Measuring Chamfers

I am using powerInspect for my infinite romer arm.

I am having a hard time figuring out the best way to measure a chamfer.

My exampler today was measuring the chamfer on a hole for a bolt on a wheel/tire assembly.

I was ablt to get some sort of .20 x 60 degrees measurements using calipers and a protractor, but i am hoping there is a way using PowerInspect.

I am new to this field and any help would be greatly appriciated.

  • i tried setting up a cone i tried it with 2 different probes. i measured it by hand at about 60 degrees and power inspect told me it was around 42...am i just not thinking about the angle correctly or is the range of accurancy much much higher as previously stated.

    I think the issue is entirely in your equipment. They 'claim' those arms are good to within tenths, but most people that use them (that I have spoken to and read on these sites) will tell you that a tape measure can be as accurate. Don't expect anything better than 0.005" accuracy out of an arm (so I have heard) and at that big of error, you could easily see 20-30 degrees difference from the actual of a cone that size.
