The rod I am talking about is to check the alignment of 2 bearings 4 inches apart within .001in. The alignment rod feature numbers are already established.
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...
Dimensions are in mm. What would the tolerance be for the feature control frame "3.730 8x" dimension? The block tolerance on the print is +/- 0.125mm. I am told that the print block tolerance does not apply. I have never seen T.I.R in a feature control frame for flatness or parallelism with...
Thanks for your response. Yes I realize the feature form must be considered as stated at the end of my inquiry. The first bore is .4375 +.0005/-.0000 the second bore is .4365 +.0005/-.0000. The print call out is "two holes must be inline with in .005 TIR". The bores are both 1.000 long and...
I have an application where two seperated 1.000 x .475dia bored cylinders muct be within .005in TIR. The logical mechanical inspection technique would be to engage a snug fit gage pin into one of the cylinders and rotate the part on the gage pin with an indicator reading the other cylinder...
