Experimental Studies on Forces and Specific Energy in High Speed Grinding of Titanium Alloy Ti6Al4V
High speed grinding technology has great help about high speed grinding in application to the grinding of titanium alloy.In order to search the efficiency way to grinding the difficult to grinding material,the high speed grinding tests of titanium alloy Ti6Al4V were systematically conducted by using three wheels:brazed CBN wheel,ceramic bond CBN wheel and electroplated CBN wheel.Different equations of the maximum undeformed chip thickness agmax are adopted for different wheels based on their topography.The experiment results revealed that the grinding forces are increasing following the increasing of agmax,and the forces decrease slightly while the grinding speed vs rise,the specific energy decrease with an increase in undeformed chip thickness firstly then reduce slightly.Particllarly,the removal rate is highest for brazed CBN wheel when the same specific energy is consumed.These phenomena indicate that with adopting the reasonable agmax,high speed grinding with brazed CBN grinding wheel can improve the grinding efficiency and reduce the energy.
