【正文】 Maintenance Approaches Time Based or Planned Maintenance Periodically scheduled maintenance actions. Predictive Maintenance Maintenance action performed resulting from evaluation of equipment condition. Corrective Maintenance Maintenance action performed to restore optimal equipment function. Preventive Maintenance A bination of Time based and Predictive Maintenance and actions taken to sustain optimal equipment performance and preclude breakdowns. 14 Early Equipment Management Optimizes equipment selection through: ? Equipment Life Cycle Cost Analysis : analysis of the sum of all costs (direct and indirect) associated with an item of equipment throughout its period of use. ? MP Design: activity which is focused on minimizing future maintenance costs and production losses of equipment at the design stage. 15 Total Productive Maintenance Without TPM With TPM MED Industrial Engineering Maintenance MED Industrial Engineering Operation Maintenance The operator operates, maintenance maintains, etc. Shared responsibilities Operation 16 Equipment Maintenance Responsibilities Operation Maintenance MED Industrial Engineering Autonomous maintenance Breakdown maintenance Planned maintenance Predictive maintenance Maintenance prevention 17 Total Productive Maintenance TPM Equipment in better working condition Decrease of breakdowns Decrease of inprocess adjustments Optimization of operation speed Manufacturing defects Leadtime Quality the first time 18 Performance Excellence: Expanding the Strategy through TPM Introduction Role in Lean Manufacturing Role of the Operator in TPM Autonomous Maintenance Implementation Equipment Performance: Measurement and Management 19 Total Productive Maintenance TPM, the total approach ? The operator is the first line caretaker ? Maintenance personnel are the specialized caretakers. 20 Division of Maintenance Duties between Production and Maintenance Depending on knowledge and skills required, responsibility for equipment maintenance tasks needs to be defined: Maintenance Technician Production Operator * Equipment overhaul * Basic lubrication * Special skill tasks * General cleaning * Complex adjustments * Multipoint inspection * High safety risk tasks * Basic adjustments 21 Maintenance Task Allocation between Production and Maintenance Maintenance Technicians Production Operators Autonomous maintenance implementation Volume of maintenance tasks 22 Performance Excellence: Expanding the Strategy through TPM Introduction Role in Lean Manufacturing Role of the Operator in TPM Autonomous Maintenance Implementation Equipment Performance: Measurement and Management 23 Autonomous means “independent” Autonomous maintenance refers to activities involving operators in the maintenance of their own equipment. Autonomous Maintenance 24 Autonomous Maintenance How to make the operator more independent: ? Make the documentation available (manual, maintenance schedule, log book). ? As a team, define manufacturing/maintenance/MED productive maintenance activities. ? Show operator how to perform daily checks and take corrective actions. ? Train in basic operation, maintenance and defect detection techniques. ? Make daily activities visible ? Clearly identify items to supervise 25 Process Critical Machinery Equipment ?Map the process and identify critical equipment Turning Drilling Cutting Cleaning Stripping Painting Shipping 26 Adverse effects of inadequate cleaning 27 Adverse effects of inadequate cleaning: ? Failure equipment failure resulting from dirt and contamination affecting precision ? Product defects contamination of products or defects arising from insufficient cleaning ? Accelerated deterioration dirt and scale buildup shortening useful equi
