  • Alignment problem

    How can I align with two plane for datum A and datum C and a hole for datum B as origin ?

  • Need Help with Part Alignment

    I could use some help to determine the validity of my alignment for checking a clevis in a fixture. I have a picture of the clevis mounted in the fixture attached to this post. The three work planes that can be seen in the picture are Z+, X- (clamped…

  • Programming with Die Pull degree callouts

    I have been trying to write a program for a part and have noticed that my part print nominals aren't matching up with my CAD nominal. After looking closely at the part print, I noticed a direction arrow and a die pull arrow with a degree called out. This…

  • Core Pin alignment

    Hello, this is my first post and I just have a basic experience with CMM's and PC-DMIS. I am having a hard time figuring out how to align a core pin (see picture below). I have the .IGS model uploaded and I tried to align the part using a cone and…

  • Help aligning to a part (yes, another one of these posts)

    Hey guys, I've been trying to align to this part for the better part of today and I'm coming up with nothing. Best fits using anywhere from 6 to 19 points end up with T values varying upwards of .100" across the side edges (the critical feature…

  • Problem with CAD/RPS Alignment

    Hello, I'm fairly new to CMM programming with CAD models, I just started a month ago and I haven't had any major problems until now. I have to say that I never had a proper formation on CMM programming at all, I learned everything I know by my own. …

  • Manual vs DCC alignment

    I have taken the basic 1 week PCDMIS course from Hexagon. Currently I have only modified part programs written by the programmer at our parent company location to run on our cmms. I work with version 3.7 on cmm 2 and 2014 on cmm 3. Cmm 1 has…

  • A-c datum alignment

    Opinion needed: Was wondering if it was possible for one of these holes (dat-c-) to give good t.p readings. Since the parts is symmetrical all 3 holes should be used with dat-a- for an alignment (a-c in feature control frame). So it would be possible…

  • Update dependant commmands prompt is not appearing

    PC DMIS 2014.1 X64 Build 767 Service Pack 2 When changing or adding an alignment the update dependant commands prompt is NOT appearing. This is on both the CMM and the offline station Looked in the setting editor at the Update Below Changed Alignment…

  • Measuring like features on a cyilndrical part

    Hello All, I have a cylindrical part that has 6 identical milled pockets clocked 60 degrees along the length of the part. Three pockets (making one set) is milled 6" from the end of the part 120 degrees apart at (12/4/8 o'clock). Another three pockets…

  • Upside-down Alignment

    Hey guys. I'm trying to do an iterative alignment on a fixture but I'm hitting a speed bump and I'm not sure whats causing it. The points for the manual alignment are identical to the automatic alignment and share all the same properties. The manual alignment…

  • Lack of confidence in CMM

    I've been using the CMM for a about 4 years now in a job shop. We only use it when we *need* to (when we need to produce an inspection report for the customer). I'm the only CMM operator. Running 2012 MR1 CAD. I have several parts that I need to inspect…

  • Fixture moved

    Hello, I will just get right to the point. I had to make my fixture higher up off the stone. I have already made the program. But, now that I have moved the fixture, when the program gets to DCC mode, it keeps going back to where the fixture was. How…

  • Alignment Issues

    Afternoon, I've used the search function here but cannot seem to find anything related to my issue. Before I get into the issue I will say I have 0 formal training using PC-DMIS, I've had to ultimately self teach my self how to run this machine…

  • Alignment Rotation Problem

    Hello, I have a strange problem with doing Alignments, I can't rotate with offset angle when using Alignment Window. The field offset angle is shaded. It's working ok when typing in but it's a bit annoying and time consuming. We're running 2013…

  • Deleted alignment after program was made

    I DELETED AN ALIGNMNET USED FOR MY PART, AFTER I MADE MY PROGRAM AND THEN CONTRUCTED A NEW ONE. IT WILL CHECK MY DATUMS A,B,C, (the alignment) BUT NOTHING AFTERWARDS. DOES ANYONE KNOW OF A WAY TO "MERGE" THE PROGRAM BACK TOGETHER? OR SHOULD I START OVER…

  • DRF & XYZ alignment not merged together

    Morning to all, I've written some simple programs before and noticed the DRF and the x,y,z, in the display window typically merge when the alignment and datum definition is done correctly ( this was using only one simple a,b,c, construction. Is it…

  • Can a centerline be contructed and used as a tertiary datum?

    Hello all I'm wondering if a centerline can be constructed from a basic dimension and utilized to make a centerline to make as datum C. Datum A is the face of the part that will mate with another in assembly ( the most critical) Datum B is a plane perpendicular…

  • Equate Alignment program problem

    I have a part program, i have successfully written it to where i can flip the part, and equate the alignment, all works well, until the next part is ready to be measured. I cannot get the Dmis to go back to the startup alignment at the beginning of the…

  • First time using B-C as a tertiary datum

    Had just a quick question, it seems it may be as elementary to most on this forum about a B-C Tert. Datum I need to know for sure if I did this correctly. I have a flat part with datum A as the plane which I leveled and origin in Z I have a center…

  • need help with an alignment

    hello everyone I have a gage I need to measure but cant seem to figure out how to do the alignment. I cant use a 3-2-1 alignment because the CAD model doesn't match the part, which is fine but I cant seem to get this figured out. I start off by leveling…

  • Old problem and again I struggle...CAD, Cyl shaped part, alignment

    I have a part that basically looks like a Gauge Pin with a hole drilled thru it (90 perp to the longitudinal axis of the cyl). I am having a very difficult time trying to get this thing aligned using CAD. I have tried 3 points on one of the flat ends…

  • Offset Alignment, Dimension T not work?

    Hi! We have measured a detail in fixture and now we want to move the reference holes in the detail to see if it can make it better. Now we have offset the alignment as we should move the holes, just to see what it makes before we change it physically…

  • Multiple parts with same alignment

    First time here, I looked around for quit a while and could not find anyone with the same question. I am very new with the cmm (I took the Hexagon lvl 1 course and thats pretty much it... though i was by far the fastest learner there due to my cad experience…

  • Alignment Method Question

    Hello, I come across a lot of these exhaust parts and have not always been 100% confident in the alignment methods I have used. For this part, the customer has specified the flat area around the hole as the A datum, the hole as the B datum, and…
