Performance of Shot Peening Process, Shot Peening Parameter


Fatigue failure is a result of a crack initiation and propagation, in consequence of a cyclical load. In aeronautical components as landing gear the fatigue strength is an important parameter to be considered in manufacturing of it, as well as the corrosion and wear resistance. The major applications of the shot peening are related to improvement and restoration of properties and reliability of machine elements by increasing their surface hardness, tensile strength, surface finish, impact strength, fatigue strength etc. The improvement of properties depends on the intensity of shot peening process. The intensity can be varied by regulating the size of shot, the hardness of shot, the speed at which was fired, the length of time, the distance of nozzle from the surface and the work exposed to the shot. Basically there are so many input and response variables discussed in the previous works but the availability and cost are the important factors considered in this work for the variables. The shot peening was carried out on the EN9 component with the fixed diameter shots and then the changed parameters and properties were discussed with the help of different tools like DoE and optimization were carried out in Response Surface Methodology in MINITAB14, ANOVA and Regression for checking the model for adequacy of the different factors, Response optimizer gave the final optimized combinations of the input variables to get the maximum benefit of responses. From the experimentation it is found that out of three input parameters velocity of peening was observed as most significant factor. The important and primary response parameter arc height gave the significant set of input parameters with their appropriate levels.
