Aplicação dos conceitos de cadeia de tolerâncias em manufatura de bombas de compressores herméticos

Abstract

The competitiveness of industries is related in a circle involving quality, costs and production. Improvements in quality are aimed at improvements in mechanical design, which in turn must be manufactured at minimal cost. Chain of tolerances are applied in mechanical designs and consider probability distribution curves to size the best way to conduct the fabrication of each item involved in these chains. The "worst case" and "statistical method" methods are the most widely used for manufacturing large-scale components and aim at reducing manufacturing costs. It is with this intention that this work has its objective, which, to present a systematics to dimension a chain of dimension in the manufacture of hermetic compressors pumps in large scale.
