This paper proposed the design of a desktop reconfigurable machine tool for the different demands in the process of micro manufacturing. By contrast to traditional types of machine tools, the unique structure of reconfigurable machine tool makes it energy-saving, efficiently and the type of work can be rapidly changed in response to products change. The reconfigurable machine tool function can be switched between turning and milling with the exchange of mechanical units and modules. To ensure the high accuracy of this machine tool, the dynamic and static performance of turning unit and milling unit were analyzed with finite element method. The results of analysis were applied to make an optimized design parameters of machine tool. The desktop reconfigurable machine tool has a good structural performance according to the static and dynamic analysis results. The gantry type structure posses good scalability and it provides a flexible stage for the research of micro cutting
