The dependences analysis between the non-conformities level (PN) and downtime (TP), breakdown time (TA), coefficient of operation (WE), coefficient of speed (WPD), coefficient of useful operating time (UCD) and coefficient of utilization (WW) are shown in Table 4.
On the basis of machine working time, taking into account failures and other outages, the analysis for TPM coefficients was calculated: coefficient of operation (WE), coefficient of the speed (WPD), coefficient of utilization (WW) and coefficient of useful operating time (UCD), calculated according to formulas (1), (2), (3), and (4) (Borkowski and Selejdak 2007; Jostes and Helms 1994).
The impacts of individual factors of TPM: breakdown time (TA), downtime (TP), coefficient of operation (WE), coefficient of utilization (WW), the coefficient of speed (WPD), the useful operating time, time of accident forms (TAF) and the time machine failure (TAM) on the level of quality (BS represented as the level of non-conformity) are presented in the form of the correlation graph (Fig. 3).
The analysis of Fig. 3 shows that for both analyzed machines there are: significant positive correlations between the downtime (TP), breakdown time (TA), forms breakdown (TAF) and the non-conformity level (PN), significant negative correlation between the coefficient of operation (WE), coefficient of speed (DPN), coefficient of utilization (WW) and the level of castings non-conformities (PN).
