CONTRIBUTION OF LEAN MANUFACTURING CONCEPTS TO REDUCING WASTE IN DESTRUCTIVE TESTING

Abstract

This article aims to analyze the levels of waste of components used in destructive testing for releasing the assembly line of an automotive parts factory. In this way, it aims to apply an improvement that involves the reduction of the amount of parts destroyed daily, consequently reducing their monthly costs. For this, based on the case study methodology, the percentages of discard in relation to sales of all parts currently produced were surveyed, in order to identify the line that has more discarded components and, from this, to analyze the waste factors, based on the Lean Manufacturing concepts. After the waste analysis and the application of process improvement, there was a reduction in the cost of parts for destruction. The cost, which was 0.71% of the total monthly sales, became 0.19%.
