A tolerance is the total permissible variation of size. where the tolerance is the difference between the limits of size.
Range of tolerance grades that various machine processes may produce under normal conditions:
| Tolerance Grades | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
