COMPANY PROFILE
ROOTS INDUSTRIES LTD (RIL) is a leading manufacturer of horns in India and the
11th largest horn manufacturing company in the world, Head quartered in Coimbatore, India.
ROOTS have been a dominant player in the manufacture of Horns, Casting products,
Industrial cleaning machines, Precision products and other products like Electronic Horns,
ROOTS have its strong desire in producing world quality products compete in the
global market. It has assigned a lot of R&D activities to deliver high quality and innovative
products satisfying the needs of its customers. To make it true, ROOTS has been involved in
various activities like 5S, KAIZEN, ISO, etc. And to add a few to its milestone TPM activity
has been started in ROOTS since 2005. The divisions of ROOTS experimenting TPM are
RPCL, RMCL, ROOTS Component Division and ROOTS Horn Division. Now the ROOTS
Industries are at KICK-OFF stage in implementing TPM.
This project involves in the implementation of TPM in Model machine – PRESS
MASTER PSPR20. Primarily 5s is the base and we found problems cannot be clearly seen
when the work place is unorganized. Cleaning and organizing the workplace helps to uncover
1
problems and making problems visible is the first step of improvement. Next we have to be
involved in TPM in analyzing the machine, rectifying the sources of contamination,
abnormalities in equipments, their counter measures, fixing Tentative Standard. Our main
goal is to increase the OEE which would increase productivity, Reduce maintenance cost,
Improve reliability and maintainability, eliminating the defects at source through active
employee participation.

TPM MODEL MACHINE
The machine PSPR 20 is a pressing machine 30 ton capacity used upto 400 strokes
per minute. This machine comprises of auxiliaries such as decoiler, straightner and scrap
cutter. The machine is powered by an electric motor and operates with the assistance of
pneumatic devices, centralized electrical control system. Machine is a self lubricating at an
interval of one working hour. Decoiler decoils the sheet metal strip wounded as a coil and the
straightner straightens the sheet metal strip by the use of consecutive rollers. The decoiler and
straightner are controlled by using cam limit switches. The feeder unit feeds the sheet metal
at every stroke and actuated by pneumatics. Scrap cutter cuts the out coming strip from the
3
press for easy handling. The various process involved are piercing and blanking. The
machine consists of gauges and meters for monitoring.
This machine is used for making the Diaphragm plates, front cover plates and back
cover plates by pressing. The sheet metal coil of required dimensions is fed through the
interchangeable dies of this machine. This machine produces from 1to 5 plates according to
the thickness required per stroke.

TAG CLASSIFICATION
OVERALL EQUIPMENT EFFECTIVENESS (OEE)
OEE = Availability x Performance Efficiency x Rate of Quality product
OEE is just a number for relative comparison of equipment performance. The
real benefits come from using the factors of OEE, which lead to root cause analysis and
eliminating the causes of poor performance. It’s all about collecting, trending,
Performance Efficiency is given by
Performance efficiency =Rate efficiency x Speed efficiency.

Rate efficiency (RE): Actual average cycle time is slower than design cycle time
because of jams, minor recorded stoppages, small problems and adjustment losses etc. Hence
output is reduced due to this.
Speed (rate) efficiency (SE): Actual cycle time is slower than design cycle time because
of high vibration etc. and hence output of the machine is reduced.
Rate of quality products (yield): It is the percentage of good parts out of total produced.
OVERALL EQUIPMENT EFFECTIVENESS (OEE) MODEL CACLULATION
OEE = A x PE x Q
PE=QUANTITY PRODUCED/ (SPM * PRODUCTION TIME)
A= (TOTAL AVAILABLE TIME - NON VALID TIME)/ TOTAL AVAILABLE TIME
