【 摘 要 】

The paper reports on the friction stir processing of aluminium alloy plates having a thickness of 2 mm using a reconfigurable vertical milling machine. In-house design and manufacturing of the tools were done using tool steel. A backing plate with fixture mechanism was designed for holding the plates in the vice of the machine. The tool was rotated using the milling machine at different speed ranging from 710 to 1400 rpm under a transverse constant speed of 80 mm/min. The average hardness and tensile strength of the produced weld joints were further analyzed for different tool rotational speeds. An optimum rpm of the spindle was found out for defect free joints.
