Abstract

This article deals with the statistics pursing the process capability of turning in screws production in RIBE Slovakia, k.s. In technical prac-tice, an important group of statistic methods is formed by analyzing qualification of measures, production equipment and qualification of process. By the term “process qualification“ we mean the ability of the process to observe required technical parameters by required value and tolerance limits. Findings of the process capability can be isolated in the estimate process capability (before starting the production) and permanent process capability. Also, we have finished the quest for the process capability where the indexes Cp and Cpk are bigger than the determined value of 1.33 points.
