Advanced measurement techniques to improve predictive modelling of cutting processes by using inverse simulation

Sela Barrial, Andres (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2021)

Machining is one of the most widely employed manufacturing operations, contributing from 3 to 10% of GDP in developed countries. Despite this prevalence, tools and cutting conditions are often chosen on a trial-and-error ...
Evaluation of different flow stress laws coupled with a physical based ductile failure criterion for the modelling of the chip formation process of Ti-6Al-4V under broaching conditions

Ortiz-de-Zarate, Gorka; Saez de Buruaga, Mikel; Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Elsevier, 2019)

During the machining of Ti-6Al-4V the changing deformation mechanisms produce a complex microstructure of segmented chips, which directly influenced tool-wear and process stability. Numerical simulation could give an insight ...
A mechanistic model to predict cutting force on orthogonal machining of Aluminum 7475-T7351 considering the edge radius

Ortiz-de-Zarate, Gorka; Arrieta Galdós, Iñaki Mirena; Soriano, Denis; Aristimuño, Patxi Xabier; Medina Clavijo, Bentejui; ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2019)

The ploughing force related with action of edge radius is an important factor which influences flow stress, chip formation or surface integrity. Some fraction of the cutting forces are called parasitic (additional) forces ...
