Role Of Planned Maintenance InImplementation Of TPM


3/58


What is TPM?

Total Profit Management

Company Survives

Total Production Management

ISO, TQM, JIT, Re-Engineering

Total Perfect Manufacturing

. Loss Elimination

Total Productive Maintenance and Management


4/58


By implementing TPM, we get a proper image of

manufacturing product in the age of automation and

microelectronics, there by contributing to the

prosperity of enterprises and the happiness of

mankind.

TPM Principles


5/58


Through TPM

1. We pursue efficient production systems and accomplish the highest

customer satisfaction for quality, cost and delivery term.

2. We accomplish zero-disasters & accidents, zero-defects, and zero

breakdowns to build safe and cheerful workshops.

3. We accomplish zero-disasters and zero-pollution to make life safer and

more pleasant, not only for employees, but also for local residents.

4. We eliminate all losses in the resources and energy to conserve the Earths

environment.


6/58


CHANGE THE MACHINE.

CHANGE THE MAN.

Basic Concept Of TPM


7/58


Obtain Minimum 90% OEE( Overall Equipment Effectiveness )

By Keeping Target For All Losses - ZERO

Operate in a manner, so that there areno customer complaints.

By Keeping Target of Defects - ZERO

TPM Targets


8/58


TPM Targets

Reduce the manufacturing cost

By Keeping target of Losses - ZERO

Achieve 100% success in delivering the goodsas required by the customer.

By Targeting Losses -ZERO


9/58


TPM Targets

Maintain a accident free environment.

Target For Accidents - ZERO

Increase the suggestions by 3 times. DevelopMulti-skilled and flexible workers.

ZERO MEANS ONLY ZERO !!!

ZERO HAS NO TOLERANCE

ZERO DEFECT

ZERO BREAKDOWN

ZERO ACCIDENT

What Is Zero.


12/58


Just Imagine that if 1% of all the flights crashed.

Just Imagine that if 1% of all the heart surgeries

failed.

Just Imagine that if 1% of the buildings collapsedsoon after construction.

Importance Of Zero.

Planned Maintenance

Aim : Enhance maintenance efficiency through

1. Accomplishing zero failures and zero defects byactivities to enhance maintenance technology andskills, to expand equipment MTBF and to shortenequipment MTTR.

2. Reducing input by activities to make equipment

maintenance efficient.

Purpose :

Functions of equipment can be

demonstrated satisfactorilywhenever equipment needs them at minimumcost.

Basic Philosophy of Zero Failure

Men make equipment fail.

Equipment can be set for zero-failures provided the thinking

of men change.

Conventional view of all equipment can fail should be

changed to dont let equipment fail.failures can be reduced to zero.


29/58


Rules for Zero Failure

Discover latent defects to prevent failures.

Failure

Dust, Soiling, adhesion of rawmaterials.

Abrasion, backlash, looseness, leaks

Corrosion, deformation, flaws, cracks Temperature, vibration, sound and other

errors

Failure is only the tip of the iceberg.
