Abstract

The abrasive waterjet technology is a cutting process without heat. No smoke and toxic occurred during the cutting process. The cut surfaces of work pieces are clean and the quality is based on accordingly the configuration parameters. The research studies the cutting mechanism and optimized parameters for the cut surface quality. For reduce the loss of material and amount of abrasive garnet used in the process. The experiment will cut the Nickel based super alloys grade Inconel 718 thickness 6.35 mm. Design of experiment and determine the main parameters of cutting operation with Water pressure,


Abrasive flow rate and Traverse speed. The analysis of the results obtained has been performed by Taguchi method. In order to identify the process parameters that is significant in affecting with the taper angle. The analysis of variance (ANOVA) has been carried out to estimate the relative contribution of each control factor. The cutting results showed that parameters are affected with taper angle as a function of kinetic energy loading.
