Redução do custo setorial com o inserto Somx 084005 um MC 5020 utilizado na usinagem do furo da caixa satélite de um diferencial: um estudo de caso

Abstract

n the current scenario of national and international industries, there is a need for innovation aiming at aspects such as continuous growth, entry into different markets, and adaptation to the current needs of society. The use of quality tools is imperative in this scenario to ensure competitiveness and achieve short and long-term success, in addition to other advantages derived from the tools such as: technological development, cost reduction, market demands, global competition, and sustainability. For this case study in a metallurgical industry, quality tools were used to identify areas for improvement in the process and make decisions to reduce the breakage of inserts used in the calibration of a differential satellite box used in the GM Onix. This study has a methodology that involves mapping the entire production line and, through the analysis of PQCDS indicators - Production, Quality, Cost, Delivery, and Health - along with quality tools such as GUT, Pareto, Ishikawa, 6M'S, and brainstorming to analyze situations and data, make decisions. Through these MASP tools, the root cause of the problem was detected, solutions were proposed and put into practice, and thus success was achieved in reducing insert breakage. Through the implemented improvement, all other CNC lathes in the factory will be able to use the same methodology to identify the problem in advance and act accordingly. The method to identify and correct the problem can be carried out by employees of the organization in their routine activities without the need for investments; thus, the work performed was considered low-cost, in addition to the economy generated by the reduction in monthly acquisition of inserts.
