Experimental investigation and Taguchi optimization of turning process parameters for glass fiber reinforced plastics (GFRP)

The recent research work has been carried out under the parameters of cutting speed, feed rate and depth of cut in which the material removal rate, machining time and the surface roughness on the glass fiber reinforced plastic (GFRP) composite material during the turning process was analyzed. The objective of this work, is to focus the machining characteristics of GFRP are inspected under the Taguchi Design method. And hence the experimental results are carried out as per the Taguchi experimental design and an L9 orthogonal array is observed through the design of experiment and it is used to study the influence of surface quality parameters. This method is to achieve the optimal control factor of the machining process parameters such as surface roughness, machining time and material removal rate. And finally to determine the optimal levels of the parameters the analysis of means (ANOM) will be performed. In addition to identify the level of importance of the machining parameters the analysis of variance (ANOVA) has to be employed. These analysis results revealed that the major contribution of the process parameter such as surface roughness was the most influential factor on the feed rate, and for machining time, speed is the major influencing factor and for material removal rate, Depth of cut (DoC) is the main influence factor are observed.
