A high resolution electro-mechanical actuator for automated skiving

Abstract

This thesis describes a step by step approach to the design, assembly and final testing of a high resolution electro-mechanical actuator which will be an integral part of an automated skiving process used in the shoe manufacturing industry. It is referred to as a skiving machine in this thesis. The thesis provides the necessary background information as to the reasons for replacing a previous machine and then investigates the features considered suitable for incorporation into the new skiving machine. An investigation is carried" out into the desired objectives of the new design and the components to be used. A discussion then follows into the most desirable design systems to be considered for the skiving machine. It is concluded that a system comprising, of- actuating pins, levers, transmission wires and,, solenoids has the most ' appropriate combination of I, characteristics for a satisfactory machine, a' detailed description of the completed design and its parameters is given in relation to the initial objectives. There follows a description of the manufacture' and assembly based upon the design principles. The thesis then describes the performance of the machine and evaluates its skiving capability. Finally, suggestions for future improvements and further integration of the automation process in shoe manufacturing are made.
