How to Interpret Geometric Tolerance and Dimensional Tolerance
Hi,
I'm confused with the Geometric Tolerance and Dimensional Tolerance. I have read many articles but it had not solved my doubt. I'm confused on how to put tolerance on a shaft and hole with Geometric Tolerance and Surface finish of 0.2 micrometer.
This is My Issue:
I have to design sliding fit of 15.988+/-0.005 (Shaft) and 16.006 +/-0.007 (Hole) dimesional tolerence that gives a clearance of 0.0298 and allowance of 0.006. Which provide me a Sliding fit.
When i add geometric tolerance to this with cylindrical(0.002), circularity(0.002) and parallelism(0.0025)
with
Surface Finish of 0.2 micrometer
MMC of shaft will be -> 15.993(MMC)+cylindrical(0.002)/circularity(0.002)+parallelism(0.0025)+Surface Finish(0.0002)= 15.9977mm
OR
MMC of shaft will be -> 15.993(MMC)+cylindrical(0.001)/circularity(0.001)+parallelism(0.00125)+Surface Finish(0.0001)= 15.99535mm
OR
MMC of shaft will be -> 15.993(MMC)
Similerly for LMC.
I'm confused on how to calculate whole.
Please help me with this doubt.
