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.
