 · Tolerance is simply a measure of acceptable variation (or deviation) in the dimension of your part. Simply put, machining tolerance allows you to specify a part's maximum and minimum dimensional limit. It is typically expressed using "±" (pronounced plus or minus) and accompanied by an acceptable deviation (for example, ±0.05).

The measure of the total space irregularities on the surface metal is known as Surface Roughness. It also depicts the number of peaks and valleys on a surface. The lower the number, the lower the irregularities, implying low surface roughness and a better surface finish. When professionals refer to surface finish, it is often 'surface ...

 · Because of its manual nature, rail cutting requires a larger leeway in the form of a larger machine tolerance. For this reason, AMI typically uses a machining tolerance of ±0.031″ for this machining method. If you are unsure as to the best machining method for …

At Protolabs, our standard prototype and production machining tolerance is +/- 0.005 in. (0.13mm). But if you need greater accuracy, there's our standard precision or production machining tolerance of +/-0.002 in. (0.051 mm). ... The most stringent tolerances may require secondary machining steps like grinding, polishing or Electro Discharge ...
