I hired a new guy and he insists upon doing one DCC alignment and never doing another alignment, he lets the feature control frame control the alignment for him. I don't think that is a good practice, does anyone have an opinion on this?
I'd like to redact my previous statement.
Most of the time we measure parts (hydraulic valve spools, yay cylinders!) I create an alignment for every feature.
I have to align to the part itself, and I do this by zeroing on a circle, taking 4 more and level/zeroing to a cylinder, zero the Y, and zero W (the angle of the rotary table).
Each of these are done in seperate alignments, and then one final alignment to create the "Full DCC Alignment". This has to be done before any measurements can take place, and for most of my specific use cases, every 30° or so. So there are plenty of alignments going on, I just like that for posterity. Some of the tolerances are about ± .0001", with approximately 75 features with 3 to 5 dimensions each.
While this takes a long time, in my opinion
alignments are the most important aspect of metrology. I personally don't care if a part takes 5 minutes or 5 hours, as long as I'm measuring it right!
