Using external alignment to run multiple parts instead of looping.

steelweaver120
I'm really close to ditching any attempt to use looping in my program to try and run multiple parts on my CMM table (I would like to run maybe 6 max). I'm trying to use 1 probe to inspect all the parts features (measuring on part, then going down in -Y 11.5" and doing the same measurement, go down in -Y again etc), then change probes, and measure all parts the same way (measuring all necessary features of one part, and then going down 11.5 inches in Y). The alignment keeps changing on me from the first part to the second...and when I post the data, 1 part will have the alignment from the second part. So, everything will dimensionally be okay, but because the origin is shifted down in Y by 11.5 inches, everything is screwed up on the total positioning (even though I know these parts will pass). How can I save one alignment/ do an external alignment, and then just shift it down 11.5 inches? I am sick of using looping, I feel like looping is really only for like bolt hole patterns, and waffle grid patterns in holes. Measuring whole parts in different locations is giving me a nightmare. It's something about the tool change and multiple parts. Because the second part doesn't get it's own alignment (like if your DCC alignment was A3, the second part should get A3-2 or something like that, but no. It just drives off the first parts alignment. I need multiple alignments just like the first part, just in different locations. I'll post the code just for giggles.

(TRIMMED SOME CODE AT END)
  • I've seen your threads pop up but haven't really had time to chip in yet.

    Can I ask why exactly you want to do away with the probe change mid program?

    Unless the cycle time is really critical your just adding (imho) unnecessary complexity.


    That said, if you go want to do it, the best option would be to use either a while/end while our a do/until loop, using external alignments to recall the correct starting positions, however, as you'll be looping twice (once with the first probe and once with the second, you're also going to have to save any alignments you generate within the first loop to recall in the second loop.

    These will have to have a unique name i.e ALN_ABC_1, and ALN_ABC_2, you would do this by creating a counter for each loop..

    ASSIGN/V1=1

    then
    ASSIGN/ALN_NAME="ALN_ABC"+V1

    then save the alignment with ALN_NAME.

    You would then have to recall those using the same method within the second loop.

    I think the main problem for me is 1.) I need to learn really fast (super small aerospace company with not many employees/management unwilling to spend lots of money, so I have to figure things out on my own time/learn on my own). 2.) I come from a background more on the side of Basic programming and stuff like that. I *think* that I am describing the wrong thing/ looping won't work for me. The reason is that because it is shifting the alignments/I need more precision than what looping is doing. I am holding Total Positioning tolerances of .010 TP and using a fixturing plate on my CMM without ground pins. With the ground pins this should all be working/way more close. My theory (well, not really theory, because I can see that the alignment is shifting on the second/third/whatever number part) is that using looping doesn't adjust the alignment at all on the parts. It just drives off of the first parts alignment, and then I am shifting the loop by -11.5" in Y. It does a DCC on the second part, sure. But then the first parts data is being driven off the 2nd parts alignment coordinates. The Y's are perfect, they aren't messing up because I told the computer to go exactly -11.5 inches in Y...BUT the X's are shifting/I'm getting really screwy TP because the X's aren't going back in the same place every time. I don't have ground pins, I'm just using a washer bottomed hex head screw (it's got a round bit near the table, but can be screwed in with a socket wrench). These bolts aren't good enough for the looping pattern, and the looping just doesn't account for the 1st and 2nd parts actual positions. If it created an Alignment 1 for part 1, and an alignment 1.2 for part 2 for example, it would work. But each part is sharing an alignment. That's why I'm asking if anybody has used Variables/if and if end statements, and just shifting the alignment down -11.5 in Y because that would be much easier I think. I *could* just write it out....like copy and paste my DCC alignments, and then create a new alignment for each part on the table and shift it, but that is going to take a lot of tweaking and a much longer program. I wanted to get back into the swing of using logic statements. I am really sorry, I've probably confused the heck out of everyone on this forum. I'm going to go back and answer each persons comment, I am so sorry for being rude, but I am just desperate to learn as much as I can as fast as I can.

    I'm at the point where I don't even want to read another one of your novel-posts man. Please try to be more succinct.
    Loops work great, but they are generally intended to loop based on each physical offset, not with the added complexity of one probe at a time.
    Why add all the extra drama and split the routine by probe? Do you not have a probe rack?
  • i just use copy/pattern for multiple of the same part. works like a charm.
  • in reply to NinjaBadger
    There's a lot of things going on here. I sense your frustration. Sorry I can't be of more help, I'm really not a looping expert. I do wanna mention a couple things though
    .
    1- You have an awful lot of alignments. Maybe it's necessary, I dunno but typically an alignment recalls the previous alignment. For example, you're doing a manual alignment to locate the part but your 1st DCC alignment is recalling machine startup, not the manual alignment. Your 2nd dcc alignment is also recalling machine startup, not the 1st dcc alignment. This may be some of your problem. But I feel the reason your TP callouts are out of spec is because your second loop is not related to your alignments in your 1st loop. This is why I suggested earlier running the entire program, tip change and all, first and the allow the loop command to take you to the second part and then run it completely.

    2- you said earlier that the original one-off program works fine. OK, use that one. I really don't understand where you benefit from a loop if you're having to manually change probes. In my mind it's just as easy to swap parts and hit go as it is to manually change probes in the middle of a loop.
  • in reply to BIGWIG7
    Can you be just a little more descriptive? Are you implying do an alignment on one part, and copy and paste all of the alignment and movepoints and everything into another alignment? And just repeating that process for as many parts as I want? How do I change the offsets of where the additional parts will be?
  • in reply to NinjaBadger
    haha man, I'm sorry about that. I talk x10 more than I write out, so there is at least that to be thankful for. Okay, what you are describing is *probably* why loops are not going to work for me- I was trying to loop the parts with one probe, do a tool change, then inspect the parts again starting on the first part alignment. But loops aren't cutting it because I'm not using ground pins (I think). I'm pretty sure loops are better suited for things like bolt holes/ patterns in ONE part, not using it to make a pattern for multiple parts. It probably would work with just one probe and ground pins, but the way I'm using it for is no bueno. And no, management is hesitant to buy a probe rack. Also I only have 2 probe modules, so I have to deal with that as well (tear down and build up a lot). I've been using PC-DMIS fairly regularly for a year now, but management will not pay for me to go to a formal class, and all the local resources/QC guys don't know as much as y'all. In fact, the guy that helped me the most getting off the ground told me that running more than one part was impossible/ stupid to do for QC. I didn't take that very well so just decided to figure it out on my own. Life sucks lol.
  • in reply to NinjaBadger
    Okay, even though I'm making myself look foolish, I'm getting somewhere posting my code for y'all. To answer your questions in order as best I can: 1.) I was not taught ANYTHING, even by Hexagon when I went to their basic CMM 101 class (which was pretty much overpriced b.s. lol a week to teach a simple manual alignment and DCC...what a pyramid scheme) about recalling alignments. It's something I should be doing for each new alignment? Recalling the previous and building on it? Why doesn't PC-Dmis do that by default? Nobody really described the theory to me, they just started clicking and showing me. Most of the time when I ask a question in person the answer is "because I was taught that way". I am literally a chimp with a machine gun flying an F-35.

    2.) Yes, the program that I wrote where it is running one part at a time works marvelously, the TP and Diameters of every hole and feature line up. My Micro-Hite agrees with that too. The reason I want to loop/do more parts at once is simple volume. I'm one QC guy with 4 machinists basically. There are times when I need to batch inspect aka slap 6 parts up on my fixturing plate on the cmm, clamp them down in a sensible pattern/grid. Hit go, and walk away to go do other things. I don't "stay in the lab" like most QC guys because we are so small. I might have to hit start on my CMM and go run a lathe or deburr parts for inspection. To make it even more complicated, our management isn't very good so I might have a situation (very common in the past) where I will have a stack of parts that nobody knows if they are good or bad because either a.) they weren't checking them properly or b.) they were looking at the wrong print and didn't use the right measurements to inspect it out by the machine. As far as hitting our ISO 9100D goals (actually inspecting them for TP /requirements all that), it's getting done, but the volume is drowning me. It doesn't help that management expects a new program to just be written in 30 minutes/ able to be adapted quickly from one part to two, or just want me to push go on the cmm and go do something else. As far as you saying why the tool change in the loop, it was just for saving time. Inspecting part 1 with probe 1, doing a tool change, then inspecting with probe 2, then having to change for probe 1 again for part 2, then probe 2 for part 2 just adds so much time. Also the calibration because we don't have a probe rack lol.

    It's a nightmare I know, I'm sorry.

    THANK YOU!!! I am going to have to read up a whole lot on this. This was never taught or even mentioned to me at the Hexagon lab I went to or other QC people I've met.
