Abstract—Micro-machining is the basic technology of micro-engineering for the production of micro-sized parts and components. Miniaturization of machine tools to size compatible to target products without compromising machining tolerance lead to enormous saving in energy, space and resources. The paper deals with optimization of micro milling parameters of AL-6082. Generally micro milling processused inBio-medical, Aeronautical, Microelectronic industries. Recentlymicro milling widely used for the manufacturing industries due to its capability of producing tedious geometric surfaces with good accuracy and surface finish. In this experimental work micro milling experiments are conducted in Micro milling machine using 0.5 mm diameter end mill at spindle speeds up to 10,000 rpm on machining of AL-6082. The analysis of the result shows that the optimal combination for higher Metal Removal Rate (MRR) is medium cutting speed, high feed rate and high depth of cut. Using Design Of Experiment (DOE) concept, other significant effects such as the interaction among micromilling parameters are also investigated by using ANOVA method.
