ANALYSIS OF PHYSICAL CAUSES OF MACHINED SURFACES IN SELECTED MACHINING METHODS

Abstract

In this paper, we will try to theoretically calculate, and experimentally determine the roughness of the machined surface in terms of the physical causes. The surface roughness has been experimentally obtained for two turning methods, which are challenging both in terms of setting the cutting conditions and in terms of the economics of the experiments performed. These are the deep turning of hardened steel internal holes and the internal turning of internally shaped surfaces. The article will point out the theoretical calculation of machined surfaces' roughness by the cutting theory and the experimental results obtained.
