Abstract

Drilling is one of the material removal process and recently the working scale has entered the micro level. Micro drill life which is normally predictable in the conventional scale machining, remains uncertain to be defined as the failure mode of the micro-sized tool is completely different from the conventional ones. This research is initiated to investigate the distribution of micro tool life when drilling Titanium Ti-6A1-4V. The purpose of this study is to investigate the tool life performance based selected on cutting parameters; spindle speed, depth of cut, feed velocity and the drilling technique. These parameters were then evaluated using Taguchi method to identify the best parameters’ combination in achieving optimum tool life. The result shows that cutting depth is the most significant factor which influence a micro-tool life. The trend however, remains uncertain throughout the experiment as when the best combination parameters was employed, higher tool life could not be assured. [ABSTRACT FROM AUTHOR]

Abstract

Milling is widely used metal removal process in manufacturing industry that involves generation of high cutting forces and temperature. Lubricants become important in order to reduce the cutting force and temperature for better machining processes and performances. Conventional cutting fluid has some limitations. The applications of conventional cutting fluid create some techno-environmental problems like environmental pollution, biological problems to operators and water pollution. Application of solid lubricant in milling has proved to be a feasible alternative to the conventional cutting fluids. The present work investigates the effect of boric acid as solid lubricant towards machining performances such as tool wear and surface roughness. The results indicate that boric acid can improve the cutting processes and performance compared to conventional cutting fluid. [ABSTRACT FROM AUTHOR]
