Description
A method was developed to integrate basic force control functionalities into a CNC milling machine for friction stir welding (FSW) by using a standard CNC controller, optimum control parameters for various FSW conditions were identified and the force controller was evaluated. The methodology incorporated the extension of a position controlled feed drive by a flexible programmable force controller. Experiments were undertaken to produce force controlled bead on plate welds in 5182-H111 and 6060-T66 alloys at spindle speeds of 600-1400 rpm and feed rates of 100-600 mm/min. For each parameter set, an optimum controller value was determined and the relationships between FSW conditions and suitable control settings were derived.
