TOOLING PRODUCTION

Rogov V. A., Gorbani S. — Damping properties analysis of a split lathe tool with composite material in its construction

This paper introduces a new design of the combined lathe tool; and applies epoxy-granite, possessing high damping capacity, in the tool holder of the lathe tool in order to reduce vibration during cutting process and increase tool life. It has been used a set of three types of tool holders: the standard all-metal tool, the tool with horizontal holes arranged in a chess-board pattern, and the tool with horizontal holes arranged in a chess-board pattern and tilled up with composite material. Three different types of epoxy-granites with different damping capacity were used: normal, rigid and plastic epoxy-granites. The computer simulation of the models was developed and static and dynamic analysis of the tools were studied; as a result the displacement of the tool point, natural frequency, maximum vibration displacement of cutting edge were obtained. The result revealed that as the overhang of the tool increases the displacement of the tool point increases and natural frequency decreases; the model-filled with normal epoxy-granitc has the lowest frequency compared to other models; the application of epoxy-granite in the tool holder has reduced vibration and increased tool life.
