Hill Engineering is presenting about advanced manufacturing methods and their effects on residual stress at the upcoming 2017 AeroMat Conference in Charleston, SC. The event is organized by ASM International and is hosted by Arconic. Hill Engineering’s presentation will include a summary of recent programs where we evaluated the residual stress from a variety of advanced manufacturing methods. The abstract text is presented below.
To meet performance requirements for next generation aircraft and rotorcraft while maintaining the current and legacy fleet, advanced alloys, product forms and manufacturing methods are essential. Processes like machining, joining, additive manufacturing, forging, rolling, and extruding produce residual stresses. If not well understood and mitigated, these residual stresses can have negative effects on performance, including post-machining distortion and reductions in fatigue and corrosion performance. Demonstration programs within DoD have recently shown that management of residual stress can provide improvements in manufacturing throughput, cost savings, weight savings, and increased performance. Examples of residual stress, its effects, measurement techniques and mitigation methods will be presented.
