Abstract

This paper describes a method for analysis of tolerances in micro manufacturing. It proposes a mapping oftolerances to dimensions and compares this with current available international standards. The analysisdocuments that tolerances are not scaled down as the absolute dimension. In practice a tolerance level of 10 -100 μm seems to be the preferred level no matter the absolute dimension.
