WebJan 29, 2024 · Sometimes, a process has specifications that are one-sided such as flatness, perpendicularity, surface finish and roundness. When assessing process capability in those cases, you will actually be looking at the process capability for one half of the distribution – the half that’s not cut off by the boundary specification. WebSep 3, 2024 · The acceptance of the machined surfaces not only depends on roughness parameters but also in the flatness deviation (Δ fl ). Hence, before reaching the threshold of flatness deviation caused by the wear of the face mill, the tool inserts need to be changed to avoid the expected product rejection.
