Increased Productivity due to Jerk-decoupled Feed Axes of the 5-Axes Milling Machine 'Neximo'

摘要

With the development of highly dynamic machine tools, flexibilities of the machine structure represent a major challenge in machine tool design. High machining forces and accelerations induce static and dynamic deflections of the machine frame which affect the accuracy of the machine negatively. To master this conflictive aim of high dynamic feed drives and simultaneously increased machining accuracy, the IFW developed the 5-axis machine tool prototype "Neximo" with jerk-decoupled x- and y-axes. This paper presents the results of the performed vibration measurements and the achievable increased productivity in machining processes by higher jerk limits due to the applied jerk decoupling technology.
