Abstract�� ����The process to grind ball-end cutter is the most complex in all the tool grinding processes, especial for the rake faces and flank faces of the cutter. They are the research hotspot now. The structure of the virtual axis machine is different from the conventional machine. So its movement control characteristic is different. These characteristic must be taken into account. Two machining models were researched,which were the Archimedes spiral curve and the circle path curve of the ball end cutter rake faces. The position control parameters were calculated when grinding these two curve models. Based on the machining curve model the processing technology was presented according to its special features of the 6UPS machine. The processing technology proposed can simplify the machining model and increase machining efficiency and precision.
