Cleveland, Ohio – Lockheed Martin's innovation in manufacturing technology has led to four awards from the Manufacturing Leadership Council, whose members are manufacturing, production, design, and engineering executives brought together by Frost and Sullivan. The Council focuses on the intersection of advanced technologies and the business, identifying growth and improvement opportunities in the operation, organization and leadership of manufacturing enterprises along their journey to Manufacturing 4.0.

Now in its 13th year, the Manufacturing Leadership Awards honor manufacturing companies and individual manufacturing leaders that are shaping the future of global manufacturing.

"It is an honor to receive these awards for Engineering and Production Technology Leadership," said Joe Rappisi, vice president for Production Operations at Lockheed Martin Aeronautics, Fort Worth, Texas. "Lockheed Martin employees are constantly looking for improvements and cost efficient ways of doing business. These awards confirm these individuals' desire to drive change."

Rick Luepke, a Lockheed Martin engineering Fellow, was awarded the Visionary Leadership Award, and Lockheed Martin won three awards in the Engineering and Production Technology Leadership category for its ultrasonic hole cutting tool, forced mechanical oscillation drilling technology, and mold-in-place inlet coatings project.

Luepke was recognized for his extensive impact and achievements in the manufacturing industry. He has 12 patents, either awarded or under file with the United States Patent and Trademark Office. In addition to his pioneering achievements and awards, Luepke has integrated more than $100 million of capital equipment into Lockheed Martin's production facility, while delivering program savings exceeding $100 million. His leadership led to the development and integration of multiple breakthroughs in technology and manufacturing processes, like the mold-in-place system, where he served as the chief architect.

Better hole cutting
The manufacturing process for military aircraft requires drilling thousands of holes through various substrate materials in order to access fasteners holes used to attach panels. The previous practice for cutting these holes resulted in excessive debris, required the use of a downdraft table and typically resulted in a dull cutter after only a few holes. Lockheed Martin participated in an Office of Naval Research/Defense-wide Manufacturing Science & Technology funded Contract Research and Development (CRAD) effort to develop a portable, hand-held, ultrasonic hole-cutting tool capable of cutting fastener access holes in the various substrates. Through the CRAD effort and a production pilot, followed by design optimization, the team released production units that are capable of reducing the per hole cut time by 85%.

Forced mechanical oscillation drilling
Deep stack drilling can be defined as drilling through mixed materials with continuous drilling through material that is 1.5" and deeper. Difficult-to-drill aerospace materials, stacked in combinations, combined with engineering requirements and large chip formation from drilling make deep stack drilling a challenging task. With forced mechanical oscillation drilling, which leverages a controllable mechanical oscillation, large chips are broken into small, lightweight, manageable chips that are easily evacuated. Integration of this new technology has enabled Lockheed Martin to significantly decrease drill times, improve hole quality, and increase tool life for all deep-stack applications.

Mold-in-place inlet coatings
The mold-in-place inlet coatings project fuses collaborative robotics, advanced metrology, and conformable composite tooling into a system that can mold coatings directly to an aircraft's contoured surface. Originating from an Air Force Research Laboratory funded CRAD, this system serves as an alternative to robotically sprayed coatings, which contain high levels of volatile organic compounds, require significant preparation, and lengthy application times in a spray booth. The integrated advanced metrology technology provided a solution that allows the robot to establish its position relative to the aircraft and adjust its kinematics to place the mold tool accurately. This new coating system and process reduces touch labor 50% and allows concurrent work to be performed on the aircraft eliminating a bottle neck for F-35 production.
