Determination of the dynamic behaviour of micro-milling …
The dynamic behaviour of milling processes can be analysed using process simulations based on measured frequency response functions. However, the determination of these functions for micro-milling processes is challenging due to small tool diameters of 1 mm or less, the influence of higher spindle speeds on the dynamic behaviour, and runout errors.

Machinablity improvement with ultrasonic vibration–assisted micro-milling
During the micro-milling process, the spindle speed is 20,000 r/min combined with the two-edge milling cutter. Hence, the corresponding rotation frequency is 666 Hz. In order to ensure the accuracy of data acquisition, the dynamometer sampling frequency is 1 kHz, higher than the rotation frequency of micro-milling.
