Análise do processo de fabricação em uma indústria metal mecânica: um enfoque através do uso de ferramentas do controle estatístico do processo.

Abstract

The aim of this work was to evolute the stability of process in metal mechanic factories localized in Campina Grande in Paraíba through the use of tools statistics’ control of process. Were reviewed concept and theory about this theme to will do theoric support to confirm, analysis and sujections of improvement. This research were to doing in line of mounting of lock F-10 just fact of this process have been the one this principal products of the factories. The studies has been based in research descriptive and exploratory and the tools used were the paper of verificaded, Pareto Diagram, cause e effects diagram, FMEA, FTA, histograms and control graphics to collect, presentation and analysis of element. About the collect saw the percentage of damaged and left studied the cause it been conduce this effects. After that, does one analysis of stability of process using controls chart tools. Than observed the level of stability about the process be out of control, or instable identified the principals causes like rework, spots forehead, bad setting of chassi, bad position latch, forehead striped, change of secret, feeble solder, bubble of forehead, and others happened in process. With this defects, will suggested more incentive to workman participation’s, the control the products make before to process, and the education based in quality to the workman diminishing the process variation and do more stability to process.
