A Study on Machining of the Self-Wiping Co-Rotating Twin Screw

This paper describes screw tool design and machining method witch is able to design tool profile and 3-dimensional geometry for screws in self-wiping co-rotating twin screw extruder. The geometric features of screws for co-rotating twin screw extruders are developed from kinematic principles. Closely self-wiping screw segments are manufactured in universal milling machine by using designed screw tools. It is shown that experimental results verified the closely intermeshing condition in twin screw.
