Abstract

The work presented in this paper provides the basis for an extension of conventional orbital forming to a new, flexible forming process. A hydraulically actuated hexapod is used to move a swage in order to extrude a work piece towards a desired shape. This paper presents an analytical model of the actuators and the dynamics of the hexapod. This model is used for developing a cascaded position control law, and for developing a simulation environment representing the machine and the work piece in an entire forming process loop. The design of the machine is briefly introduced and results of position control are presented.
