Abstract: Friction stir processed on AA5052 aluminium plates is executed by three-factor three levels Box-Behnken pattern in response surface methodology. It is initiated that the processing parameters such as rotational speed of tool, traverse speed, axial load accept an essential part in selecting the processing attributes. The advanced parameters that prompted the most extreme tensile strength in FSP on AA5052 were resolved. The predicted outcomes were then contrasted with those tentative values. The outcomes show that there is great understanding between the predicted and estimated values. Response plots created from the numerical models are used to translate the communication impacts of the processing parameters on the response variables. Competence of the created models is approved utilising analysis of variance (ANOVA) procedure. The 'MINITAB' programming was utilised for regression and graphical studies of information gathered. Analysis of variance was promoted to check the effectiveness of the model. Box-Behnken matrix in response surface methodology with three factors three levels and 15 runs was used to promote the link between the FSP parameters (processing speed, tool rotational speed and load) and the responses UTS, yield strength and micro hardness were created.

Keywords: rotational speed; traverse speed; axial load; RSM.
