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

Autonomous Maintenance (Jishu Hozen) is one of the most important building blocks in any Total Productive Maintenance (TPM) program. Autonomous Maintenance refers to TPM activities that involve operators in maintaining their own equipment, independent of the maintenance department.
One of the basic principles of TPM is that operators are the first line of defense against unplanned equipment downtime. Operators and others in daily contact with equipment can use their knowledge and familiarity with operating conditions to predict and prevent breakdowns and other equipment-related losses. They do this through regular cleaning and inspection of equipment, and through team-based autonomous. maintenance activities that tackle equipment-related problems.
Activities in an Autonomous Maintenance program include: daily inspections, lubrication, parts replacement, simple repairs, abnormality detection and precision checks.
The goals of the Autonomous Maintenance program are to prevent equipment deterioration, restore equipment to its ideal state, and establish basic conditions needed to keep equipment well maintained.
Developed by our JIPM-certified TPM instructor, this Autonomous Maintenance (Jishu Hozen) PPT presentation is packed with diagrams, examples and practical tips and can be used to train shopfloor staff participating in autonomous maintenance activities.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

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

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

• 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 !!

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.
