Investigations on forming behavior of AA8011 alloy sheets in friction stir incremental forming

Abstract

The solid-state metal forming technique known as quotFriction Stir newlineIncremental Formingquot (FSIF) uses mechanical deformation and frictional heat newlineto gradually create complicated structures. This procedure involves inserting a newlinerotating tool into a workpiece and slowly moving it along the material s newlinelength, which causes the material to deform gradually. The FSIF technique is newlinefrequently utilized in the manufacturing of numerous elements, including newlineconsumer goods, aerospace structures, and automotive components. newlineThe FSIF process has a number of advantages over more traditional newlinemetal forming techniques. There is no melting or recrystallization of the material newlinebecause it is a solid-state process, which enhances the materials qualities like newlinestrength and fatigue resistance. Due to its ability to produce precise, high-quality newlinecomponents with improved material properties, it is a popular choice across a wide newlinerange of industry sectors. newlineThe main objective of this work is to design and development of newlinedifferent coated tools for improving surface quality. In this work, a novel newlineattempt was made to use three different tool coatings to increase the desired newlinesurface quality while minimizing tool wear. Process variables such spindle newlinespeed, step size, and table feed were taken into account, along with the two newlineresponse parameters constituting force and surface roughness, in order to newlinedetermine the ideal values. A full factorial design was used to conduct a total newlineof 27 experiments. newline newline
