Transcript of Copy of Copy of TPM

TOOLS OF TOTAL PRODUCTIVE MAINTENANCE
Progress
Maintenance signifies methods for the determination and evaluation of the current status as well as for the preservation and reestablishment of the nominal status of facilities, machines and components.
What is the Maintenance?
Why is it so important?
reduces maintenance costs
increases process stability
extends equipment life
reduces maintenance spare parts inventory
supports Continuous Improvement
Total Productive Maintenance
One of the main objectives of TPM is to increase the productivity of plant and equipment with a modest investment in maintenance
Main targets:
Waste = 0
Defect = 0
Breakdown = 0
Accident = 0

Steps of implementing SMED
What is SMED?
`
Single-Minute Exchange of Dies is a system for dramatically reducing the time it takes to complete equipment changeovers.
The Big Idea
Changeovers can be reduced in many cases to less than 10 minutes. Each element of the changeover is analyzed to see if can be eliminated, moved, simpified or streamlined.
What is it?
How does it help?
Organize the work area.
Eliminates waste that results from a poorly organized work area (e.g. wasting time looking for a tool).
ANDON
Visual feedback system to the plant floor that indicates production status, alert when assistance is needed, and empowers operators to stop the production process.
Poka - yoke
Error proofing
Design error detection and prevention into production process with the goal to achieving zero defects.
PLAN
establish plan and expect results
DO
implement plan
CHECK
verify expected results achieved
ACT
review and assess; do it again
PDCA
An iterative methodology for implementing improvements
OEE - Overall Equipment Effectiveness
Framework for measuring productivity loss for a given manufacturing process.
Three categories of loss are tracked:
Availability (e.g. down time)
Performance (e.g. slow cycles)
Quality (e.g. rejects)
100 % OEE means perfect production (manufacturing only good parts, as fast as possible with no down time.
