摘　　要：采用选区激光熔化(SelectiveLaserMelting,SLM)快速成型设备与316L不锈钢粉末,得到的空间曲线啮合轮样品表面粗糙度值较大,主动轮与从动轮不能实现连续稳定的啮合传动。为了研究选区激光熔化成型的空间曲线啮合轮的表面后处理工艺,采用机械喷砂与电解抛光相结合的加工方法得到的主动轮与从动轮样品,表面粗糙度值达到Ra 1.0μm。实验结果表明,采用的后处理工艺和参数获得的主动轮与从动轮样品具有较高的形状精度与尺寸精度,能够实现连续稳定的啮合传动。此方法为空间曲线啮合轮提供了较好的制造思路。By using Selective Laser Melting Rapid Prototyping equipment and stainless steel powder,the surface roughness value of the SCMW（Space-Curve-Meshing-Wheel）attained is too large for the driv-ing wheel and driven wheel to meet the continuous and stable meshing transmission requirements.In order to study the post-processing technology of SCMW in selective laser melting,driving wheel and driven wheel samples are obtained through combing sandblasting with electropolishing with high surface roughness up to Ra 1.0μm,which experimental results show that the driving and the driven wheels samples obtained through this post-processing technology are satisfied with their higher accuracy in shape and size to achieve continuous and stable transmission.This method provides a good way for manufacturing SCMW.
