Studies on the Effect of Output Parameters on Productivity When Turning Titanium Alloys

The article presents the results of studies on productive turning of titanium alloys which are widely used in different industries, including the aircraft one. Methods used to achieve maximum productivity of the manufacturing system were analyzed. The factors deteriorating cutting productivity were analyzed. The effect of output parameters on cutting productivity was studied. Cutting power was estimated under various cutting modes. Temperatures were analyzed under various cutting modes and their effect on the material and the cutting tool was studied. A decrease in cutting speeds was investigated. Turning cutters with replaceable carbide inserts with a protective coating were used. Cutting forces and temperatures were measured. Cutting power was calculated by measuring cutting forces. The effect of machining modes on temperatures and productivity was analyzed. The dependences of productivity on cutting power were determined. It was shown that VT20 and VT22 titanium alloys are cut in a different way. Effective methods for improving turning productivity were developed. The directions for further research on titanium alloy turning productivity were described.
