We are facing Below mentioned issue on M- 1& M-3 Lines since from long time
1) The Mussing PLC goes in holt mode at the time of starting the cell.
It will take few minutes to restart after repeatedly switching on – off. at the beginning of shift
This problem is savior at two places waz . Down tube and Steering Head. ( M-1 Line)
It is risky from maintenance point of view & there are chances of damaging the PLC permanently
As the Messung has windup their business spares parts management is also a headache for us .
As per discussion with my team members and consequently with you in present scenario we have to replace the Messung PLC by Mitsubishi PLC ( like Installed on M-2 Line) is the only alternative.
I am preparing the action plan for same with my team.
But we need your valuable technical support in this case.
Once the management approves budget and according to production planning we can work out for micro level plan.
Waiting for your support and guidelines. JH ACTIVITES
2. Total Productive Maintenance
• Total
Total participation - everybody is involved
Total machine
Total life cost of ownership
Total effectiveness
• Productive
Optimal equipment conditions for Production
Optimal maintenance-process Performance
• Maintenance
Maintenance Prevention
Improved Maintainability
Preventative Maintenance
Moving from the old attitude “I operate it and you fix it!” to the new attitude “We are all responsible
for our equipment!”
5. The 3 Principles of TPM...
1) Detection: Using preventive and predictive technologies to
inspect, detect and then correct small defects before they can
become costly repairs
2) Restoration: Restoring equipment to optimal conditions
3) Prevention: Preventing small defects from becoming major
problems by correcting them before they become costly
repairs
6.
7. Types of Maintenance
Maintenance Prevention - designing or selecting equipment that will run with minimal maintenance and is
easy to service when necessary.
Predictive Maintenance - determining the life expectancy of components in order to replace them at the
optimum time.
Autonomous Maintenance - involving production employees in the total machine maintenance process.
Goes with 5S well.
Preventive Maintenance - using schedules or planned maintenance to ensure the continuous, smooth
operation of equipment.
Systematical Preventive Maintenance : tasks to be systematically performed on schedule
Conditional Preventive Maintenance : tasks to be performed or not after scheduled checking
Corrective/Reactive Maintenance - Fixing an existing equipment when it breaks or looses its original
performance

11. Autonomous Management
• Definition : Direct participation of production operators in the
management of the machine through daily check, lubrication, early
detection of abnormalities, replacement of parts or small repair.
• Is the system to re-educate ourselves whilst restoring and improving
our machines :
• Developing our people and enabling them to take care of their
machines
• Influencing of the personal attitudes, value and behaviors of our
employee to continually enhance the condition in which they
work
• Creating the base and the resource for performance improvement
Through AM We change our people and machines !!
12. Autonomous Management : Definition
12
SHARED RESPONSIBILITY OF MAINTAINING ”BASIC CONDITIONS” OF
EQUIPMENT BETWEEN PRODUCTION AND MAINTENANCE
Daily/Time-Based Maintenance
– Cleaning
– Lubrication
– Tightening
Daily inspection by using 5 SENSES
Right operation, right adjustment, right setting
“I operate, You fix.” “We are AlI responsible for
Our equipment.”
“I operate, You Clean.” “We are AlI responsible for
cleanliness of Our line.”

20. The Five S
The Five Steps of Housekeeping
1. Sort: Separate out all that is unnecessary and eliminate it.
2. Store: Put essential things in order so they can be easily accessed.
Everything has a place… and is in its place. And visual
management.
3. Shine: Clean everything – tools and workplaces – removing stains,
spots, debris and eradicating sources of dirt. Bring everything to
“NEW” and better than new.
4. Standardize: Standardize the previous three steps to make the
process one that never ends and can be improved upon.
5. Sustain: Make cleaning and checking routine.

1. Initial Cleaning
(Initial Inspection &
“Restoration”)
2. Source of Contamination
& Hard-to-Reach areas
3. Standards of Cleaning
& Lubrication
4. General Inspection
5. Autonomous Inspection
6. Standardize Autonomous
Maintenance operations
7. Autonomous
Management
-Detect problems of lines and restore its original state.
-Start managing the line autonomously.
( 5S, Minor Stops, Quality )
-Create & perform temporary
“Cleaning/Lubrication procedures.”
-Solve “Sources of Contamination” and
“Hard to Reach” areas. (Cleaning, Inspection, Lubrication)
-Develop tentative standards for cleaning, lubrication and
inspection.
-Provide training on their equipments, products and
materials, inspection skills and other AM skills.
Develop a routine maintenance standard by operators
Standardize routine operations related to workplace
management such as quality inspection of products,
life cycle of jigs, tools, set up operation and safety.

• Initial Cleaning is not an one time event. It should be repeated monthly.
• The more restoration you continue, the less Initial Cleaning time you will
need.
