Good Morning! I'm new to using CAD models. I only used them in class. I created a manual plane, line, point alignment to make the model aligned with the machine. The problem I'm having is when I change my alignment or workplane, my points are no longer aligned with my model. They are offset and mess up my dimensions. Do I need to continually redo the manual alignment to keep everything where it should be or am I missing something else? Thanks in advance!
DAN_M I know this is probably a dumb question, but I tend to not use CAD very often in programming. Why exactly do you have to line your cad axes up to your machine axes before you start programming? I'm going to tell the CMM which way is what when I do a part aliment anyway, so the original coordinate system will be overwritten. The axis labels are entirely at the programmers discretion.
Not a dumb question at all! Allowing a physical part alignment to square it for you works very well and is used by many people, nothing wrong with that at all.
The above being said...having the cad & machine square to one another in the beginning of the program is easier to work with (in my opinion). I can look at my code and see that all of the vectors make sense per how it is sitting should I ever need to troubleshoot anything in the future. I stuck with that method after learning both at Hex and have continued to teach others this way.
So this is where I'm at. I started a new program. I created a manual alignment using auto features to align my model with the machine. Then I used DCC and auto features for whatever I needed to measure. Everything lines up with the CAD and the dimensions are correct. The problem comes in when I change my tip from A0B0 to A52.5B90. I can select my auto features, but instead of being lined up correctly with the CAD, it shows my circle, plane, etc. offset from the actual location. When I execute my circle for example, it will crash since it is measuring offset rather than the correct location. Some people suggested using read points which I have used to execute my circle without crashing, but it’s still not aligned to the model. When I try to dimension these features as is, they are obviously wrong. When I try to do a new alignment after the tip change, the previously aligned features from before the tip change become offset and I’m unable to get the correct location and/or angle of my trihedron. Something about this is going over my head, I'm sure of it.
All the movepoints,readpoints. or clearplanes will not fix this issue. When your TRIHEDRON jumps around like that.....youre done... Im with post below. You tips are not calibrated in relation to each other. You using a master probe ?
If you are running online, do you see your probe in the graphic display window moving when you execute your program? I'm curious to know where the probe would be in the graphic display after you change head angles. I've never seen this problem before, so I'm curious to know whats going on as well.
After the manual alignment, the probe moves around the model as it should in the correct angle. It still looks correct after changing the angle, but is slightly offset in my Y axis.
I am using a master probe. I was swamped with something else today, but first thing tomorrow, I'll recalibrate everything and see how it goes from there.
