Design Experimentation & optimization of CNC Flame cutting machine parameter’s

Abstract

Last Ten years there is tremendous research in machining and development in technology. With increase in competition in market and to attain high accuracy now a days the non-conventional machining are become lifeline of any industry. One of the most important non-conventional machining methods is CNC flame Machining. Its high accuracy, finishing, ability of machining any hard materials and to produce intricate shape increases its demand in market. In thesis work literature has been studied in context to parametric optimization of CNC flame Machining. In order to attain target and optimum results, Taguchi method employed. The appropriate orthogonal array has been selected as per number of factors and there levels to perform minimum experimentation. The work pieces of mild Steel materials were used for experiment purpose. The optimum value has been determined with the help of main effect plot and ANOVA table. The Regression value for kerf and Surface Roughness (Ra). Confirmation test have done to confirm the value estimated through the observation. The minimization for kerf & surface roughness run was done by using the setting of different Gas pressure, 400-700 mm/min (cutting speed) and 3.0 mm (arc gap). Experimental results are provided to confirm the effectiveness of this approach.
