MATHEMATICAL MODEL OF CUTTING FORCES WHEN WIDENING HOLES IN STAINLESS STEEL X15CrNiSi20-12

摘要

The paper presents a series of experimental data concerning the widening of the stainless steel X15CrNiSi20-12 and the ways and means to determine the cutting forces with respect to the specific working conditions. It represents the contribution of the authors to the estimation of the polytrophic exponents and to the assessment in terms of structure of the cutting forces equation. Afterwards, the paper presents the graphs for the variation of the cutting force components with the parameters of the cutting technology. The obtained results can be implemented in further research, in order to increase the productivity of steel machining.
