Modelling the cutting forces in micro-end-milling using a hybrid approach

摘要: This paper presents the development of a cutting force model for micro-end-milling processes under various conditions using hybrid approach. Firstly, finite element (FE) orthogonal micro-cutting with round edge is developed medium-carbon steel. A number analyses (FEA) are performed at different uncut chip thicknesses and velocities. Based on FEA results, coefficients extracted through nonlinear algorithm to establish relationship thickness speed. Then, integrated into mechanistic model, which can predict forces conditions. In order account effect, an effective rake angle employed determination force. comparison prediction experimental measured has shown that method provides accurate results.
