Influence of the tool edge geometry on specific cutting energy at high-speed cutting [PDF]
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2007 This paper presents specific cutting energy measurements as a function of the cutting speed and tool cutting edge geometry. The experimental work was carried out on a vertical CNC machining center with 7,500 rpm spindle rotation and 7.5 kW power. Hardened steels ASTM H13 (50 HRC) were machined at conventional cutting speed and high-speed cutting (HSC).
