I received one part to measure in CMM with PCDMIS platform, and I am bit confused to alignment strategy on this.
Attached drawing snap for your understanding
Here Datum A is bottom face, Datum B represented to 4 holes.
In program I followed by below steps
The part is in XY plane
- Measure datum A
- Measure 4 holes
- Connect holes 1 & 4 with Line 1
- Connect holes 2 & 3 with Line 2
- Intersect Line 1 & 2 and get a IntPoint
- Construct MidPoint between holes 2 & 4
- Datum A - Spatial alignment in Z
- MidPoint - Planar alignment in X
- IntPnt - Origin XY
My concern,
- Is my alignment strategy is correct? please suggest
- How we can apply MMC to B datum?
I need help on this please
Thanks
