Abstract
This article takes the example of a machine for manufacturing hollow shafts made of solid material (i.e., a spin extrusion machine) to outline the experience derived as well as a procedure for developing and building mechatronic drive systems in forming machines with a combination of electrical and hydraulic axes. 4 hydraulic and 3 electrical axes work in this machine's interpolating combination of axes. An iterative process of development facilitated by experiments was devised based upon an extensive description of a model theory on the interactions between the control mechanism and drive process while using a simulation to study a control design based upon the CNC 840D. This study focuses on a description of the technique, modeling the forming process with special emphasis on modeling the hydraulic drive system, forming the overall model and coming up with the baseline control strategies for the axes. This article will finish with a presentation of the relevance these procedures and statements have to future research projects in the field of mechatronic drive systems for forming machines.
