additive manufacturing (also known as 3D printing). This technology uses a high-energy-density laser beam to rapidly melt and solidify metal powder, forming parts with complete metallurgical bonding and a density close to 100%; this technology can form components with any complex structure, but compared with traditional machining, machining Long time and high processing c...

Problems solved by technology

This technology uses a high-energy-density laser beam to rapidly melt and solidify metal powder to form parts with complete metallurgical bonding and close to 100% density; this technology can form components with arbitrary complex structures, but compared with traditional machining, processing Long time and high processing cost

[0003] Some parts have both a simple structure and a complex structure; for example, the impeller has both a simple structure-a solid disc-shaped part and a complex structure-the blade part; if it is fully processed by traditional machining, the blade part is difficult to form and easy to deform , The processing cost is high; if SLM technology is fully used, the molding time and processing cost will be greatly increased; if the part is divided into two, the solid disc-shaped part is formed by traditional machining, and then the blade structure is formed by SLM on the solid disc-shaped part , which can realize high-efficiency and low-cost processing of parts
