Do away with manual alignments - use Readpoint

Butch
Hi Everyone
I am fairly new to PCDMIS being a Mitutoyo programmer for the last 10 years (Booo). The training I had on PCDMIS was reliant on a MANUAL setup before going into DCC mode. By going straight into DCC mode position your probe over its start point. Then you can insert a READ POINT. Then put the XYZ origin on the READ POINT and hey presto your probe has a X0, Y0 and Z0 starting point. You can now do a rough setup by getting the CMM mode to search for your part elements.
This can still then be skipped if not required for further parts. Why go to the lengths of manual probing when the CMM will do it for you?

I am enjoying the new challenge of PCDMIS and can see that it is deep and dark. By using code instead of set routines like the Mitutoyo I realise it can be a lot more flexible. Now if I only knew all the codeing tricks?
Please look out for my questions appearing.

  • So with this, did you put it in DCC Mode right away, insert an auto circle (CIR1), then put in the readpoint PNT1 above the circle, to the location of that circle?? Then PNT2 and CIR2, but what is the ALIGN3 at the end, is that an iterative alignment??

    Start in manual and let it pause at the operator comment while you position the probe. As soon as you dismiss the comment dialog execution continues, reads the current center of stylus position and keeps executing line by line. ALIGN3 is just a 2D bestfit alignment to split whatever deviations the 2 holes bring into the mix. Also, (the code doesn't include it) I would start with a large prehit value (0.3" or so) until the part is under control. Then lower the prehit to whatever you're comfortable with.
