Tolerances. Variation is Unavoidable. No two manufactured objects are identical in every way. Some degree of variation will exist.Engineers apply tolerances to part dimensions to reduce the amount of variation that occurs.. ANSI/ASME Standard. ANSI/ASME Standard Y14.5Each dimension shall have a tolerance, except those dimensions specifically identified as reference, maximum, minimum, or stock. The tolerance may be applied directly to the dimension or indicated by a general note located in the 34135

20. Three Types of Fit There are three types of fit that should be considered when working with tolerances. Clearance Fit- have limits of size so prescribed that a clearance always results when mating parts are assembled. Interference Fit- have limits of size so prescribed that an interference always results when mating parts are assembled. Transition Fit- have limits of size indicating that either a clearance or an interference may result when mating parts are assembled.
