Abstract:

Focusing on the characteristics of hard-to-grinding for titanium alloy, systemic process experiments was done about grinding TC4 titanium alloy under the high efficiency deep grinding conditions. Based on the analysis to the variations and characteristics of unit area grinding force F′ with maximum undeformed chip thickness hmax and equivlent cutting thickness aeq ,this paper discussed the variations of its material removal mode and analyzed the variations and characteristics of grinding force ratio N,specific grinding energy es with corresponding parameters further. Then,it was analyzed about the consumption of grinding power on the process of high efficiency deep grinding for TC4 titanium alloy.

Key words: titanium alloy, high efficiency deep grinding, grinding force, specific grinding energy, characteristics
