Answer
Tolerance is significant in manufacturing as it facilitates the interchangeability of parts. If a part is produced within its specified tolerance limits, it can be replaced with minimal risk of assembly failure. It directly impacts quality control and production efficiency.

Answer
For instance, if the nominal size of a component is 20.00 mm with a tolerance of 0.15 mm, the upper limit will be 20.15 mm and the lower limit will be 19.85 mm. This means that any measurement falling within this range is acceptable and meets the required standards.
