Abstract

tion of a new surface. The excess energy is consumed in elastic and plastic deformation of the blank and the tool and their mutual friction and creates elevated dynamic and thermal stress in the cutting zone. However, by varying the tool geometry and the machining conditions, the properties of the tool, the composition of the lubricant and coolant fluid, and other control parameters, we may create situations in which the same quantity of metal is removed with dif� ferent energy consumption and hence with different stress in the cutting zone. Correspondingly, the loads on the machine tool, the tool’s operating conditions, and the physicomechanical state of the part’s surface
