Experimental Investigations for Assessment of Carbon Emissions and Tool Temperature in Dry Turning Operation Using Al1070 Alloy

Dry turning operations are required to be performed during production to achieve sustainable development goals as per environmental protection guidelines. In such machining operations, there is no need of supply of mineral based cutting fluids (MBCF) which creates problems of environment contamination and health risks to operators such as lung cancer, eye irritation and skin diseases etc. Al1070 alloys are currently used in construction industry, transport, communication cables and refrigerator cabinets as light weight structural material. The main objectives of the present study are to explore the dry turning operation (without use of MBCF) using Al1070 alloy. The X-ray fluorescence elemental analysis was performed to check composition of MBCF. Several harmful elements such as phosphorus, chlorine, and zinc dialkyl dithiophosphate were present which create high health risk to operators in turning operation with MBCF. The work piece, the cutting tool, the electricity consumption, and the recycling of the chips during the turning process contributed to the total carbon emissions. Significant positive impacts on environment have been achieved in dry turning operation as compared to tuning with MBCF. 19.85% reduction in carbon emissions and 37.12% reduction in tool temperature were achieved in dry turning operation with minimal tool wear and surface defects.
