N2 - Vibration-assisted milling (VAMILL) has been widely applied, mainly on the workpiece side. However, its applications on the tool side are quite rarely reported. It is relatively easy to implement vibration-assisted milling on the workpiece side because it does not require redesigning the milling machine. It can be achieved by designing a vibrating worktable system that is suitable for the workpiece. This system still has drawbacks; namely, it is not practical to be applied to 5-axis milling machines due to the kinematics limitation of the vibration-assisted milling system, which cannot follow the tool path. Another drawback is caused by the condition when the workpiece is replaced with different materials or dimensions. It requires adjustment of the design frequency of the system due to changes in the mass and stiffness of the workpiece system. For these reasons, the longitudinal-torsional vibration-assisted milling system (LT-VAMILL) applied to the tool is more flexible and effective. In this study, an initial design of a novel longitudinal-torsional vibration-assisted milling system is presented. The vibration-assisted system applied on a tool side using an ultrasonic horn to increase piezoelectric ceramic rings' longitudinal displacement effect and transform the longitudinal displacement into a longitudinal-torsional composite vibrational mode at the end tip of the system. The system design, such as the overall design length of the longitudinal-torsional vibration-assisted milling system, is designed so that it can be implemented on a Hadia Micromill-5X milling machine with limited working space or working envelope of the machine, especially in Z-axis. The two ultrasonic horn designs proposed are still in a simple form, namely stepped and cylindrical-conical horns, for reasons of ease of design and manufacture. In addition, three methods of connecting the tool to the ultrasonic horn are also proposed.
