Hi guys, I have a question regarding how PC-DMIS calculates angles. My part is gas turbine blade (3.7 MR1).

I have a report that dimensions angle in Deg,Min,Sec. I usually checking 4 angles on upper bearing flank, and 4 angles on lower bearing flank for 45 degrees. All looks OK just one of them don’t show same direction of deviation like others.

If I set on nominal exactly 45,00,00 degree, my results is 45,05,24 ,but on the other hand,

If I set on nominal just 44,59,59 degree, my results is 44,54,36. It is absolutely same deviation but on opposite direction. Could someone tell me where I am going wrong.

Thanks,

Lubo
