| General note | With exigent demand, and requirement of miniature products in medical, aerospace, and<br/>electronic industry, it is growing need to introduce new low cost, high quality, and high accuracy<br/>process capable of producing miniature products. Despite of many advantages and very suitable<br/>process for miniature devices, there are still some challenges in micro- milling. Formation of burr<br/>is one of the major problems which is being faced in micro milling. Extensive research has been<br/>conducted to minimize its formation. Titanium alloys possesses excellent properties which make<br/>them first choice for medical & aerospace applications. Titanium grade-5 (Ti-6Al-4V) alloy<br/>abounds in literature for most of the applications but there are some applications, where due to<br/>excellent properties of titanium grade 9 (Ti-3Al-2.5V), it becomes an attractive choice for<br/>precision production applications i.e., pacemaker in medical and honeycomb in advanced<br/>aerospace applications.<br/>The current work in this research study aimed to analyze the influence of various process<br/>parameters of micro milling operation on the surface quality, burr formation and tool flank wear<br/>in micro machining of titanium grade 9. Three levels of each process parameter were taken into<br/>consideration. Process parameters were statistically analyzed by employing ANOVA (analysis of<br/>variance) for key process parameters. Results of this study show that feed rate is major factor<br/>influencing the surface roughness & burr formation with contribution ratio of 62.96 % & 54.05 %<br/>respectively, whereas cutting speed and depth of cut were also significant factors for surface<br/>roughness with contribution ratio of 20.32 % & 9.27 % while contribution of these two parameters<br/>for burr width stood at 21.63 % & 10.91% respectively. Cutting speed is major influencing factor<br/>for tool flank wear with contribution ratio of 54.02 % while feed rate contribution stood at 33.18<br/>%. Depth of cut found insignificant factor for tool flank wear. Feed rate was only significant factor<br/>in length of burr with contribution ratio of 45.14%. Confirmation tests were conducted at optimum<br/>parameters which showed minimum value of burr width, length, surface roughness and tool flank<br/>wear. |
