Conquering the Heat: A Machinist’s Deep Dive into High-Performance Aluminum CNC Machining
Moving beyond basic feeds and speeds, this article reveals the nuanced battle against thermal distortion in high-tolerance aluminum parts. Drawing from a decade of aerospace and medical projects, I detail a proven, multi-faceted strategy for managing heat, from alloy selection to in-process cooling, backed by a case study that reduced scrap by 22% and improved surface finish by 35%.
