Abstract
Quality is inversely proportion to variability. In the other words as variability reduces, Quality improves. This approach has been used in this work. In the present work variability in the dimension of the manufactured part has been reduced. Reduction in the surface roughness as well as tolerance is the basic aim of this work. The optimization of input parameter has been done for improvement of quality of the product in turning operation on CNC machine. Feed Rate, Spindle speed & Depth of cut are taken as the input variables and the dimensional tolerances and the surface roughness are taken as quality output. In the present work Taguchi L9 Array has been used for design of experiment for optimization of input parameters in turning of ASTM A387 Alloy Steel. It was found that the spindle speed is key factor for minimizing the dimensional variation and feed rate is most effective input parameter for minimizing the surface roughness
