Abstract
Milling chatter significantly affects machining productivity, and methods to eliminate chatter caused by milling cutter dynamics are limited due to space constraints and the rotation of the milling cutter. This study investigates the impact of fluid-induced damping effect on chatter stability in milling operations and proposes it as an easy to implement and effective method to improve chatter stability caused by a cutter's vibration mode. The approach utilises a viscous fluid, silicone oil, filled into internal coolant channel of the cutting tool to improve stability by increasing the damping. Both modal and milling tests were conducted for the tool with and without silicone oil. The results show that stability can be significantly increased by this method presenting it as a viable chatter suppression technique. The results show a significant improvement in stability by presenting the method as a practical and cost-effective chatter suppression solution. Its ease of implementation makes it attractive for industrial use.
