Optimal Material Removal and Effect of Process Parameters of Cylindrical Grinding Machine by Taguchi Method

In a developed economy, market for any product is generally highly competitive. To be successful in such a condition producer has to provide output which has distinctive advantages over others e.g. innovative designs and ideas, extremely good quality related to aesthetics and functional aspects, etc. Quality is a good tool for competition. It is necessary for customer's satisfaction and also for meeting societal obligations. To fulfill this goal, all these qualities have to be built-in in the product through systems approach and that is the main concept of total quality control. For achieving quality we have to start right from the inception stage of the product and continue till product is giving service. In past a lot of consideration was given for controlling quality at manufacturing process stage and checking incoming and outgoing material in the form of inspections. The new approach, which is emerging, is based on Zero Defect system, quality control circles and off line quality control. Out of these, Taguchi’s method of off-line quality control is most comprehensive and effective system. It gives a design of product, which is requiring very less on-line quality control. Taguchi's approach has both philosophical and mathematical contents. The methodologies developed to implement his ideas are known as Taguchi methods. This research outlines the Taguchi’s Parameter Design Approach, which has applied to optimize machining parameters in Cylindrical Grinding Process. The grinding parameters evaluated are cutting speed and depth of cut. An orthogonal array, signal-to-noise (S/N) ratio and analysis of variance (ANOVA) are employed to analyze the effect of these grinding parameters. An orthogonal array has used to plan the experiments. The raw data analysis and signal-to-noise ratio analysis have employed to analyze the influence of grinding parameters on material removal rate during grinding process. The purpose of the analysis of variance (ANOVA) is to investigate which design parameters significantly affect the quality characteristic. This procedure eliminates the need for repeated experiments, saves time and conserves the material as opposed by the conventional procedure. Experimental results are provided to confirm the effectiveness of this approach.
