Finite Element Simulation and Experimental Study on Micro-Milling Cobalt-Based Alloy

Abstract:

Elgiloy is a cobalt-based alloy with excellent physical and chemical performance, which is used widely in medical and industrial applications. In this paper, the professional finite element analysis software for metal cutting is used to establish the finite element simulation model of micro cutting this kind of cobalt-based alloy, and the effect of feed rate, which is considered as the most important processing parameter, on the cutting force of micro cutting Elgiloy is analyzed. The cutting force measurement system based on ultra-precision micro milling machine tool is established for experimental study on the cutting force of micro milling Elgiloy by using ultra-fine gain tungsten carbide micro milling tool. The cutting force is measured with different feed rate parameters and the influence of the parameters on the cutting force is analyzed. The simulation and experimental results show that the trends observed at the micro scale are the same as the trends for machining at the macro scale, which implies that the Elgiloy material behaves in a similar manner at both length scales.
