【正文】 ne Breakdown – Tool Breakdown – Part Failure ? Meantime to Repair (Goal is to minimize) – Diagnose problem – Correct problem – Set up Machine to make good parts – Spare parts control ? Analyze using Statistical Tools – Reliability Measures – Problem Solving Tools – Vibration Analysis Tools TPM Reliability Kaizen Examples 1) Tool cutting Tip (Nissan Motors) Life Cycle = 45 pieces KAIZEN 1 – Vibrational analysis to optimize rotational speed. Life cycle = 132 pieces. KAIZEN 2 – Analysis of wear pattern to optimize tool geometry. Life cycle = 305 pieces. 2) Tool cutting (Toyota Motors) Tool expensive and takes long time to set up KAIZEN 1 – Reduced setup time from 15 minutes to less than 10 seconds. KAIZEN 2 – Studied correlation between life of tool and number of cuts between sharpening – increase life of tool fivefold. Planned Maintenance Best Practices ? Maintenance department primarily responsible ? Readjustment of Machines to bring back to original state ? Feedback information to Maintenance Prevention Group ? Collection of Reliability Data – MTBF – MTTR – Finding and coping with chronic defects – Machine accuracy control (calibration) – Schedule boards (Visual Management) – Control of ? Spare Parts ? Lubrication ? Vibrational Analysis Maintenance Prevention Best Practices ? New equipment design integrated w/ New Product Introduction (NPI) efforts ? Input from Reliability Maintenance ? Input from Preventative Maintenance ? Input from KAIZEN activities ? Life Cycle Costing ? Design reviews (Operators, Supervisors, Engineers) ? Assembly at Supplier ? Final Inspection at Supplier ? Maintenance and Operations Manual preparation ? Safety Issues visible, aware and worked ? Preventative Maintenance Schedule posted, adhered to TPM – Summary ? Total Productive Maintenance is about: – improved equipment performance – increased equipment availability – increased equipment FPY (first pass yield) or also called FTT (first time through) – reduced emergency downtime – increased return on investment – increased employee skill levels – increased employee empowerment TPM – Breakout Activity With a small group, With regard to Maintenance Decide at least 3 new improvements to p
