Laser deposition additive/subtractive hybrid manufacturing process for stainless steel powder based on DMG MORI LASERTEC 65 3D. On ensuring the precision of the workpiece, the one-time forming of the difficult parts such as the flange drilling and the joint production can be realized, the efficiency is 5-8 times higher than that of the traditional processing method.Īdditive/subtractive hybrid manufacturing stainless steel powder laser directed energy deposition shaping microstructures mechanical property Using DMG MORI LASERTEC 65 3D composite machining center, the composite machining of stainless steel special type turbocharged shell by powder laser direct metal deposition and 5 axis milling can be completed. The tensile strength and elongation reach 632 MPa and 46.9% respectively, which are comparable with forgings. The results show that the ideal equiaxed grain structure can be obtained by powder deposition and lap joint under the optimized laser forming conditions with the laser power of 2 400 W, the scanning speed of 1 000 mm/min, and the powder feeding rate of 14 g/min. The machining capability level and the application space of the DMG MORI LASERTEC 65 3D for the additive/subtractive hybrid manufacturing of the metal alloy components were also investigated. Optimizing the deposition parameters and determining the mechanical properties of the integrable parts were also performed. The effects of laser power, scanning speed and feeding speed on the section shape, size and surface roughness of stainless steel deposits were studied. Abstract The rapid preparation of the final quality parts using stainless steel powder was performed on the DMG MORI LASERTEC 65 3D, the first additive/subtractive hybrid manufacturing machine tool in China. ![]()
