Using a grinding process with a pre-formed wheel is an effective way to finish a relatively large batch of parts. Grinding wheels can be prepared with complex forms for finishing 3D-printed Inconel 718 and titanium 6-4 parts. The advantages can become more substantial for difficult-to-machine materials commonly used in 3D printing, because the self-sharpening property of abrasive grains extends abrasive tool life longer than that of other cutting tools. Compared with machining such as milling and other alternative finishing processes, grinding has advantages for producing tight tolerances, fine finish and desired compressive residual stress in the ground surface layer. Abrasive finishing, including grinding and polishing, has the capability to finish conventional as well as parts made additively - that is, 3D-printed parts. Or metal production parts made through additive manufacturing (AM), post-process finishing is often required, especially on functional surfaces.
