In robotic milling, at the presence of the low frequency modes, introduced by the robot structure, the process damping effect may not be observed as in CNC milling. So that, high speed machining may be favorable compared to low speed machining for increased chatter-free removal.In this study, the process damping effect is investigated in robotic milling through experimental results. Stability diagrams are compared to the experimental results to highlight the conditions where the flexible dynamics of the robot may hinder process-damped regions. Favourable high-speed machining regions are shown, and conclusions are derived for future research.
