Different products are manufactured using the machining process. It is a value addition process in which material is removed from parent material in the form of chips to make a product or a component. Machining processes are of two types, namely conventional machining and non-conventional machining. The fundamental principle of conventional machining like drilling, milling, turning, shaping and non-conventional machining like ultrasonic machining, chemical machining, electron beam machining is manufacturing a product by removal of material. Cutting parameters play a crucial role in machining processes. They have a significant effect on cutting forces generated during the machining process, which will in turn affect the machining induced residual stresses. In this current work the force variation was determined using a piezo-electric dynamometer, when the different machining parameters were varied. The paper aims at examining the cutting forces generated during milling of Aluminium 7050 T-7451. Aluminium is chosen as it is very widely used and has many applications in the aerospace industry. Using appropriate techniques, a mathematical model which can predict the cutting forces for different cutting parameters was modelled. Future work involves investigating residual stresses.
