  • Profile surface datum definition

    I am trying to set the datum, but I wonder if there is a way to set the datum a when datum A is a curved surface as shown in the figure. version : pc-dmis cad++ 2018 r1 ​

  • Feature Set Profile Calculation

    I have a scan that is made up of six segments. Each individual segment is within a profile tolerance, but when I create a feature set of the six, the min value is out. How is the calculation different when it is a set? I figured it would just take the…

  • Iterative Alignment

    Hi Everyone! I am working with a forge part with no datum structure. It is calling for a profile of .120 u .09 to itself. (+.09/-.03). My though is that the simplest way to approach this is with an iterative alignment (machine to part),…

  • Legacy dimension - profile of a surface

    First of all, I am aware this topic has been covered, but my google-fu failed to find a solution for my current conundrum. All that follows is relative to PC-DMIS 2012 Part setup: Datum A: Cylinder along Z, locking X, Y and two rotational…

  • PC-DMIS 2020R2 – Profile ISO 1101

    Hi Rob Jensen & neil.challinor I would like to ask you about your opinion about this issue. We often have profile callouts similar to this |ꓵ|0.1 UZ -0.1| on our customer drawings, where both tolerance “borders” are on one side of the nominal…

  • How to place points exactly on center line

    I am trying to Probe a line right down the center of my part where the hits come in from the appropriate angles. I could make it from individual points or a line, but I don't have scanning capabilities. I have attached some pictures that should help you…

  • Radial seperation Value

    Hi All, As per the title, anyone heard about the term "Radial Separation Value" during a Sphere measurement? Thanks in Advance.

  • How to change Find_Noms Preference for SCANS

    I'm performing a Find_Noms Scan and while executing it, I got the good ol' error asking me to adjust my tolerance. I mistakenly told it to delete the hits that didnt meet the tolerance: How can I undo this? now whenever I run the feature it will delete…

  • calibration issue ?

    Hello all! I just really confused my self here. I heard someone last week saying the my CMM calibration ( Global Image) calibrates in Microns.? I always though it was on the tents. I'm inspecting parts that are .0004 tents on profile, I get results…

  • Help with profile

    Guru's - what would be the best method to check this profile? I could tell you what I did - but it's probably incorrect since I'm here asking for help. Also, do not have scan capability. Attached Files

  • Scanning Report

    I'm trying to create a scanning report that one of our engineers is looking for. I'm attaching a picture but what they want to see is an outline of the low tolerance of a profile, an outline of the max outline of a profile and an outline of where the…

  • understanding unequal tolerance reporting

    I have a profile with only a negative tolerance. How is my measured value positive, but the part is checking outtol=0. is the meas on the report an absolute value? I am exporting everything to measurlink and it is having trouble with the negative tolerance…

  • best analog scan

    I am struggling with this particular feature and i am not entirely sure why. I had it scanned 3 times by linear open scans then combined them in a constructed feature set. I dimensioned that as a profile of a surface, but it was not working properly as…

  • legacy profile

    Is anyone here familiar enough with legacy profile to explain the difference between form only and form and location? I think that form and location locks to the origin, but i am not sure how the form only works. I have a customer who wants to use legacy…

  • Xactmeasure questions concerning Profile.

    I have been tasked with explaining some items concerning a program I inherited concerning Xactmeasure Profile. I have a two part question. Attached is a pic of the profile dimension results and the D datum results. First, the call out is |Profile|0.010…

  • Saturday morning GD&T --- Surface profile of a diameter (cast cylinder)

    Morning all, Saturday morning, New customer, and PPAP being setup to run for next week, and one GD & T callout that leaves me scratching my head! The attached drawing shows the 40.8 Ø (+ draft (3° per notes is draft)) on a cast OD with a profile…

  • Scan results different from keyed-in points

    I have a part with a very tight profile tolerance (form+location) of .0005. I wrote a program with a model and aligned to all 3 datums. I keyed in gage points and read the vectors from the model. Part is out of tolerance (which I expected) by about…

  • Help inspecting profiles with screwy datum

    I have been given a part to inspect with the model. It has a surface profile w/in .0005, but I don't see how these datums really make sense. At first read I thought that -A- was the center hole, which would make -C- redundant. The engineer told me…

  • Im a Demis Newbie, Im really good at C@!^pso, what should i know......

    Ok so I followed a former boss to a new shop, he needed a programmer, but the problem is that this new shop has a whole host of B&S PC Demis CMM's, and I have all my years of experience in Zeiss Calypso. As far as I’m concerned the difference couldn…

  • Dwell before each hit taken?

    I noticed that sometimes when taking points along the contour of a part, I can see the readout showing good vector numbers while I scan, but after I make a point group and then try to make a profile dimension for the report, shows the numbers all over…

  • Government and Boss wants answers

    Haven't posted since I have become a member, mainly because I always seem to find my answer on older post. All except this one. My cmm wont give me a correct measurement. Its a poor musician who blames his instrument, I know, but follow me here. When…

  • "primary point does not lie on secondary axis, tertiary not allowed"

    Having a small hurdle to overcome here, would greatly appreciate a little advice if you got the time. Profile of a Surface execution scenerio...(dmis cad, not ++) Primary -A- = Zplus plane (leveled and z origin) Secondary -B- = Line on Yminus…

  • PC-DMIS 2010 MR2 - GD&T dimensions Dialog Box

    Recently I am installed 2010 MR2 version and I have a problem, more or less, with all GD&T dimensions, (Position, Circularity, Flatness . . et.). Actualy when I click on any icons,( or insert-dimension), only Xact Measure GD&T dialog box appears. I can…

  • Profile of a Surface

    Having problems tolerancing profile of a surface Using 2009 MR1 Tolerancing with Xactmeasure See attachment to see callout (dim 5) I measure two cylinders (one for each Radius R10 & R15) I get a couple of problems during tolerancing…

  • Dimensioning Profile from points

    When dimensioning profile of a surface, does pc-dmis recognize individual points or do you have to create a feature set from the points? VS 4.3
