“In 2010 P&W delivered about 55 engines a month. In 2017, that number grows to about 100 engines a month. And in 2024, it continues to climb to about 158 engine deliveries a month, she said.

“And I’m doing that with 20-year-old technology and 20-year-old manufacturing processes and a very well-seasoned workforce” that adds significant complexity to the digital manufacturing transformation of the East Hartford, CT-based firm, Hagerty  said during a panel talk on best practices.

“So the challenges ahead of me are steep.”

In an interview with Smart Manufacturing magazine after the panel discussion, Hagerty said she is “fresh into the exploratory phase” to find products and services her firm needs. She has mapped out her requirements.

“Now, I’m reaching out to the service providers” and scheduling visits to firms using products and services that might well work for Pratt & Whitney.”

Automotive Engineers Look at Honing after Heat Treating

“Another dramatic change in the process itself is the move away from first hobbing a gear, then shaving it and then heat treating it. Hobbing is a multipoint cutting process that rotates both tool and workpiece in precise relations to each other. It is used to rough cut multiple gear teeth at once. “Today, automakers are hobbing gears, heat treating them and then grinding them post-heat treat. This provides a harder, more robust gear. Post-heat treat finishing of these gears eliminates distortion or changes of geometry in that gear set. The tolerance requirement after grinding is pretty critical,” he said.”
