Straightness
Straightness
(OP)
Is it posible to measure the straightness of a rod by chucking it in a lathe with an indicator in three different locations? I believe checking runout or total runout is not the same thing as straightness.
I check a rods straightness on a surface plate with feeler gages, on a CMM, or on an indiron.

RE: Straightness
Our receiving inspection bar "straightness" specification defines 2 support points and 3 measurement points with a few qualifying notes about "short kinks" etc. Can only be used down to a size that does not droop excessively.
I would not use it on a precision part.

Is this an axial straightness exemption from perfect form at MMC?
