PROFESSIONAL EXPERIENCE

Process Development Engineer, Smith International, Utah

(Oct 2007 - till date)

20000 employee Fortune 500 Oil Service Industry

. 70% of daily activities devoted towards driving lean

manufacturing initiatives, addressing daily production issues, root

cause analysis and implementing process improvements.

. Worked on various projects with cross functional teams involving

manufacturing, quality, and product engineers to identify the root

cause and implement corrective actions

. Conducted an FMEA study on process scrap and rework issues for an

operation in Pressed Capsule cell.

. Developed, implemented and trained personnel on First article

inspections and job set-up quality checks which decreased process

scrap and rework by 30%.

. Optimized capsule design to improve surface flatness of the pressed

product. Efforts resulted in reducing manufacturing lead time by

25%, increased first-time through yield and increased labor

utilization.

. Implemented Visual Work Instructions (VWI), operator and quality

auditor process flow with work instructions.

. Conducting a project to transform batch process in Pressed Capsule

cell to continuous flow. Project is targeting to reduce manufacturing

lead time by 60%, reducing WIP inventory by 40%, streamlining process

flow and increasing direct labor efficiency

. Implemented a part scanning system in X-ray Fluorescence (XRF)

scanning of as-pressed product to detect product specification

variations. This system has poke-yoked product rejection, resulting in

reducing consumer bias thereby reducing scrap

. Liaison between Product Development and Production groups for new

product implementations.

. Designed a technique to measure the cold cell pressure of High

pressure and High temperature (HPHT) presses using resistive gages.

. Applied Finite element concepts to improve uniform heating of the

products pressed on HPHT presses.

. Applied problem solving techniques such as Kepner Tregoe to solve

manufacturing problems.

Metallurgist, California Pellet Mill, Crawfordsville, Indiana

(Jul 2006 - Sept 2007)

50 employees, World leading equipment supplier for Food Processing Industry

. Performed root cause and failure analysis for different grades of

steel.

. Developed heat treatment procedure for different grades of steels used

in pelletizing industry.

. Quality inspection of the finished products.

Graduate Research Assistant, Wright State University, Dayton, Ohio

(Aug 2003- Jun 2006)

. Synthesis & Characterization of High Temperature Superconductors:

o Used Design of Experiments concepts to develop superconducting

ceramic thin film using colloidal dispersion of ceramic oxide

nanoparticles for electronic industry applications

o Optimized processing parameters of nanoparticle superconducting

thin films to improve the properties, like microstructure, critical

temperature (Tc), and critical current (Ic).

o Characterized the ceramic thin films. Surface morphology was

studied using SEM and Optical Microscopy, surface texturing using

XRD, chemistry using XPS and four point method was used to measure

electrical properties.

. Development and Failure Analysis of Polymer Composites for Advanced

Applications:

o Investigated the influence of thin films on surface chemistry and

related physical and mechanical properties of carbon foam

reinforced polymer matrix composites using XPS, SEM and stress Vs

strain measurements.

o Investigated the effectiveness of surface functionalization of

reinforcement on interfacial adhesion and mechanical properties of

nano-fiber reinforced polymer matrix composite using compression

test

Research Intern, WIDIA (INDIA) Limited, Hyderabad, India

(Nov 2000 - May 2001)

. Powder processing of tungsten carbide and cobalt composite with

variable compositions used in machining tools

. Performed detailed microstructural and mechanical characterization on

the processed composites

. Optimized the process variables (composition, pressure, sintering

temperature) for the desired properties of composites
