A capsule-type modular machine tool was developed, which was capable of multifunctional processes with a single setup. This mechanism was designed according to the concept of a reconfigurable machine tool (RMT), which can transform from a machining center to a lathe, and is capable of multiple functional processes, such as laser, milling, and grinding processes. After addressing the kinematics of the machine, a static structural analysis was performed and some ribs were added to enhance the stiffness. A frequency response function (FRF) simulation was conducted on the modified machine and natural frequencies were determined to avoid resonance in processing. Then, an FRF test was performed to find the actual natural frequencies, to confirm the simulation results. After investigating the natural frequencies, high-speed machining was performed to make 300 μm sized patterns.
