Abstract. In today’s manufacturing techniques, hard turning became the most rising technique to cut high hard materials like high chrome white cast iron (HCWCI). The use of Cubic boron nitride (CBN), Polycrystalline Cubic boron nitride (pCBN) and Carbide tools are most appropriate to shear the metals but are uneconomical. These materials are cut in dry condition, which results in lower life and can be enhanced by minimizing the tool temperature. The research study exposes effective tool cooling systems that can improve tool life and machinability characteristics, also proper selection of cutting parameters to control the cutting temperature. The main aim of this paper is to develop an ideal cooling system to control tool temperature, thereby minimizing the tool wear rates and cutting forces. In this research work, experiments were conducted on annealed high chrome white cast iron using carbide inserts. Intricate cavities were made on the toolholder body for easy circulation of cold water. Statistical tools were used to carry out the experimentations and its analysis. The result confirms, intercooling system minimizes the cutting forces and tool wear at considerable rates compared to non-intercooling system.
