Optimal machining parameters for achieving the desired surface roughness in fine turning of cold pre-formed steel workpieces

摘要

Cutting parameters, workpiece material and cutting tool geometry and material all have an essential influence on the achievement of desired product quality at acceptable cost. The machining of prior cold-formed workpieces is a common production route that is economically attractive. This paper deals with the issue of optimising the turning of raw workpieces of low-carbon steel with low cold pre-deformation to achieve acceptable surface roughness. An attempt was made to minimise the number of experimental runs and increase the reliability of experimental results. Conclusions include a description of the machining parameters' influence and levels that provide sufficient robustness of the machining process towards the achievement of the desired surface roughness.
