I am working on the design of a metal scanning mirror. From experience, and previous calculations, I know that fabrication is a more complicated requirement than vibration modes and stiffness while scanning.
I am trying to simulate the grinding process in FEA, using COSMOS. I have configured the mirror face as a roller/sliding restraint, and I am applying 10N force to the opposite side. This gives me a stress plot that I am trying to make sense out of.
Is there some way to estimate how much material is removed for a given normal stress?
Has anybody analyzed anything like this?
I am looking for flatnesses within [λ]/1, which is about 633nm, across a 91x53mm mirror.
