An Architecture of Component - Based CAPP Systems for Agile Manufacturing

September 1, 1996
Author(s)
Shaw C. Feng, C Zhang, Steven R. Ray
The current manufacturing planning software systems (such as computer aided process planning (CAPP) systems) are general and in a closed form, i.e., it is very difficult to modify these systems to respond to a user's dynamically changing needs. These

Effects of as-built surface with varying number of contour passes on high-cycle fatigue behavior of additively manufactured nickel alloy 718

August 5, 2023
Author(s)
Orion Kafka, Jake Benzing, Nicholas Derimow, Philipp Schumacher, Lucas Koepke, Chad Beamer, Donald Godfrey, Nik Hrabe
High cycle fatigue life of laser-powder bed fusion (L-PBF) parts depends on several factors; as-built surfaces, when present, are a particular concern. This work measures as-built L-PBF surfaces with X-ray computed tomography, and uses rotating beam
