Abstract

The machining of a long trapezium spline is difficult due to its stiffness. In this paper, a special cold extrusion technique has been adopted on the basis of analyzing its three-dimensional velocity field and simulation using the software programme Deform-3D 5.0 to make a qualified trapezium spline ofΦ12× 840 with 16 teeth.
