Resumen:
Machining is one of the more widely used manufacturing processes in the
industry, for this reason, several studies have focused on predicting
the effect of variables related to it. In this work, the effect of the
equivalent plastic displacement on the orthogonal cutting process, using
coupled Lagrangian-Eulerian (CEL) analysis was studied. The workpiece
was considered Eulerian solid material to simulate its interaction with
the cutting tool and thus, predict material separation and chip
morphology. In the present model, the chip morphology was evaluated in
terms of the equivalent plastic displacement, segmented chip formation
was achieved without the necessity to apply a method of mesh separation
and undeleting elements during the calculation solution, which
represents an important advantage over the purely Lagrangian method.
Additionally, the cutting forces, contact length, angle of the cutting
plane, as well as stress, strain, and temperature distribution were
obtained.
