Program Accuracy

dhoughton
I've been programming CMMs for about 8 years now programming in PC-DMIS for almost 2 years. I've been interviewing for a programming position's lately because I'm moving and I keep getting asked how do I know the program data is correct or accurate. I haven't really been asked this before and I've been saying that I check the data of my features used for alignment and calibration results but I'm not sure if this is the right way of checking.

Does anyone know if this is correct or if there is a better way to check the accuracy of the data generated from a program?

Thanks

  • They want to know that you can back up your CMM inspection with traditional inspection methods.

    If you write a program, you or SOMEONE should be able to prove out each and every dimension repeatably via plate layout or other means.

    Believe it or not...I've ran into some programmers that can't even use a pair of calipers
