Guide to CNC Machining Tolerances Fractory

2020-11-10  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 difference between two parts that perform the same function may not even matter.
