Experimental determination of chip compression ratio during counterboring

Abstract

Chip compression ratio is used for the analysis of deformations that occur in the process of machining during chip formation. The value of this ratio is influenced by many parameters of cutting process. Based on experimental results, the paper presents a mathematical equation of chip compression ratio dependence on cutting speed, feeds and counterbore diameter. 3D diagrams have been obtained using MATLAB software system, on the basis of the above-mentioned mathematical equation. These diagrams show the effect of s(mm/o) and v(m/min) on chip compression ratio for three different counterbore diameters used in the research.
