Investigation of Experimental and Statistical (Respond Surface Method and Grey Relational Analysis) of Surface Roughness, Vibration and Enerrgy consumption Values of Titanium Alloy During Machining

This study aims to explain the interaction between results measured in turning operation. For this purpose, Ti 6Al-4V alloy workpiece was machined on CNC lathe. Surface roughness (Ra), vibration and energy consumption values were determined by turning. Experimental analyzed statistically. Response surface method (RSM) grey relational analysis used statistical analysis. In RSM analysis, regression equations, ANOVA, contour graphs, pertubation real prediction % contribution most significant factor, optimum parameters, it is that effective parameter roughness, feed rate. Grey steps are examined.
