Plane With One Offset Point

bradacc
Good morning all. I'm actually a CNC mill programmer trying to learn our Romer arm with PC-DMIS 2016 with zero experience so hopefully someone can help me out. I did a search with no luck, so sorry if this has been asked before.
I have a part that I'm trying to do Quick Start > Create Alignment > Plane/Line/Point but I can't figure out how to have the orientation match the part. The problem is the plane has one of it's 3 points called out as -2.556" from the other two points, and the line has one of it's points called out as -.675".
If anyone can offer any help I'd appreciate it. And when I say I have zero experience I mean I just touched the program for the first time yesterday.....
  • Take points on the plane surfaces and then construct an offset plane to level to. The help files might help guide you Slight smile

  • I thought that's what I did, but my Z is coming out ~6" above the part, and it seems like my X and Y got hosed as well.
  • Your points seem to have a strange Z vector (actual)? You need solid points to build the plane. Origin on the plane in A1 and then report the Z values of the point to be sure they are now 0, 0, -2.556
  • So this came out close. The arrows are pointed the correct way, and my numbers seem to be the correct absolute value, but X numbers are showing negative instead of positive, and Y numbers are showing positive instead of negative. If I change "ALIGNMENT/ROTATE,XPLUS,TO,LIN1,ABOUT,ZPLUS" to "XNEGATIVE" the numbers come up correct, but the arrows are wrong.

    Either way I can't run past A1 without an out of range alarm being generated, even though the live update of the arms position looks correct.

  • Don't worry about anything until you get this plane thing beat, you need a plane to "draw" the line on. We wanna see a plane with a +1 Z vector and 3 points with the right Z value before we go any further.


    OK, I see you probed the 3 points again and the data is OK but the line has a minus Y vector not an X plus, that will mess you up.
  • Don't worry about anything until you get this plane thing beat, you need a plane to "draw" the line on. We wanna see a plane with a +1 Z vector and 3 points with the right Z value before we go any further.

    The last code I posted up gave me a good plane. Dragging the Romer arm around and touching each of my 3 points on the casting I was getting around Z+.1, Z+.1, Z-2.45.

    Thanks a ton for looking at this tking. I appreciate the help.
  • When you probe pnt 4 and 5 are they on the Y plus side of the part or on the Y minus, is 4 to your left and 5 to the right? The line has a Y minus vector and then you align your X plus to that so you're 90 degrees of to start and then the negative vectorrotates your alignment 180, hence the minus values you're seeing.
  • I brought in the model oriented exactly how the print is, so point 4 is on the lefthand side(back face) of the part at Y-.675, and point 5 is on the righthand side (back face) of the part at Y0. Point 6 is the righthand face of the part.
  • Points 4 and 5 have a theo vector as you describe but the actuals are way off. Before you probe them construct, level, and origin to the plane. Do they have a Y plus vector now? Does the line have a X plus vector?
  • Looks like it worked! Thanks a ton!! I'm not sure if I did it the way you were trying to explain to me, but I think so. I started with the same 3 points to create a plane, then used 2 of those points for a line so I could create an alignment. After that I did the real line/point to finish the alignment, then started all over with my 'real' 3/2/1 to create "A3". After that were a few point checks for sanity.
