- Nominal size is the size of a part specified in the drawing as a matter of convenience.
- The actual size is the actually measured dimension of the part.
- Tolerance is the difference between the upper limit and the lower limit of a dimension.
- In other words, it is the maximum permissible variation in a dimension.
- The tolerance may be unilateral or bilateral.
- Interference: A negative difference between the diameter of the hole and the shaft is called interference.
Important Points
When all the tolerance is allowed on one side of the nominal size, e.g. \(10_{ - 0.004}^{ + 0.000}\;\) , then it is said to be a unilateral system of tolerance.
When tolerance is allowed on both sides of the nominal size e.g. \(10_{ - 0.004}^{ + 0.004},\) then it is said to be a bilateral system of tolerance.
