Studies on Process Parameters in End Milling Operations of Aluminium Alloy

Aluminum is one of the most widely used metals in the construction of aero planes, truck wheels, screw machine products and turbine manufacturing industries. Accurate prediction of process parameters is important in controlling the dimensional accuracy of thin walled aeroplane components. The effects of various process parameters such as pressure and friction acting on the cutter- chip interface, cutter geometry on chip flow and specific cutting energy are studied. Pressure and friction acting on the cutter- chip interface decrease with the increase of feed rate. Chip flow angle increases with the increase of feed rate. Effect of cutting speed on the pressure and friction parameters for aluminium has a negligible effect on the process parameters. Specific cutting energy decreases with an increase in feed rate 1
