INDUSTRIAL VISIT TO L&T MADH

INDUSTRIAL VISIT REPORT

As part of our curriculum for Manufacturing Processes, we visited Larsen & Toubro Training Center situated in Madh. We were supposed to get hands on experience on the machineries and get all the skills inducted required to complete a work-piece. Larsen and Toubro is one of the leading companies in the corporate sector and has entered in various ventures, being among the leading companies. It was a proud feeling to be visiting this good a company!

We started our session with the presentation on Safety Guidelines and General Awareness by Mr. Patil who held a masters’ degree in Safety Issue and was associated with the company for more than 30 years. He mentioned that although we can rectify the mistakes through common sense but for an accident to occur all it takes is one second. He explained to us the different ways in ways in which the mishap can take place and how we can take precautionary measures to prevent the accident, thus safeguarding the laborers’ life. Mr. Patil also went into detail of the responsibility of the management to make the workshops a workable place and how it is labors right to ask for the safety equipments if he thinks that there could be a chance of an accident. It is company’s duty to register the accident to Directorate of Industrial Safety and Health, showing the cause and how the company looks forward to prevent it the coming future.

After about a 3 hours lecture we moved to the first aid techniques, Sir showed us how to disconnect a labor from the direct shock and dos and don’ts while taking care of the self too. And also how to perform CPR on a person who has just got severe electrical shock. At the end, we got to handle the fire-extinguisher and put off the fire. We came to the end of this session with a safety anthem, promising to be a responsible engineer.

During the second half, we attended the machining workshop, which was the main aspect of the visit. The person in charge there described to us the various parts of the Universal Milling Machine, but safety first, asked us to put on safety goggles. He showed us how a spindle wheel works, how to change gears, how to set depth by adjusting the cross feed handle, also reading the lengths with every turn of the wheel. Then, we were provided with a metal slab and asked us to take the measurements of it. Next, he gave us new dimensions and by milling operations asked to reduce it to the given measurements. It was a challenging to operate the machine for the first time but in the end we managed easily.

When a job is finished, it is necessary to smoothen the surface in order to minimize the surface to surface friction. It is done by the Grinding Machine. The Grinding Abrasive Wheel, part which brushes with the metal surface to smoothen it, is made up of Aluminum Oxide and has to be polished itself to get the uniform grind. The Metal slab is kept on Table lock, which is an electromagnetic surface, and with the proper dimension, the wheel is just made to touch the metal surface, the machine flattens the surface with the reciprocating translating motion on the metal surface. In the end, we were demonstrated metal heat treatment, which can be also used in the manufacture of glass. Heat treatment is used to achieve a desired result such as hardening and softening of a material.

This visit to Larsen and Toubro added great deal of experience in terms of mechanical skills and patience. Overall it was a good exposure and according to me, we managed to achieve the purpose of the visit. In one day, one could not ask for more enriching day than this. I appreciate the support shown by the staff at L&T and also thank Chavan sir for giving us the opportunity to attend this training.

Industrial Visit To Automation and Control Systems

INDUSTRIAL VISIT REPORT

The Department Of Mechatronics had organized an Industrial Visit to Automation and Control Systems, Pune on 27^th January, 2016. The Company is a developer of On-site installation automation systems as well as training institute for Automation and Instrumentation Engineers. ACS deals with PLC softwares, AC Drives and SCADA controllers along with many sub-categorized interfaces and machine languages. Automation and Control Systems uses the Automation products of Allen Bradley, Siemens, Mitsubishi and ABB Systems. They handle distinguished clients like Ashok Leyland, Fiat, Mahindra, Godrej Sara Lee, BHEL, etc. They have also been known to provide Start-up and Commissioning Assistance.

 Mr. Mangal Bilakhia gave an introduction about the functionality of ACS in the Automation Sector. He inspired us to be above average and social rather than only be technical. There was an enthusiastic discussion on ever changing and developing technology how the students should focus their interest in right way, keeping in fact that the college curriculum and the real requirement is never going to be met. Mr. Mangal stressed that the college topper was not the only one meant to succeed and that the backbenchers are the most to turn the table their way and in this competitive world it is only the survival of the fittest.  

In ACS, first we were introduced to a Six-Axis Robot Arm built by ABB controllers. A Six-Axis Movement meant it could move sideways, up-down movement, extend-withdraw action and rotate about its axis. It could almost complete any action a human can, connected through microcontrollers and based on a complete pneumatic system. The specialty of this robot arm was that once an action is completed through manual operation, the user can save the same set of coordinates in it and the arm will follow the same path unless it is reseted. Thus, reducing the breakdown time and speeding up the operation time and neglecting the human error.

Next we moved to SCADA (Supervisory Control and Data Acquisition) Systems. It is a virtual system for remote monitoring of a complete machinery by controlling through PLCs so that the machine and the user remained in contact over communication channel. The only drawback of using SCADA system was that the user cannot override the system through the network once it has malfunctioned, that’s where DCS comes into picture. DCS (Distributed Control System) is a control system for a whole process which uses a single controller at a central locations. DCS uses HMI (Human-Machine Interface) for overlooking the distributed controllers with the central controller. The differences between DCS and HMI are merged through HMI and Allen Bradley (PLC5).

Basically all types of platforms can perform the same operation but as a programmer we have to work with the user specifications and within their budget limit. For example, for a small scale industry owner working with the DCS and HMI can be a bit costly, on the other hand, for a precision related system working with only PLC can be a little tough. Sometimes we have to use a fusion of SCADA and PLC to complete a certain process because of the different controllers compatibility.

As an application of these system, they had a small scale RO filtering and bottle filling module, which indicated where each of the sensors were used in order to bring the bottle right below the filler and the sensor to prevent bottles from getting spilled, before putting on the cap. Will there be any error? (Asked some students) No, because it is an automated machine.

Overall, an Industrial Visit was an enriching experience, there was a lot learnt and yet a lot to learn. I would like to thank our Prof. Vinod Jain, the Head of Department for providing us the opportunity to expose us to industry at this early stage. And we will be looking forward to many such visits in the coming future.

Statement Of Purpose

The Statement Of Purpose

“I Will Win, May not be Immediately but Definitely”

The sole purpose of my life is to educate myself to the highest level and have an attitude of perfection in everything I do. The process of education should not be only for the degree but to learn the basic fundamentals and be able to apply it in the practical field. Having an attitude of perfection should not mean that you are the greatest but a humble approach towards even the smallest creature on the earth. I should neither hesitate to walk with the Kings nor lose the common touch.

Marks do not matter always but that should not refrain me from the life opportunities so I ought to keep a healthy profile for myself. I should not look down on the students weak in studies and should help them to bring them up. In my lifetime, I should be generous enough to be able to finance a needy child’s education and make him independent like me.

After the graduation, I should not have to ask for any kind of help to my parents, either financial or moral, and be able to stand on my feet and complete the further studies as planned.

 While looking for a job, I have to keep a self-esteem for having a better education than the most of the counter parts, and if the job demands a various adjustment, should be ready to handle the projects imposed on me. I should be able to adjust to the job requirements till I get a good exposure but later should lay a strong foundation to work for the betterment of the company.
