Hi guys,
My names Glen, I'm operating a DEA with DMIS 2015, I'm UK based and very fresh to the quality department (Apprentice). Apologies for this not being DMIS specific, should be an easy one for someone no doubt.
The 1st image shows the drawing plan view of the part I'm working on, 2nd cross-section A-A (Plan view from the machines perspective when the part is on bed). I'm going to be working on the part with it laying along the X axis (On one of the faces which calls for a flatness tolerance), which means I intend to be working in the Y minus workplane during alignment; I'm doing this so I can hopefully achieve all measurements in one program. So, my first thoughts for alignment were the following:
Take hits on the front face, level Y minus, translate Y plus.
Take hits around Datum A, translate X, Z.
Measure and construct a line between top holes, X plus direction, so rotate X plus to line about Y minus.
The problem and question for me is then in doing so I'm not including Datum B. It's necessary to include it, but in doing so I would have to include probe rotations...? Would I be better to use the above alignment in the manual alignment to establish the part, and go ahead and use Datum B and rotations in DCC. I feel like I don't fully understand, perhaps being able to visualise, what I'm trying to achieve with alignment, the resulting trihedron etc. YET (Despite reading and seeing many useful posts, articles etc).
Thanks a bunch,
Glen.
