The Effect of the Operating Speed and Wheel Characteristics on the Surface Quality at Creep-Feed Grinding Titanium Alloys

Abstract:

The paper dwells upon flat creep-feed grinding of grooves in Ti6Al4V workpieces. Those were machined with high-porosity silicon carbide wheels of I, H grades at a speed of 20-30 m/s. Machined surfaces were analyzed using a Versa 3D electron microscope. The paper demonstrates the formed morphology of ground surfaces along the workpiece. Higher-speed grinding results in greater concentrations of silicon on the machined titanium alloy surface. Altering the characteristics of the abrasive tool does not have a significant effect on the concentration of silicon on machined surfaces. The paper analyzes how the grade of wheel and the grinding speed affect Ra surface roughness parameter. The article demonstrates the difference in grades of wheels along the surface, at the stage of constant length of arc and the stage of exit.
