NettetIn order that fit function could be satisfied, it was found sufficient to manufacture a given workpiece so that its size lay within two permissible limits, i.e. a tolerance, this being the variation in size acceptable in manufacture while ensuring the functional fit … Nettetfundamental tolerance. A tolerance assigned to a fundamental tolerance grade, e.g. IT7 and a nominal dimension range , e.g. to 50 mm. fit. Planned joining condition between hole and shaft. ISO system of limits and fits. fundamental tolerances. nominal dimension in mm. micrometer (1/1000 mm)
