The stoppages are: machine breakdowns breakdowns related to tools breakdowns related to the product stoppages for changeovers (used or broken) stoppages for frequent adjustments stoppages for inspection (SPC sampling) stoppages for maintenance Stoppages for tool changeovers are not taken into account TPM BREAKDOWNS AND MICROSTOPPAGES: ? BREAKDOWNS –Stoppages = 5mins –Not often –Systematically noted –Stoppage affects the entire working group –Intervention of an expert –Research necessary before startup –Identifiable causes ? MICROSTOPPAGES –Stoppages 5mins –Often –Not noted –Little or no perception by the group –Easy startup without elimination of the cause (suppression of the effect) –Non identified causes –Little motivation to eliminate them because little perceived impact on production –Strongly involve the operators and automatic installation people for tasks without Added Value
