Capability & GDT Features - Surface Profiles, Line Profiles & Symmetries
Ok, I have read a few threads on the forumn but feel I need my own thread.
We have been asked to measure Surface Profiles, Line profiles & symmetries on injection moulded components. All have a unilateral tolerance ie 0-0.1mm.
How do we correctly upply capability to these? Currently we are using MiniTab to calculate a PPU value, only having an upper boundry. Our customer has queried this thinking we should be using 0 +/-0.05mm.
Any views on this?
