True Positions & MMC Hole Datums

$

I would like to ask a question due to the fact that me & some of my coworkers are having a debate & cannot come to a definitive answer - I was hoping someone here might be able to settle this discussion.

First let me explain the situation - We are a metal stamping company & we make lots of small automotive parts. Most datums on our prints consist of: a plane for Datum-A, a hole for Datum-B & a hole for Datum-C. The item in debate pertains to true position call-outs of other (non-datum) holes. The true position is called-out on a hole (MMC) back to A-Datum/B-Datum (MMC)/C-Datum (MMC). Some people, including myself, claim that in this situation, it is not uncommon to have a 0.00 TP. I have explained that the MMC bonus on the hole being dimensioned is the only thing that provides additional TP tolerance. The MMC of the datum holes do not provide additional tolerance. PC-DMIS takes what would be the MMC "bonus" of the datum holes & subtracts that from the dimensioned hole's TP. Therefore, if your dimensioned hole is close to being on target & there is sufficient MMC "bonus" (or actually Datum Shift) from the size of the datum holes, then you can easily have true positions that equal 0.00.

Please everyone - reply back with your knowledge on this so that this discussion can finally be settled one way or the other.

Thank you all so much!

Feature id labels

I sometimes call in old programs from many moons ago into pcdmis 2018 r1. Why do the feature id labels on the cad, some show up, others are blank? No matter what I try, they do not appear, turn the cad, go into edit, feature appearance. I have noticed this on a few old programs, but not all. Any ideas from the masses? I would appreciate a possible fix, roadmaps do not look good with blank labels.

Hidden export option ?

Hello,

I have a strange issue on one of my program.

Everytime I execute it, it creates an excel export file.
Even if I underline a small part of the program and use 'execute block' it creates an export file.

I checked all the lines and there is Nothing related to excel export.

Removing Empty Value from Form Dropdown List

$
0
0
Hello!
Running PC-DMIS 2013MR1
-------------------------------------
I have a form that takes operator input at the beginning of every part program.
When I start the program, the initial value is empty; in order for one to be selected, I have to manually select one from the dropdown list.
While that works all well and good, I'd like a default value, so I can start the form and have things already filled out.
I run programs 97% of the time, so I really don't change it; hopefully it makes sense what I'm asking for.

I'd be happy to post images and code that I'm working with to help paint a better picture

Cloud of Points

I am trying to capture several different profile callouts via a part scan. I figure since there are several different sections with different call outs, I must need a COP for all features. My problem is this, I have programmed the COPs accordingly but, when I try to run the program it wants to skip over everything after the first COP. What do I need to do in order to capture several different surface profile callouts?

Mini Routines

Good morning everyone,
What is the best way to setup Mini Routines without the use of variables? I don't want to have to write a shorter program, I just want to be able to run the critical features when I have to. If I have to use variables, can someone help me with that? Thank you ion advance.

Xactmeasure composite FCF won't release DOF

$

Hi all,
Here are a couple of callouts for reference. Would I be correct in saying that Xactmeasure won't properly evaluate the second half of the FCF per Y14.5, 2009 and that I need to evaluate them with legacy using a best fit? From my attempts at doing this in Xact it won't release the translational DOF for the second half of the FCF and show me the shift. It simply reports the exact same results as the first half with all degrees constrained and a tighter tolerance. If it can be done in Xact, how?

Thanks!

I am trying to report the groove depicted in the snippet perpendicular to datum D and with total runout. EM tells me this isn't possible because I didn't measure the groove as a cylinder. What is the best why to report this?

External Alignment Issue?

$
0
0
One of our supervisors broke a shank tip when taking a manual hit on our shop floor 454. He then tried to remove the Tesastar head to swap it with one from another machine. Then realized these are wired into the Z Axis after he took the cover off the column. He put it back together and let us know the tip was broke.

The old tip was replaced and re-qualified. This looks good.

We use fixtures to locate our parts the same on the surface plate each time. The programs are setup to recall an external alignment for the part, then measure the alignment features in auto. Then do an alignment on each part run. Since the tip incident, the auto hits for the alignment are off/shifted in both X & Y directions. I thought we may need to relearn the external alignment to correct this.

After relearning an external alignment, the program runs good, but errors after the same feature. The message we get is ERROR CE, 5%1, TR_CE, 0X1400204D Position out of the machine stroke limit on Y Axis. I have a loop within the program, and we also loop the program. I've learned when making changes to programs with loops, set the loops to one, then run the program. Then the Theo's are displayed correctly.

Setting the loops to one does not help. Still have the same error.

Not sure if the supervisor did something to the machine? The tip qualification ran and looked good. The programs have been good for several years now without issues.

I will look at the alignments leading up to this error to make sure they are correct.

Any suggestions?

Datum target

Good afternoon.
first time I have to deal with this in pcdmis. im gonna post a sketch of the part looking for some advices to align this part.
the sketch shows 3 datums target on A (A1,A2,A3). dand then datum b and datum C.
I just don't know how to use this datum target on pcdmis.
Any question please let me know.

thanks.

Please see the below code.

            OUTLIER_REMOVAL/OFF,3
            FILTER/OFF,WAVELENGTH=0
How can i pull all the points from the lin1 in the loop to create a plane?
In this example i have 23 lines to construct a plane.

I could use LIN1[1].hits[1..lin1.numhits] all the way through LIN1[23].hits[1..lin1.numhits] to construct a plane this time.
However another part may have 25 lines, or 12. So V7 won't be constant.

The do until command is just a counter for others to know where i get the count from.
The loop runs fine.

Just can't figure out how i can, or if i can, to pull all the hits on an unknown loop count.

Invalid reading of the measured point

$

Hi, when running a program in PC-DMIS it sometimes gives me the error: "Invalid reading of the measured point". Then I press play and it can continue, but sometimes it doesn't and gives me other errors like:

1) system error wrong status task
2) system error application board error
3) command cannot be executed beacuse the motors are off

The error comes up when the probe is in prehit distance, so it is not in touch with the product..

Anyone an idea?

Onerror

I am trying to use the ONERROR (edge not detected) command allow the CMM to locate a part fixtured on a mandrel. It is a part we have to measure with the zoom lens. I would like for it to first look at specific coordinates, then subtract .5mm each time it misses. I'm getting no where. I've done something similar before in Level 3 training, but that was several years ago. I'm on PCDMIS 2012 MR1 and an Optive Performance. Any ideas?

Thanks!

VB output to excel

I have a script that i found on here somewhere that creates excel reports and imports all the data in rows. I would like for the data to be imported in columns. I tried it by changing all the row commands to column and all column commands to row, but with no success. What am i doing wrong?

Also, what did the Let and Set assignment statements change to or what they have been replaced with?

Thanks

Getting a New CMM

$

Good Morning,

I have 3 4.5.4 SF using 2016 pc-dmis cad and tp20s. I need a quote for another CMM. I would like a Tigo instead of another 454. I proved a part with some long probe builds and I have concerns about its accuracy. 1 build is a medium force, 10mm ext, 5 way, and 4x40 in the y+ direction. It has to be this long to reach inside and check some critical features, rotates 180 degrees to y- and checks the other side.

Everything calibrates good but I still have concerns about its length. My part was sitting on the shelf and it was coated with a rust inhibitor so there is some build up on its surface. I cleaned the best I can and of course I get bad results. The inspection part will be bare metal.

My question is what probe build would a scanning fixed head on a Tigo have and so I can at least try and build it offline to see if the head will fit inside my part. Running 2016 so I don't have the updated head names and i can't scan anything either. Just want to see if it fits.

thanks.
