Hi everyone,
I'm having a bit of an issue with regards to doing a Best Fit alignment to align a fixture, specifically the fixture datums (4-Way, 2-Way, A-Nets).
I like to start off my alignment with Iterative first off of the tooling bushings built into the fixture base,
Then I proceed to measure the datums in DCC, then I will proceed to create another Iterative alignment off of the datums if possible,
else I will do a Best Fit 3D using the datums and save my alignment to be recalled in another program.
I'm noticing that after I run the program the datums are sometimes out of spec. after BF3D,
taking a closer look I can see my Best Fit alignment needs to be re-computed! (it's even lost it's chosen directions).
Is there a way to set the Best Fit alignment to auto compute every time I run the program,
or is it rule of thumb that after performing an Iterative in DCC, that the best fit alignment always needs manual intervention?
My program is basically this:
1. Pick up 3 tooling bushings manually
2. Iterative pick up off of the same 3 tooling bushings using DCC
3. Measure datums in DCC (4-Way / 2-Way / A-Nets)
4. Create BF3D off of the datums
5. Re-measure datums to make sure they are in spec. within +/- 0.05 mm
Thanks for any help you guys can provide,
I don't want to have to re-compute manually every time I run my external alignment program.
