ABSTRACT
Turning of small parts is not new, but challenges arise when the size of features reduce to tens or hundreds of microns, and the precision requirements of the miniaturized parts become less than a few microns. Even though microturning is a miniaturized version of macro/mesoturning, there exist a few fundamental differences between them. Some of them are as follows:
r The main feature that distinguishes macro/mesoturning from microturning is the size attribute of the component, specically the diameter being machined. Macro/ mesoturning is applicable to component diameters of ≥ 1 mm, whereas microturning is applicable when the diameter of the component is < 1 mm. Although there are different denitions for the upper limit of the diameter in the case of microturning, machining of < 1 mm diameter is generally accepted by many.
