The tolerance limit defines the maximum allowable difference between corresponding dimensions of the two parts. For CNC machining, the standard tolerance limit is set around +/-.005" (0.127 mm). For reference, the thickness of a human hair is 0.002" (0.05 mm). The standard tolerance limit is a small number and in most cases, such a small ...

The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [4] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.

Machining is often selected when tolerances are close, as it is more accurate than most other shape-making processes. Tighter tolerances usually mean higher costs. For example, if the product designer specifies a tolerance of ±0.10 mm on a hole diameter of 6.0 mm, this tolerance could be achieved by a drilling operation.
