This paper preliminarily explores the modeling of incipient cutting by (LS-Dyna) FEM software comparing the results on different material classes, including common aluminum and steel alloys and an acetal polymer. The target application is micromachining of a durable mold for mass manufacturing gecko adhesives, with challenging requirements, including undercuts and sharp tips; other cases of industrial interest are briefly reviewed. The FEM configuration is discussed and compared with experimental chip characterization experiments.

Abstract
This paper preliminarily explores the modeling of incipient cutting by (LS-Dyna) FEM software comparing the results on different material classes, including common aluminum and steel alloys and an acetal polymer. The target application is micromachining of a durable mold for mass manufacturing gecko adhesives, with challenging requirements, including undercuts and sharp tips; other cases of industrial interest are briefly reviewed. The FEM configuration is discussed and compared with experimental chip characterization experiments.File in questo prodotto:
