After studying the material in this module, student should be able to : Ø Ø Ø Ø Ø Read and create limit dimensions. Describe the nominal size, tolerance, limits and allowance of two mating parts. Identify a clearance fit, interference fit and transition fit. Describe the basic hole and basic shaft system. Dimension two mating parts using limit dimensions, unilateral tolerances, and bilateral tolerances. Ø Describe the classes of fit and give example of each.

In manufacturing it is impossible to produce components to an exact size, even though they may be classified as identical. Even in the most precise methods of production it would be extremely difficult and costly to reproduce a diameter time after time so that it is always within 0.01 mm of a given basic size. However, industry does demand that parts should be...
