Effect of V concentration in TiSiN monolayer coating on chip formation mechanism and chip sliding velocity during dry turning of Ti–6Al–4V alloy
Autor: Ch Sateesh Kumar, Gorka Urbikain, Pablo Fernández De Lucio, Cristian Pérez-Salinas, Luis Norberto López De Lacalle, Filipe Fernandes
Publikováno v: Journal of Materials Research and Technology, Vol 32, Iss , Pp 4456-4464 (2024)
The current study examines how the self-lubricating characteristics of the novel TiSiVN coating affect the chip formation process and chip sliding velocity during the dry turning of Ti6Al4V titanium alloy. The serration bands tend to straighten at a

Topography simulation of free-form surface ball-end milling through partial discretization of linearised toolpaths
Autor: Felipe Marin, Adriano Fagali de Souza, Helton da Silva Gaspar, Amaia Calleja-Ochoa, Luis Norberto López de Lacalle
Publikováno v: Engineering Science and Technology, an International Journal, Vol 55, Iss , Pp 101757- (2024)
Free-form surfaces are commonly present in several engineering components, from molds to more sophisticated components of aeronautical engines. These parts are usually finished by machining, more specifically, ball-end milling. In this process, the c

Instantaneous contact area-based model for shear strength sensitive cutting coefficients characterization of anisotropic parts
Autor: José David Pérez-Ruiz, Luis Norberto López de Lacalle, Gorka Urbikain, Hugo Álvarez, Jovanny Pacheco
Publikováno v: Engineering Science and Technology, an International Journal, Vol 52, Iss , Pp 101650- (2024)
The anisotropic nature of laser powder bed fusion (LPBF) parts means that the cutting force coefficients obtained by linear regression or non-linear optimization methods only work for one tool position relative to the workpiece. These methods must ob

Digital Twin for Volumetric Thermal Error Compensation of Large Machine Tools
Autor: Beñat Iñigo, Natalia Colinas-Armijo, Luis Norberto López de Lacalle, Gorka Aguirre
Publikováno v: Sensors, Vol 24, Iss 19, p 6196 (2024)
Machine tool accuracy is greatly influenced by geometric and thermal errors that cause positioning deviations within its working volume. Conventionally, these two error sources are treated separately, with distinct procedures employed for their chara
