In metal cutting, unbroken chips may scratch the machined surface and hinder an efficient
chip removal. Despite its relevance, the established methodologies of tool/process design …

Chip breakage is a major machinability criterion of metal cutting operations. Favorable
broken chips enable their efficient removal and prevent mechanical damages to the …

In this paper, a systematic evaluation of six ductile fracture models is conducted to identify
the most suitable fracture criterion for metal cutting processes. Six fracture models are …

Metal cutting, or simply machining, is one of the oldest processes for shaping components in
the manufacturing industry. It is widely quoted that 15% of the value of all mechanical …

In this paper a two-dimensional and a three-dimensional finite element models of unsteady-
state metal cutting are presented. These models take into account dynamic effects, thermo …

This paper appraises two major chip formation techniques in finite element (FE) simulation
of machining. The first one considers chip formation as a wedge indentation process, while …

This study is part of the ongoing research at the Department of Mechanical Engineering of
the University of Brescia. A simple orthogonal cutting operation was simulated under …

Chip breakage is one of the most important indicators for process stability in metal cutting. It
ensures efficient chip removal in automated systems and prevents mechanical damage to …

The process simulations based on FEM techniques have been investigated for many years,
some fundamental problems are still unsolved, eg the element size effect on the …

This work focuses on the effects of cutting edge geometries on dead metal zone formation,
as well as stress and temperature distributions in orthogonal cutting of P20 material using …
