Abstract: Milling is a very commonly used manufacturing process in the industry due to its versatility to generate complex shapes in variety of materials at high quality. Due to the advances in machine tool , CNC, CAD/CAM, cutting tool and high speed machining technologies in last couples of decades ,the volume and the importance of milling have increased in key industries such as aerospace ,die/ mold, automotive and component manufacturing. But however the unstable machining (namely chatter vibration) is one of the main limitations for high speed machining which shortens the tool life and decreases machined surface quality. In this paper static and dynamic analysis of end mill tool with different geometry is carried out by Finite element analysis (FEA), also some practical equations are developed to predict the static and dynamic properties of end mill tool And the results obtained by both the methods are nearly same. However in case of static analysis amount of deflection of tool for a particular value of cutting force can be easily determined, while in case of dynamic (modal) analysis natural frequencies and mode shapes can be determined.
