Implementation of methodology for analyzing the added value in a metallurgical industry of custom products

Abstract

This paper addresses the implementation of a methodology for the analysis of added value in a job where steel sheets operations are processed by oxyfuel in a CNC (computer numerical control) machine. The method used was based on a case study, followed by descriptive research by observing and recording the movements of the work. For this purpose, all the movements and tasks of the operators and the machine were defined, and classified according to the concepts adopted by Ohno (2002). Their chrono-analyses occurred in the period from March to June 2010 and later improvements were made throughout the workplace, allowing the elimination and reduction of losses, significant increase in the added value and increased occupation of the machine. Through this case study, it was found that the understandings of Ohno (2002) about the added value developed for an automotive industry manufacturing a standard product are perfectly applicable to a company that works with a production system under design and does not manufacture standard products
