Selection Of

In the process of cutting, often the selection of cutting parameters is done considering empirical methods. This approach is more expensive and does not usually lead to the best solutions. Numerical methods for simulating the chip formation have been under development over the last thirty years. The aim of the present research is to compare models based on rheological properties of metals with 2D Finite Element Models of chip formation process.

On Chip

Finite element analysis (FEA) is a numerical technique in which product behavior under various loading conditions is predicted for ease of manufacturing. Due to its flexibility, its receiving research attention across domain discipline. This chapter aims to provide numerical investigation on chip formation in micro-end milling of Ti-6Al-4V alloy. It is widely used for medical applications. The chip formation process is simulated by a 3D model of flat end mill cutter with an edge radius of 5 μm. Tungsten carbide is used as a tool material. ABACUS-based FEA package is used to simulate the chip formation in micro-milling operation. Appropriate input parameters are chosen from the published literature and industrial standards. 3-D orthogonal machining model is developed under symmetric proposition and assumptions in order to reveal the chip formation mechanism. It is inferred that the developed finite element model clearly shows stress development in the cutting region at the initial stage is higher. It reduces further due to tool wear along the cutting zone.
