Total runout is more stringent than cylindicity. Using total indicator movement / total runout would suffice, but depending on the geometry of your part, you could possibly reject good parts. The surface must fall within the extents of that tolerance zone. may be right and you're not understanding, or he may be wrong.Ĭylindricity is a bilateral, parallel tolerance zone around the feature of size you are measuring.
That's your responsibility by agreeing to a contract to supply parts with certain expectations.Ģ) Your M.E. 1) It's not the responsibility of the customer to provide you with the means to measure/verify dimensions.
