Focusing on the characteristic of hard-to-grinding for titanium alloy,systemic process experiments was done about grinding TC4 titanium alloy under the high efficiency deep grinding condition.Based on the analysis to the changing and characteristic of unit area grinding force F' with maximum undeformed chip thickness hmax and equivlent cutting thickness aeq,this paper discussed the changing of its material removal mode and analyzed the changing and characteristic of grinding force ratio N、specific grinding ...
