[Al...] Posted July 26, 2021 Share Posted July 26, 2021 Hello, I'm relatively new to Calypso (using it since end of last year) and now I want to know how to properly set up additional work coordinate system or Base alignment? I'm having trouble measuring some parts because I can't approach to all of the features in a single clamping operation, so I would like to add a new Base alignment system in the middle of measurement, so after all features from clamping operation no1 are measured, I want to add a program stop and then I would manually unclamp and reclamp my part in a vice jaws and I'd like to continue as if it was a new part in the vice (first clocking the Base alignment with a new clearance plane then measuring additional features in second clamping operation)... How do you do that? Thanks in advance, Alen Link to comment Share on other sites More sharing options...

[Al...] Posted July 27, 2021 Author Share Posted July 27, 2021 Thank you, but I've tried it earlier, the problem is that my safety cube (clearances) don't match the new part position and my stylii are in danger of getting hit on the part, I've tried modifying clearance values, but still, can't do it without complicating with adding manual CMM positions before every probing point. Is there a way to create 2 base alignments and select one (using resources - load alignment) in the first part position and select the other for the 2nd part position, along with their unique clearance cubes? I've tried messing with that, but no luck yet. Also, what is Start alignment? Seen some videos on youtube and looked into help, but I can't understand what this is used for?

[Ro...] Posted July 28, 2021 Share Posted July 28, 2021 #1 Do you have PCM? that would make changing your clearance cube variables at different points of the program pretty easy #2 all cool kids use start alignments!!! Just kidding, but i put start alignments in all my new programs, and have added them to most of my old programs as well. If your fixturing is good, and you can reasonably set your part square each time, then start alignment is for you. In my case a start alignment is just a truncated manual alignment, consisting of only 3 points, X, Y, &Z. It started with me with some really weird looking spinal implants we were launching for a customer, they had almost no flat or square faces, and all the datums were constructed planes. manual alignments would take 5 to 7 minutes depending on operator, and since the datum surfaces were covered in fins & ridges, bad manual alignments were common. So i saw something that made me try a start alignment that consisted of 1 point in X, Y, &Z, and we never looked back after that. Operators were giving me high 5's every day when i came in. I just told them, zoom in on the cad model, and take 1 point where the yellow arrow shows, ill make all the programs the same.FGESFGDFGFGE.JPGSFGDSFGDSFDSFDA.JPGxvfdfdfdsfdsfdfds.JPGjhhfghdfgdsfgd.JPG Link to comment Share on other sites More sharing options...

[Al...] Posted July 28, 2021 Author Share Posted July 28, 2021 Please sign in to view this quote. I'm working with autorun. It's measuring parts in series. Same part, same fixture, just reset and play start... Link to comment Share on other sites More sharing options...

No, in my part, base alignment is based on part inside fixture, but fixture can be moved, part is positioned in the same manner inside fixture every time...

[Al...] Posted July 28, 2021 Author Share Posted July 28, 2021 If it is impossible to have two base alignments in one program, what is the use of save alignment and load alignment under resources? Also, in the help, it was mentioned that you can have second program with different base alignment than the first program and you can call it from the same program. Is that the function of load alignment? I havent tried it yet, because it seems stupid to me that you cant continue measuring from same program with different base alignment, but if I dont find a reasonable way to do so, I will also try creating second measuring program for the same part with only base alignment for second clamping operation in a vice and try loading it from the first program. If you program cnc machine in a software like solidcam, catia, fusion, etc, normally, you can add additional work offsets to the same part program so you continue machining part until it is finished. Why wouldnt this be possible for measuring too? Link to comment Share on other sites More sharing options...
[Jo...] Posted July 28, 2021 Share Posted July 28, 2021 Please sign in to view this quote. I'm not clear on exactly what you are trying to do. I have loaded 2 models into one program. The first one is measured, establishes base alignment, and clearance cube relative to BASE alignment. The second model I position and rotate, then I measure features to establish a secondary alignment. This all works fine as long as the clearance cube covers BOTH positions. Unless you can work out the clearance cube issue, there is another option. Make two programs. One for first position, and another for second position. Then use autorun to run both, each have a base alignment and clearance cube. Someone will have to walk you thru this process, I haven't done this in awhile.

[Ro...] Posted July 28, 2021 Share Posted July 28, 2021 Make sure you are putting it into the presettings of your program, not a feature. With no features or characteristics highlighted, click on the peach P button After you type your variables in, you need to "Calculate" them, which will put the value into the variable. Highlight the entire line and click on the Magnifier & lightning bolt. Then later on in the program, maybe in the first feature of your 2nd alignment (you deff need to be running from features in this program), in the presettings of that feature put the new values for X,Y,ZPLUS & MINUS Additionally, you cant just put XPLUS into the box, you need to right click and hit "Formula" then put XPLUS in as your formula, then then you hit ok it will show up in the box.fdjhksfdjhksfdjhsfdj.JPGefdfdssfdsfdsfd.JPG Link to comment Share on other sites More sharing options...
[Ma...] Posted July 28, 2021 Share Posted July 28, 2021 There is always the option to program clearance positions and run the program without using clearance planes at all. Or you can use the existing clearance planes in the first part of the program and program in clearance moves for the second part. Link to comment Share on other sites More sharing options...
