Achieved cost optimization, time reduction using Lean Manufacturing techniques and improved Material estimation by efficient Layout preparation.

Performed quality validation, product review, validation of parts and preparation of Bill of Materials (BOM).

Improved and modified manufacturing and production techniques using FMEA which resulted in better quality with increased cost competency in the market.

Summer Intern, Group Lead, Hindustan Aeronautics Limited (H.A.L), Bangalore, India July’11

Worked on the manufacturing of various aircraft components using CNC technology and machinery.

Carried out a detailed survey on various production techniques employed in all departments of the Aircraft Division and an organized report was presented.

Industrial training regarding Aircraft components, Structure and controls, Foundry and Forge, Plastic shop, Heat treatment and various other departments.

RESEARCH EXPERIENCE

Research Intern (Nano-technology), Dept. of Materials Science and Engineering, Wright State University May’14-Aug’14

Developed a water purification system using nanomaterials to better the quality of purified water.

Conducted water flow experiments using carbon foam and carbon fabric.

Silver deposition was carried out using new modified techniques and the water flow rate through it was calculated.

SEM and Micro-analysis was conducted to check for uniformity in deposition techniques employed and results were found to be quite satisfactory.

ACADEMIC PROJECTS

Department of Materials Science and Engineering, Wright State University Mar ’14 – Apr ’14

Failure Analysis of a Torsion Spring in a Garage Door

Failed sample was cut, treated, mounted, polished and investigated.

SEM and optical microscopic examinations were conducted to determine the kind of failure and to identify the material of the specimen.

Cause of failure was detected and a report was prepared and presented.

Department of Mechanical Engineering, Visvesvaraya Technological University Sep ’11 – June ’12

Velocity profiling and analysis of aerodynamic bluff bodies using a self-fabricated low turbulent wind tunnel, adopting flow visualization technique

A Prototype wind tunnel was designed using CATIA V5 and fabricated with sheet metal.

Projection manometer was used to measure and profile the velocity variations inside the wind tunnel.

Flow visualization technique was used to study the actual air flow around the geometry of the bluff body.

Pictures were taken using a digital camera and results were compared with theoretical data.

Department of Mechanical Engineering, Visvesvaraya Technological University Jan ’11 – June ’11

Polymer Composites

Manufacturing of the hybrid polymer was done by Hand lay up process.

The epoxy– hardener mixture resin was used between adjacent layers to bind the layers of carbon and glass fibers alternatively, with the carbon fibers used as a surface layer.

Manufactured composites were cut along different orientations according to ASTM standards.

The specimens were tested in a UTM using different fixtures and the Tensile and Flexural Strength of each specimen was tabulated.
