I have a task where I need to measure a diameter on a thin part made of rubber (like a rubber band or O-ring).
But when the part is made of rubber and deformed (not round) will calculation of the diameter not be possible by using the normal circle calculation program in PC-DMIS. But I need a method to calculate the circumference/length of the surface/contour on the diameter.
The diameter will be measured with optical scan at a Mycrona CMM.
What opportunities are there in PC-DMIS CAD + + (version 4.2) to calculating the circumference / length of the contour of a curve.
Do you have access to a mandrel? If so, and you do not need to know the inside Ø of the o-ring, you can place it on a mandrel to measure the outside. Be very careful so you do not cause it to stretch.
