PROFESSIONAL EXPERIENCE

3M PRECISION OPTICS / US PRECISION LENS, INC., Cincinnati, Ohio 1992-

2008

Advanced Manufacturing Engineer 2002-2008

Provided technical support for the Prototype and Mold Engineering

Department in the development of prototypes and provided support for

Operations Department to transition new processes to production.

( Used statistical methods to develop capable low birefringence

processes for the molding of prisms which resulted in the first hand held

mobile projector going to market.

. Conducted simulations using C-Mold or Mold Flow it identify potential

molding issues and establish initial process parameters for the molding

of prototypes prior to mold fabrication.

. Conducted safety audits for several departments and issued corrective

actions when needed.

. Developed capable process for multi-cavity molds producing 110 mm

diameter optics with a tolerance of 0.6 microns.

. Converted six cavity molds to hot runner molds with a savings due to

scrap reduction of approximately $400,000 / yr.

. Coordinated and prioritized the workload of direct reports (consisting of

2 Engineering Injection Mold Machine Setups, a senior process engineer, a

mold designer, an Engineering Technician and a Metrology Technician) to

ensure milestone and schedules were met in the development of new

product. Conducted reviews and career development plans for each direct

report.

. Trained 3M China molding engineers in the aspects and best practices of

low birefringence optical molding in order to successfully transfer the

molding capabilities from the US facility to 3M Suzhou.

( Provided process-engineering input during Mold Design Reviews to

ensure the best mold design for prototype and multi-cavity production

molds.

Video Optics Molding Engineer 1996-2002

Developed robust processes for the molding of large optical elements and

trained production mold technicians on any new technology implemented with

the new processes.

. Certified that injection-molding machines required capabilities were

achieved and documented prior to shipment from supplier.

. Established processes for eight cavity optical molds ensuring cavity to

cavity variation less than 18 microns. Optical elements were

approximately 75 mm in diameter.

. Trained mold technicians on the theory and operations of injection

compression molding.

( Ensured all department procedures and training were documented in

accordance with ISO 9001 standards and maintained library of injection

molding processes for all products.

. Assessed engineering department's metrology needs/capabilities and

advised management on any need for additional personnel or measurement

machines.

( Investigated and identified the multiple causes of a post-molding

defect and implement process and procedure changes to prevent future

occurrences.

( Researched and evaluated appropriate environmentally friendly

chemicals for the removal of raw material from optical inserts without

creating additional defects.

Team Leader Video Optics Molding 1992-1996

Supervised production teams manufacturing optical systems for the CRT

projection television market.

. Set priorities to ensure production schedule was achieved and

communicated shift performance to management.

. Identified areas of improvement or scrap reduction and implemented

changes after any impact had been studied and communicated.

. Conducted safety training, semi-annual and annual performance reviews as

well as approving vacations.

. Conducted team-building sessions to aid teams in addressing and resolving

team conflict to guide the team to a self-directed level.

. Developed a workweek schedule for a 24-hour operation using 4 shifts.

Assessed and addressed team needs during transition.

Rohm and Haas Kentucky, INC., Louisville, KY

1988-1990

Chemical Engineering Intern 1988-1990

Provide technical support for lab and reactor and dryer production untis

. Record, monitor and analysis SPC and SQC data from spray dryer process

and reactor process and submit any subsequent recommendations to

management.

. Train operators on newly installed or modified equipment.

. Set priorities to ensure production schedule was achieved and

communicated shift performance to management.
