| Summary: | Machining process involves many process parameters. Achieving accurate dimensions,
good surface quality, and maximized metal removal are of utmost importance. This
research work describes the optimization of cutting parameters for the surface
roughness in CNC turning machining with aluminum alloy 6061 material. Controlling
the required surface quality is necessary. In this study, Taguchi method is used to find
the optimal cutting parameters for surface roughness in turning. L-9 orthogonal array,
signal-to-noise ratio, and analysis of variance are employed to study the performance
characteristics in the turning operations of aluminum alloy 6061 using uncoated inserts.
A precise knowledge of these optimum parameters would facilitate reduction of
machining costs and improve product quality. The current study on turning process
applies a response surface methodology on the most effective process parameters,
namely, feed, cutting speed, and depth of cut, which are optimized considering the
surface roughness and material removal rate. The results of the machining experiments
were used to characterize the main factors affecting surface roughness by the Analysis
of Variance (ANOVA) method. Feed rate and speed of cutting founds to be a most
influencing parameter for the surface roughness in the shaping process whereas depth of
cut is found to be significantly affecting the MRR. |
