I deal with injection molded plastic parts. Recently we have been issues with Bonus tolerances that are calculated on the demon PC-DMIS. For a hole measurement the Bonus is being calculated as 3.00mm. The same hole with the pin check on fixture passes, the Fixtures are certified and calibrated.
I use Romer arm (portable Scanner CMM) for the measurements. Any suggestions would be helpful. Is there any detour on PC_DMIS where I can override that Bonus.
Bonus tolerances are calculated as (actual - hole @ mmc).
You should check what tolerance you have given for that hole? Additionally, please check to see that the actual hole type is correct (inner, not outer) in the feature.
