Can someone please help me understand how PC-DMIS calculates angularity. I'm checking the angularity between two lines that are called out at 45 degrees and the angle is measuring 44.89 which is well within spec. The angularity callout is 6.3 but on the legacy angularity dimension it is giving me a measured value of 35.001. ????
I am thinking the angularity result will be directly affected by the length of the line being measured.
The angularity measurement of a 1.000" line deviating -0.11 degree is less than the result of 2.000" line deviating -0.11 degree.
Angularity of 6.3MM on a "short" line could be a very large angle change.....
I had to explain this to someone recently. They were not understanding a thing until I said its the same a perpendicularity but at any angle you need ? Perp is just angularity that happens to be applied to only a 90°.
I would check the workplane...
35 mm of angularity shouldn't result of a machining defect (except if the operator has drink too much !), I think it's a construction error...
