An application of value analysis and a study of machine shop capacity through sampling based on component characteristics and value classification

Abstract

This paper deals with improvements in manufacturing effectiveness found possible through examination of design and machining requirements for light mechanical/electrical lifting equipment, manufactured on a batch basis. Value analysis and value engineering concepts were applied to the design of a small overhead travelling trolley. The aim of the value analysis was to achieve maximum savings from modifications to the existing design, whilst that of value engineering was the development of a conceptually-new design directed towards minimum manufacturing cost. The potential changes and savings from both approaches are described. In the machine shop capacity study, components were first coded and classified by the VUOSO system and a representative sample, by value, taken as the basis for the process planning investigation. By reference to revised machining methods, standard data, and the maximum use of special tooling, jigs, fixtures and carbide tooling, a possible average reduction in machining time of appro...
