As we know accuracy does not exist anywhere, the only thing we can do is to try to approach the true value as close as possible. So, to provide a little flexibility to a manufacturer the designer makes use of tolerances and fits, which in turn determine the kind of assembly produced. Explanation: Every production process involves a combination of 3 elements, i.e. man, material, and machine. It is not possible to make any part precisely to a given dimension. Even if by chance the part is made exact it is possible to measure it accurately enough to prove it. If attempts are made to achieve perfect size the cost of production will increase tremendously. Therefore, some permissible variation has to be allowed. Limits: The dimension of a manufactured part can only be made to lie between max and min limits. Tolerance: The permissible variation in size or dimension is tolerance. The difference between the upper limit and lower limit of a dimension represents the margin for variation and is called as tolerance zone. Also, it is the amount by which the amount is allowed to go away from accuracy without causing any functional trouble when assembled.
