Grinding Force of Ti-6Al-4V Titanium Alloy during Dry Belt Grinding

Ti-6Al-4V titanium alloy was grinded under dry belt grinding conditions and the effect of working parameters on grinding force was analyzed.Grinding status and worn surface morphology of the workpiece were measured by using dynamometer,three-dimensional digital microscope,profilograph and microhardness tester.Optimization solution of the belt grinding process parameters was proposed.The results show that in the dry belt grinding conditions,the grinding force increased with the increase of the grinding depth and feed speed of and the decrease of the belt speed.Surface roughness of the alloy was not more than 0.35 μm,when the belt speed was 15 m·s-1,feed speed was 315 mm·min-1 and grindding depth was 0.025~0.1 mm.
