However never having worked with plastics and draft angles I'm not 100% sure, but if the surface is at a slight angle and it's meant to be (i.e. As for what you should do I'm with Jeffman, you should probably leave it. Oh, and I never change the vector of "CAD IS MASTER" cad data.

I've read about others who have to do the same as you, but I don't know why. Pcdmis has always selected the vector to match the side of the surface I click on, no matter what the alignment or probe orientation is in relationship to the surface. I've never EVER had to flip vectors when using the 'inside' of stock to check the fixture (or in your case, the mold). Since I want (need) clean wireframe images of the part, I put 'outside' (check side) of stock on one layer, 'inside' (fixture side) of stock on the other layer (with the edges). I generally get both sides of stock for the part in the CAD data. Working with moulds though there may be an instance where you HAVE to alter the vectors, if you have CAD of the mould but the part needs measuring or vice versa then you would need to flip every vector (otherwise it tries to probe from the opposite side (This happened to me in front of a customer and made their visit slightly awkward )I still program using V3.7. If not then at least you have a scapegoat. I find its easier to leave the vectors and pray that the CAD engineers have done their job right. Personally I never change the IJK values, I work solely with composites so a lot of the time (as said above) the IJK looking weird is because of a draft angle. When you do an aligning function such as Level or Rotate, you're mapping the specified axis to that vector.

So a vector of 1,0,0, means the direction (that can be of a line, the surface normal of a plane, a cylinder of cone axis) points completely in the x plus direction.Ī vector of 0,1,0 points completely in the y plus direction. We use ijk instead of xyz so as not to get confused, but I think of them in terms of xyz, Probably more important with working with PC-Dmis is understanding vectors and alignments.Ī vector describes a direction (relative to the coordinate system) draft) then if you do square it up, then you will get cosine error. Since you're working in plastics, I assume that you're working with molds? If so your I J K numbers are representing the draft angle on your parts.This is most likely it. Hope my questions make sense and i hope to hear from you all soon so i can start gaining some confidence in my programming! With that said can someone explain to me what vectors and IJK values are for in pc dmis and how they can afect a program if they are incorrect, or even how they affect programs when they are correct. I'm not brand new to CMM programming, im just brand new to pc dmis, i have prior experience with Calypso, i do not recall dealing with IJK values or vectors when programming with Calypso. Now, since i am programming off of CAD do i leave the IJK values alone? Or do i need to change them to I=0, J=-1, K=0? Do you ever change the IJK values? What about when programming when there is no CAD model? Do you ever change the IJK values then? When i went into the F9 edit window of this plane i noticed the IJK values were something like I=0, J=-.9998, K=.0023 (bare with me, i cant remember the EXACT numbers). I was working on a program for a part today and picked points on the CAD model to measure a plane.

Now, a couple things im having a hard time wrapping my head around is vectors and IJK values when programming from CAD. I want to be diligent and make sure my programs are representing my parts as close as possible (i work in the plastics industry and that is what i will be measuring).

I'm brand new to pc dmis as of a couple weeks ago (took the pc dmis 101 class).
