Experience Summary

35 years of experience designing machining fixtures for Numerical Control lathes and mills, large and small assembly fixtures, automated tooling, weld fixtures, quality gages, test equipment, inspection fixtures, lifting fixtures, transportation dollies, and shipping containers.

Led tool design efforts by allocating work as needed to achieve schedule while meeting safety, cost and ergonomic goals.

Worked with cross functional teams obtain new work and create production lines.

Professional History

Senior Tool Design Engineer, Babcock and Wilcox Clinch River, Oak Ridge, TN, October 2007 – Present

· Led Oak Ridge tool design efforts for the American Centrifuge Machine project to produce 400 finished assemblies per month. Designed tooling a for robotic machining cell utilizing vacuum chucking and pneumatic cylinders to allow machining of large, tight tolerance aluminum parts at a rate of 20 per day. Also designed robot grippers and air sensing features to ensure proper part seating. Designed an automated tool using liquid nitrogen, heating elements, pneumatic grippers and stepper motors to perform a thermal shrink fit assembly of parts. Designed tool to ensure consistent preload of an assembly by monitoring stretch of the part with linear transducers instead of torque values. Frequently worked with tool makers and shop personnel to ensure proper tool function, refine producibility and enhance the ergonomics of tools. Participated in Kaizen, Six Sigma, and brainstorming events for streamlining processes. Reviewed product designs for manufacturability. Created PowerPoint presentations to demonstrate tool concepts including a presentation to management to obtain approval to create a tracked assembly line with dollies each containing 2 large composite tubes (about 2ft in diameter by about 43ft long) to reduce manual handling and also eliminate major crane moves by creating a stand up fixture to avoid adding a new overhead crane.

Senior Tool Design Engineer, Boeing Oak Ridge, Oak Ridge, TN,

May 1984 – October 2007

· Used CATIA 3D modeling system and CIMLINC 2D software to design machining fixtures, assembly jigs, drill fixtures, weld fixtures, check fixtures and transportation dollies for various military and commercial airplane programs. Reduced the total machining time from 40 hours (per part) to 5 hours (per pair of parts) for the cast titanium engine mounts of the 767 airplane by designing a semi-automated 5 position tool for a Matsurra twin spindle Numerical Control mill to machine the part with hydraulic clamping that would retract as the cutter approached the clamp and then extend the clamp after the cutter had passed. Reduced cost by instituting the use of standard dovetail and gripper holding fixtures in excess material of part to eliminate the need for customized milling fixtures. Designed ergonomic carts for large assemblies (8ft x 8ft by 10ft) to allow easy inversion of the assembly for installation of lower parts and painting of the completed assembly. Designed floor mounted drill fixtures utilizing air feed drill heads to prepare honeycomb panels for installation of nutplates. Created large assembly jig to hold critical features while assembling the floor, side , front, back panels, top canopy, and pivot arms of the turret of the Avenger air defense system that is mounted on a military Humvee.

Tool Design Engineer, The Boeing Company,

Seattle/Renton, WA, September 1978 – April 1984

· Responsible for tooling required to maintain critical door hinge line positions during field removal and reinstallation of outer skin of the tail section by AOG (Airplane On Ground) team emergency revision of the first 11 - 757 airplanes produced. Designed overhead lifting equipment, and in-plant dollies and stands for the 757 and 767 commercial airplane programs. Designed a lifting fixture that could be shipped in a crate (4ft X 2ft X 2ft), and be quickly assembled at a remote location with the capability to remove a wing from a commercial jetliner. Sent with team to San Diego, CA to move the 767 AWACS (radome) airplane assembly line to Renton, WA and designed single point lifting fixtures to replace double crane lifts with single crane lifts of the body sections. Designed mill fixtures, lathe fixtures, mold dies and manual drill jigs on various defense programs including the Air Launched Cruise Missiles and MX ballistic missile.
