FEM-based prediction of workpiece transient temperature distribution and deformations during milling [PDF]

open access: yes, 2018
In high-speed dry milling of thin-walled parts, the cutter-workpiece temperature rises asymptotically with cutting speed, causing excessive cutter tooth wear and workpiece thermal expansion, which in turn reduces the cutter life and produces dimensional ...
