Combining experimental and FEM approaches to determine the influence of workpiece temperature on fundamental variables in the machining process
Ortiz-de-Zarate, Gorka; ARRIETA, Iñaki Mirena; Soriano Moreno, Denis; Oruna Tena, Ainara; Soler Mallol, Daniel; ARRAZOLA, PEDRO JOSE (Materials Research Forum LLC, 2024)In machining it is common practice to use lubricants to enhance machinability, resulting in improved part quality and reduced tool wear. However, emerging efforts are centered on mitigating the environmental impact of ... -
The contribution of microstructure and friction in broaching Ferrite–Pearlite steels
ARRIETA, Iñaki Mirena; ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2020)Ferrite-Pearlite (FP) steels are used in many automotive components. However, their machinability in low cutting speed processes appears to be highly dependent on their metallurgical state. An experimental approach combining ... -
In-SEM micro-machining reveals the origins of the size effect in the cutting energy
Ortiz-de-Zarate, Gorka; Sela, Andrés; ARRIETA, Iñaki Mirena; ARRAZOLA, PEDRO JOSE (Springer Nature, 2021)High-precision metal cutting is increasingly relevant in advanced applications. Such precision normally requires a cutting feed in the micron or even sub-micron dimension scale, which raises questions about applicability ... -
Influence of Microstructure on Chip Formation when Broaching Ferritic-Pearlitic Steels
ARRIETA, Iñaki Mirena; ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2017)Broaching is a specific process characterized by relatively low cutting speeds and uncut chip thicknesses. The latter is in the range of 0.1 to 0.25 mm in the roughing section of the tool but can decrease down to 0.0015 ... -
Innovative Method dedicated to the development of a ferrite-pearlite grade regarding its MAChinability (IMMAC): final report
ARRAZOLA, PEDRO JOSE; Soler Mallol, Daniel; Aristimuño, Patxi Xabier; Saez de Buruaga, Mikel; ARRIETA, Iñaki Mirena (Oficina de Publicaciones de la Unión Europea, 2019)Ferrite-pearlite (FP) steels are the most common material for engineering and automotive industries (gear box parts, crankshaft, connecting rods, injection parts…). Without any extensive research, considering the different ... -
A mechanistic model to predict cutting force on orthogonal machining of Aluminum 7475-T7351 considering the edge radius
Ortiz-de-Zarate, Gorka; ARRIETA, Iñaki Mirena; Soriano Moreno, 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 ...
