Design Process Control for Improved Surface Finish of Complex Parts

 

CRP year	2016
Budget	£40k
Project Reference No.	31494
Technical Lead	Mikdam Jamal
AM process & materials used	Powder bed fusion, laser (SS316L)

 

Summary

Surface finish of a metal AM part is uneven, with surface roughness being variable over the facets of the design. Furthermore, the surface quality achievable using standard post-processing methods is generally unacceptable for wider AM part uptake in some major industrial processes. The objectives of this project were to:

• Design based on process informatics to aid the user to select optimal production parameters for the generation of parts with a specified output surface finish and/or production cost.
• Obtain quantitative understanding of the capability and efficacy of mass finishing processes in delivering target surface finish over a range of part input conditions (focus on centrifuge, barrel and drag finishing).
