Greetings all,

I have a part that was hand drafted in the 1960's and in order to measure a chamfer they drop the part into a fixture with clearance below the part to accommodate a ball bearing placed into the chamfer finally they measure from the top of the ball bearing to the bottom of the part. This is the only dimension i have controlling this chamfer other than the degrees. For clarity the bottom of the ball bearing drops below the bottom surface of the part. If this were solidworks I could just mate a sphere to the inside surface of the chamfer and measure from there but I am uncertain how to replicate that functionality in PC-DMIS or if such behavior is even possible.

I also attempted to solve with linear algebra but there are at least 3 different variables that I would have to consider (part thickness, chamfer angle, & chamfer diameter) and that was more measurement error than I am comfortable with. Also given the age of this part I will not get a drawing update from my customer.

Any help or advice would be greatly appreciated Thank you very much for your time.
