Polar Points, Vectors and Variables

ELaFever2
Hey gurus,

I must measure impeller blades (9) and have been given a chart of X, Y, Z locations for points. The chart is only for the points on one blade. In my code below I have an example of how I am maintaining the nominals and expanding the points to the other blades.

What I am having a problem with is having the I, J, K vectors adjust along the same lines as X, Y, Z. Can anyone help me figure this out?
Or let me know of another way?

  • Well yeah The CAD models are Reference only. You need it to Reference the parts, and when your done writing the program take the Model out of the program, because it becomes pretty much useless after that anyway, actually your engineers are correct, but it shouldn't stop them from giving you the CAD. They use the CAD model which is the perfect part, so they can try to make the perfect part(can come close but there is no such thing) you take the CAD model and check parts based on the perfect part(which doesn't exist) Your CMM never actually sees the CAD model. It just does what you tell it to do. Lets say you have a hole at an angle and you choose auto circle, DMIS is smart enough to take the correct vector hits BASED ON THE PERFECT MODEL. Making programing a little easier.
