Résumé:
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.
