The study presents the measurement and analysis of transient cutting forces of a rotating tool such as milling cutter from the tool side by means of the improved optical data transmission device. The measured cutting forces by the device are confirmed to correspond to those from workpieces by use of a conventional dynamometer. After disengaging from workpieces, the tool vibrates in the first natural frequency. In addition, transient cutting forces in up-milling, downmilling and up-and-down-milling are found to dominantly contain the component of the first natural frequency, independent of cutting speed, feed rate and depth of cut.
