Research of Surface Finish during Titanium Alloy Turning

Abstract

The paper presents research of titanium alloy (Ti6Al4V) and pure titanium turning with sintered carbide tool of rounded shape. Finish machining was performed on the work piece in the form of a fragment of ball. Several roughness parameters were chosen for the purpose to the surface finish analysis. Results were compared for the pure titanium and its alloy. The test stand for research was consisted of the precise CNC lathe with a special devices, like force dynamometer, roughness and roundness measurement systems. In the work a special attention was paid on the influence of the cutting data (cutting speed vc , feed f and depth of cut ap) on the surface quality.
