Re: Interpretation of surface finish specification.
Hi James,
Thanks. This parameter is asked in Aerospace industry (on HVOF Ground parts). how to achieve this The Drawing requirement is Ra,Rp,Rt & RMR (C0 5% Rz, C1 25%Rz).
The process is like this, HVOF Coating, Grinding, Superfinish. We are able to achieve Ra,Rp,Rt only RMR is difficult.
The equipment setting is giving two Rmr's & which is the correct value which we should consider to meet the drawing requirements.
