Optimal Tool Selection for Environmental-Friendly Turning Operation of Aluminium

Abstract

In case of machining of automotive parts in large series it is necessary to change to machining operations, sparing the environment. The paper summarises the experiences of the authors, gathered in turning operation. With the help of experiments, planned, carried out and documented systematically, determine the conditions, considered to be the most favourable for the fine turning operations of high silicon-content aluminium cast parts in order to achieve the most advantageous surface roughness parameters. They deal with the topographic examination of surfaces, describing the working characteristics of the machined parts; furthermore, the topological maps of the surfaces, machined with diamond, will be introduced as well. The most favourable parameters were determined not only in the case of tool material and optimal edge construction in case of selection of cutting conditions.
