Broaching: Cutting tools and machine tools for manufacturing high quality features in components
ARRAZOLA, PEDRO JOSE (Elsevier Ltd., 2020)Broaching is a unique machining process with high accuracy and surface quality, which is employed in massand batch production for the manufacture of components with highly complex geometries. It involves the use 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 ... -
Identification of interaction mechanisms during drag finishing by means of an original macroscopic numerical model
Malkorra Sarasola, Irati; Souli, Hanène; Claudin, Christophe; Salvatore, Ferdinando; ARRAZOLA, PEDRO JOSE; Rech, Joël; Seux, Hervé; Mathis, Aude; Rolet, Jason (Elsevier, 2021)Drag finishing is one of the mass finishing processes that enhances surface roughness on complex parts due to the mechanical action of abrasive media. Due to the complexity of the process, industrial practice is based on ... -
Influence of lubrication condition on the surface integrity induced during drag finishing
ARRAZOLA, PEDRO JOSE (Elsevier Ltd, 2020)Tribofinishing is one of the most popular polishing process in industry. The action of small abrasive media around parts enables to reduce significantly surface roughness and at the same time, to induce compressive residual ... -
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 ... -
Modeling of Drag Finishing: Influence of Abrasive Media Shape
ARRAZOLA, PEDRO JOSE (MDPI, 2021)Drag finishing is a widely used superfinishing technique in the industry to polish parts under the action of abrasive media combined with an active surrounding liquid. However, the understanding of this process is not ... -
Numerical modelling of the drag finishing process at a macroscopic scale to optimize surface roughness improvement on additively manufactured (SLM) Inconel 718 parts
ARRAZOLA, PEDRO JOSE (Elsevier B.V., 2022)Drag finishing is one of the mass finishing processes that enhances surface roughness on complex and rough parts produced by additive manufacturing. This paper proposes a model to simulate abrasive media flowing around the ...
