This study is based upon Experimental process about Material Removal Rate (MRR). All the data is based on Material removal Rate (MRR) using wire electro-discharge machining (WEDM) for fabrication of Micro Channels. Experiments were designed using DOE (Design of Experiments) and Response Surface methodology for optimization of Material removal Rate (MRR). DOE gave certain number of experiments to perform depending upon the number of parameters selected. The software used is MINITAB16.1. WEDM involves several machining parameters such as pulse-on time, pulse-off time, peak current, wire feed rate, servo reference voltage, wire tension, and dielectric flow rate. However for this work the variables such as pulse-on time, pulse-off time, wire tension, and dielectric flow rate were considered as the input (control) parameters. The experiments were conducted using brass wire of diameter 0.25 mm; on work piece material of Aluminum 6061 having dimensions 22mm×22mm×5mm. The micro channels of size 0.5x0.5 mm were fabricated. Micro channels were fabricated on CNC WIRE EDM EPULS40ADLX machine.
