2 2019-06-26 Grind to Finish: A Postprocessing Solution for Additive Manufacturing

摘要

摘要 |

HTML | 网页快照 | | 1次

The increased use of additive manufacturing (AM) in the aerospace and medical markets fosters a growing need to finish the surfaces of additive parts to meet final application requirements. Since the additive manufacturing process is capable of producing components close to near-net shape, there is often little stock that remains for providing final finish. This benefits the overall manufacturing process by reducing waste, but it also means that subsequent finishing processes have limited room ...
