Investigation of a novel green internal cooling in turning application

Cutting temperature have significant influence on workpiece quality, tool life and manufacturing productivity. Temperature of a tool must be reduced to an acceptable range in metal cutting process. Conventionally, cutting fluids were commonly used in machining to reduce cutting temperature. However, cutting fluids pollute environment and increase environmental regulations and the related coolant disposal and treatment costs. Dry or green machining has been aggressively pursued in the manufacturing industry in recent years. In this study, a novel green internal cooling method is presented, which combine coolant channel and heat pipe cooling. 3D Finite Element Method using ANSYS software is employed to thermal and structural static and dynamic analysis in a turning process to check the feasibility and effectiveness of the internal cooling system. The numerical simulation results demonstrate that the novel cooling method could effectively reduce tool temperature.
