  • Assist in Scoping new project opportunities for future productivity opportunities
  • Studying and optimizing manufacturing processes
  • Suggesting analytics initiative to improve material tracking on the shop floor
  • Brought about $344K+ worth of saving with initiatives since late 2019.

• Led team of four in performing experimentation and analysis during project aimed at improving fuel consumption of rotary hearth furnace.

  • Generated annual savings of $233K+ by optimizing furnace’s fuel oil consumption without any cost implications; observed and pinpointed critical points in processes; compiled and analyzed experimental data, based on which recommendations were made; implemented proposed configuration.
  • Increased productivity 5% over course of a month; initially, excessive scaling occurred on heated billets when they exited furnace and entered radial forging machine; redistributed soaking time and decreased air flow in soaking area, thus reducing oxidation; achieved better forgings due to non-inclusion of scales, which resulted in fewer rejections.

   

• Wheel Shop: Studied the Manufacturing Processes of Steel Making, Pressurised Bottom Pouring technique, heat treatment of cast wheels.
• Axle Shop: Learned about the Radial Forging for manufacturing railway axles, heat treatment of axles, machining, inspection and assembling of wheel sets.
• Apart from this we also had hands on training in dis-assembly and assembly of four stroke diesel engines in the motor shop.
• Achieved the firsthand knowledge about the Pressure Pouring Technique and Radial Forging processes.

To produce a computer controlled conveyor belt that moves and positions items with sub-millimeter within two years and under a budget of $1.6M. Discussed, the scope statement, deliverables, milestones and technical requirements of the project. Developed work breakdown structure and network diagram for the activities while assigning resources, budget reserves, and management reserves to the work packages. Through each of the four phases of the project lifecycle, the quarterly status reports presented to the VP of operations identified all the conflicts in each of the quarters. Changes in cost, schedule, EVMS & Trends analysis performed highlighted the areas where the focus was of the essence. Factors were marked by the end of the fourth quarter to be on the watchlist. Recommendations were made to make sure that the project was on track and budget, if not under budget.

With the knowledge of Rail Wheel Factory (RWF) facility and production capability, quality improvement study was carried out. Following the PDCA cycle, through various total quality management techniques like the '5 Whys', Root cause analysis, flow charts, Ishikawa Diagrams  and Pareto analysis, areas where further quality improvement could be carried out were revealed. Based on the data experiments were designed and carried out to attain the optimum quality. Suggestions were made to bring about to counter the issues and improve the quality. 

Trained in the basics of facility planning. Planned and constructed a basic facility model for a firewall construction company as part of my MASTERS coursework. It demonstrated how the company would perform each function.

Trained about simulation tools and their usage in facility planning. Trained in the basics of SIMIO (software package) as part of my MASTERS coursework. Constructed a simulation model of Rail Wheel Factory (RWF) on the SIMIO software package.

Trained in the basics of human factors engineering: What are the various factors that affect the workers' performance and how they hinder the overall performance of the system. Trained about the various techniques to counter their effects on the system, as part of my MASTERS coursework.

Performed a direct time study to determine the standard time it takes an employee to make a sandwich. Performed analysis on the various foreign elements that affect the time and performance of the employees using the snapback and continuous method. Based on the result, suggested the ways to improve and counter the foreign elements.

Attended lectures and presentations conducted by renowned experts. Trained in the basics of Line follower robots and the associated programing. Assembled a Line follower robot and successfully executed the instructed commands.

Learned about the various manufacturing processes implemented for manufacturing of Etios sedans.

As a part of ISHRAE (Indian Chapter of ASHRAE) we were taken to ISRO. Learned about the assembly of various sub-systems for the space crafts namely, MOM to keep the thermal loading within the acceptable parameters. Learned about the history of the various Indian satellites.

Six Sigma Foundation Certificate

This introductory course gave me a thorough understanding of Six Sigma and how to eliminate defects through fundamental process knowledge. Undergoing this course now enables me to quantify the critical quality issues in a company and then apply statistics to provide probabilities of success and failure. In addition to DMAIC and Six Sigma philosophy, the course also provided knowledge about basic statistics, statistical process control, process capability, financial implications and cause analysis. Comparatively, this course was shorter than many other Green Belt courses because it included only the tools and information, necessary for immediate application
