Abstract

The emphasis on structural design of miniaturized machine tool (mMT) used in micro-machining process is different from that of conventional machine tool due to requirement of higher precision and stable performance. In this paper, structural modeling and simulation of 3-axis vertical micro-end-milling system is presented. Based on different components combination, three models of linear multi-degree-of-freedom vertical milling systems are constructed theoretically using high precision stages. The most suitable model is chosen by volumetric error calculation. Finite element method (FEM) is used for simulation of those numerical solid models. Static and dynamic analysis with different joint stiffness and loads is simulated by ANSYS. Prototype model is assembled according to the selected structure. Finally, surface roughness of the bottom of micro slots, which are machined by prototype model, is analyzed to verify the performance of mMT.
