What is Total Productive Maintenance? • TPM is a plant improvement methodology which enables continuous and rapid improvement of the manufacturing process through use of employee involvement, employee empowerment, and closed-loop measurement of results

Breakdown of TPM • TOTAL = All encompassing by maintenance and production individuals working

Breakdown of TPM • TOTAL = All encompassing by maintenance and production individuals working together • PRODUCTIVE = Production goods and services that meet or exceed customers’ expectations • MAINTENANCE = Keeping equipment and plant in as good as or better than the original conditions at all times

TPM - History • Productive maintenance (PM) originated in the U. S. in late

TPM - History • Productive maintenance (PM) originated in the U. S. in late 1940’s & early 1950’s • Japanese companies modified and enhanced it to fit the Japanese industrial environment • The first use the term TPM was in 1961 by Nippondenso, a Japanese auto components manufacturer • Seiichi Nakajima – head of JIPM, one of the earliest proponents, known as the Father of TPM

TPM - Evolution • • Breakdown maintenance Preventive maintenance (PM) Productive maintenance Total productive

TPM - Evolution • • Breakdown maintenance Preventive maintenance (PM) Productive maintenance Total productive maintenance

Goals of TPM 1. Aims at getting the most effective use of equipment 2.

Goals of TPM 1. Aims at getting the most effective use of equipment 2. Builds a comprehensive PM system 3. Brings together people from all departments concerned with equipment 4. Requires the support and cooperation of everyone from top managers down 5. Promotes and implements PM activities based on autonomous small group activities. 6. Maintaining Equipment for life 7. Encouraging input from all employees 8. Using teams for continuous improvement

Three Principles of Prevention • Maintenance of normal conditions • Early discovery of abnormalities

Kick off TPM

Launching TPM- Preparatory Stage • Announce top management’s decision to introduce TPM • Launch

Launching TPM- Preparatory Stage • Announce top management’s decision to introduce TPM • Launch an educational campaign to introduce TPM • Create an organizational structure to promote TPM • Establish basic policies • Form a master plan for implementing TPM

Launching TPM- Preliminary Implementation

What is OEE • OEE (overall equipment efficiency) is a “best practices” way to monitor and improve the efficiency of your manufacturing processes – machines – manufacturing cells – assembly lines

OEE Factors • Plant Operating Time • Planned production time – planned downtime ie.

OEE Factors • Plant Operating Time • Planned production time – planned downtime ie. breaks • Availability – downtime losses • Performance – Speed losses • Quality – Quality losses

World Class OEE

World Class OEE

Calculating OEE • Availability = Operating time/planned production • Performance = Ideal Cycle Time

Calculating OEE • Availability = Operating time/planned production • Performance = Ideal Cycle Time / Total Pieces or (total pieces / Operating time)/Ideal Run time • Quality = Good Pieces / Total Pieces • OEE = Availability X Performance X Quality

Example OEE Calculation

Example OEE Calculation

Availability = Operating time Planned production time • = 373 minutes / 420 minutes

Availability = Operating time Planned production time • = 373 minutes / 420 minutes • = 0. 8881 (88. 81%)

Performance = (Total pieces /Operating time) Ideal Run Time • = (19, 271 pieces/373

Performance = (Total pieces /Operating time) Ideal Run Time • = (19, 271 pieces/373 minutes)/60 pieces per minute • = 0. 8611 (86. 11%)

Quality = Good Pieces Total Pieces • = 18, 848 / 19, 271 pieces

Quality = Good Pieces Total Pieces • = 18, 848 / 19, 271 pieces • = 0. 9780 (97. 80 %)

OEE = Availability X Performance X Quality • = 0. 8881 X 0. 8611

OEE = Availability X Performance X Quality • = 0. 8881 X 0. 8611 X 0. 9780 • = 0. 7479 (74. 79%)

TPM BENIFITS

TPM BENIFITS

TPM - Benefits • Improved equipment eliminates the root cause of defects • Defects

TPM - Benefits • Improved equipment eliminates the root cause of defects • Defects are prevented through planned maintenance • Preventive maintenance costs are reduced as equipment operators conduct autonomous maintenance • Improved equipment designs ensure that new equipment naturally produces fewer defects • Simplified products designs and a redesigned process produce with few defects • Engineers, technicians and managers are trained in maintenance and quality

TPM - Benefits (Japanese TPM Prize winners during 19821984) • Equipment failures reduced from

TPM - Benefits (Japanese TPM Prize winners during 19821984) • Equipment failures reduced from 1, 000/month to 20/month • Quality defects reduced from 1. 0% to 0. 1% • Warranty claims reduced by 25% • Maintenance costs reduced by 30% • WIP decreased by 50% • Productivity improved by 50%. (Patterson & Fredendall, 1995)
