Research on grinding force of titanium alloy TC17 with microcrystalline alumina grinding wheel

Grinding experiments were conducted on titanium alloy TC17 with microcrystalline alumina and white alumina grinding wheels separately to study their grinding performance,such as surface quality and grinding force.The results show that surface ground by microcrystalline alumina has better quality,with surface roughness value decreased by 0.14 μm and grinding force decreased by 10%.Single factor tests were conducted to study the influence of grinding parameters on the grinding force of microcrystalline alumina wheels.It is found that the optimal parameters for grinding TC17 are linear speed of the wheel v_s=27 m/s,grinding depth a_p=0.01 mm and workpiece infeed rate v_w=12m/min.In the end,multiple linear regression analysis is carried out on test data of grinding force,and the regression models of normal and tangential forces of grinding are established.
