Metal AM Process Informatics for Improved Surface Finish of Complex Parts

金属增材制造（AM）以接近净形状创建复杂的3D部件。增材制造零件的表面光洁度（SF）是不均匀的，表面粗糙度在设计的各个方面是可变的。使用标准后处理方法实现的表面质量对于一些工业部门增材制造零件的吸收是不可接受的。这里的挑战是通过减少增材制造过程中近净零件表面粗糙度的变化来改善金属增材制造零件的表面光洁度，并改进后处理（PP）技术以适应增加的增材制造零件复杂性。该项目旨在开发一种创新的工艺优化系统，该系统可以将增材制造参数与生产的表面光洁度联系起来，为增材制造设计师生成一个软件工具，用于选择最佳参数，为单个增材制造部件生成优化的表面光洁度，并随后优化后处理SF方法。这种方法将优化增材制造过程和asPP技术，以实现所需表面处理的交付，增加高价值增材制造零件的工业采用，增加销售和就业，同时支持英国制造业创新。

Metal additive manufacturing (AM) creates complex 3D components at near net shape. Surface finish(SF) of theAM part is uneven, with surface roughness being variable over the facets of the design. The surface qualityachievable using standard post-processing methods is unacceptable for some industry sector AM part uptake.The challenge here is to improve metal AM part surface finish by decreasing the variability of surface roughnessof the near net-part during AM production and to improve post-processing (PP) techniques to suit increasedAM part complexity. This project aims to develop an innovative process optimisation system which can link AMbuild parameters to the surface finish produced to generate a software tool for AM designers to use to selectthe best parameters to generate an optimised surface finish for the individual AM part, and subsequentoptimised post-processing SF methodologies. This approach will optimise both the AM build process as well asPP techniques to enable the delivery of the required surface finishes, increase industrial adoption of high-valueAM parts, generating increased sales and employment while supporting UK manufacturing innovation.
