Abstract

Abstract

Based on considering the influence of cutting heat, the inertia effects of cutting energy absorption were studied by numerical simulation, and stable cutting force, cutting displacement, maximum temperature, heat dissipative energy and the dissipative proportion of thermal energy were computed under different initial impact conditions.Computation result shows when the initial impact energy is 20 kJ and there are no distinct initial cutting force peaks in chip formation, the stable cutting force ranges from 63.0 kN to 63.8 kN, and the changing rules and trends of cutting force curves are approximately same.When the impact mass is 200 kg and the impact velocity changes from 3 m·s^-1 to 10 m·s^-1, the stable cutting force ranges from 63.0 kN to 64.4 k N.When the impact velocity is 10 m·s^-1 and the impact mass changes from 0.4 t to 3.2 t, the heat dissipative energy increases from 4.12 kJ to 36.64 kJ, the maximum temperature changes between 586 ℃ and 602 ℃, the dissipative proportion of thermal energy ranges from 20.6% to 23.2%, and the stable force ranges from 63.0 kN to 64.1 kN. Obviously, when the cutting depth and the geometrical parameters of cutting tool are defined, the initial impact energy, impact mass and impact velocity have little effect on the cutting force, the inertia effects of cutting energy-absorbing process are insensitive, and the cutting energy-absorbing structure belongs to type Ⅰ.The cutting heat accounts for a large proportion of energy dissipation and is greatly influenced by the initial impact velocity.
