STUDY ON CUTTING FORCES AND SURFACE FINISH DURING END MILLING OF TITANIUM ALLOY

摘要

This paper investigates numerical and experimental study of end milling of titanium alloy Ti-6% Al-4% V using carbide insert based cutting tool. The experiments were carried out under dry cutting conditions. The cutting speeds selected for the experiments are 20,30,40,50 mmin~(-1). The feed rates used in the experiment were 0.02, 0.04, 0.06 and 0.08 mmrev~(-1), while depth of cut is kept constant at 1.0 mm. For conducting the experiments single insert based cutting tool is based. For a range of cutting speeds and feeds measurements of cutting force, surface roughness and cutting temperature have been recorded. From the experimental study it can be seen that cutting speed has the significant effect on temperature when compared to feed/tooth. Further it is also found that cutting speed of 30 m min~(-1) and feed rate of 0.02 mm rev~(-1) could be used for machining Ti alloy. Moreover the experimental and numerical cutting force values are compared.
