Mobility and kinematics analysis of a novel 5-DOF hybrid manipulator for reconditioning of mould and die tools: Part 1

Abstract

In this paper, the requirements for a mechanical manipulator for achieving reconditioning of mould and die tools are determined. Reconditioning of mould and die tools involves the following manufacturing processes; identification of defects, cleaning of mould/die tool, deposition of material (metal), welding of material (TIG/laser), rough machining and finishing to specs, polishing and heat treatment, in sequential order. Current technology trends in the reconditioning of mould and dies is presented. The different defects that occur in mould and die tools that can be repaired such as wear, craters, chipping, etc are presented. Using the knowledge of the different manufacturing process and defects that occur in mould and die tools, specifications of a mechanical manipulator for reconditioning of mold and dies are determined. Finally, suitability of 5-axis milling machine technology for re-conditioning of mould and die tools is evaluated. This is done by presenting current 5-axis milling technology.
