Performance Measurement of Drilling Process using Micro Textured Drill on Titanium Alloy

Abstract

In manufacturing industry, machining process and its environmental effect analysis are very important for enhancement of sustainability analysis. In drilling process, the heat is generated due to friction, and this heat can be removed by the application of cutting fluid. The cutting fluid serves as an agent to cool the cutting tool and lubricates between the tool-chip and tool-work piece interface, but it also produces environmental pollution and other operator health issues. Hence, various research works are carried out to achieve sustainable machining by using development of new coated tools, minimum quality lubrication (MQL) and cryogenic machining. It has been observed that in recent times some research works are focused with different types of textured surface on drill tool either on flute or margin surfaces for improvement of tribological properties and sustainable improvement. These textured surfaces are also known as micro grove, micro pool, self-lubricating, self-cooling cutting inserts filled with solid lubricant which has been found, the application of solid lubricant on textured surface is observed to provide lubrication effect. In this work, the application of margin and flute textured drilling tool on drilling of titanium alloy. Input parameters include spindle speed, feed rate and cutting conditions. Output parameters surface roughness, and temperature. The result revealed that textured drill tool provides better machining performance. It also leads to sustainability in manufacturing process.
