【正文】 le dimensionnel axe Board or datasheet for scheduling the preventive maintenance To be done JL Observed defect finished JL Nothing wrong TPM: preventive maintenance Working conditions Property of Valeo Duplication prohibited EXAMPLES Obvious TPM ?Visual mark for Min and Max levels ?Mark to locate the stop position of a mobile part of a machine ?Red mark for pressure manometer ?Important screws with nut tightening are repaired with visual mark (see 2 on page 49) ?Grease locations are highlighted with arrows, numbered and coloured ?Part list is labelled on containers (oil tank, pump for greasing operations...) EXAMPLES Obvious TPM 1 2 3 FIELD APPLICATION TPM PILOT WORKSHOP ?CRITERIA –Line or bottleneck machines (in order to gain capacity and availability) –Presenting a low MTBF –Strongly penalising the flow –Semiautomatic installations consisting of manual workstations (the activity of the operator depends upon the good functioning of the installation) schedules ?Preliminary 5S operations ?implementation of cleaning procedure ?implementation of inspection procedure ?visual anisation ?TPM methodology ?TRS measure ?MTBF measure ?Treatment of breakdowns ?Treatment of microstoppages ? Complement the preventive maintenance procedure TPM TPM: MICROSTOPPAGES TREATMENT METHODOLOGY From the noted effect, define the diagnosis method of causes Record the microstoppages Select the micro stoppage to be treated Quantify the causes (counting) Identify the possible causes of the micro stoppage PROCESS People Concerned Methods Steering: Supervisor Execution: Operators, Supervisor, Maintenance and Manufacturing Engineering Technicians Methods: meetings on the shopfloor with problem solving tools ( Pareto Brain Storming 5M causeeffect diagram 5 Why39。ti Graissage carter Contr244。vrier Mars Avril Mai Juin Juillet Septembre Octobre Novembre D233。rification serrage vis support b226。15mn Repair time between 15 amp。vrier Mars Avril Mai Juin Juillet Septembre Octobre Novembre D233。TPM METHOD TPM GLOBAL INDICATOR: THE TRS TRS = Quality production time Opening time TRS = Number of good parts produced x Cycle time Opening time Cycle time = Initial reference + improvements Initial ref. = Minimum technical time TPM RELIABILITY INDICATOR Average of good working time MTBF = Actual production time Number of real stoppages TPM RELIABILITY INDICATOR = MTBF (mean time between failure) It is the average duration in minutes during which the machine or the installation functioned without any stoppages. 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 f
