[Cl...] Posted June 29, 2021 Share Posted June 29, 2021 Trying to pass a type1, but keep getting high percentages (50+%) for runout. The callout is .001 runout of Datum -A- to Datum -B-. -A- is a .220 x .528 Ø cylinder and -B- is a .800 x .3730 Ø cylinder. Tried various strategies, i.e. cylinder to cylinder, circle to circle, circle to cylinder. Nothing seems to work?

[Ad...] Posted June 29, 2021 Share Posted June 29, 2021 Usually when I have issues with runout or concentricity, I check the circularity of the cylinders and use roundness to determine if the diameters are round or oval shape. This way you might have an idea that the part is running out of tolerance because the cylinders may not be "perfectly" round. Or try using points instead of scan to see if you get a difference in readings. But I am sure there are other methods.

[Ow...] Posted June 29, 2021 Share Posted June 29, 2021 Circle to circle is dependent on the spatial and planar alignments. Cylinder to Cylinder, be sure to use at least 3 circle paths in each cylinder, equally spaced in the full length of the cylinder.

I think those two things present problems. Link to comment https://qualityforum.zeiss.com/topic/12608-runout/#findComment-63160 Share on other sites More sharing options...
