Determining the Capability of Production Equipment

The aim of this article is the introduction of statistical control in the manufacturing process of Ribe Slovakia, k.s. (limited partnership) in Nitra, Slovak Republic, which consists of determining the capability of production equipment. The chosen production equipment is a multistage forming press SACMA SP 260, which was used in the process of cold forming when manufacturing screws of type WZ 13 340 intended for engine blocks. Determining the capability of production equipment involves removing 50 consecutive products, identification and evaluation of stability (construction of card and card), determination of normality (construction of frequency distribution series, histogram and cumulative relative frequency curve), and calculation of capability indices of production equipment Cm and Cmk.
