Investigations of surface textures produced by oblique

Investigations of surface textures produced by oblique

Findings: This investigation confirms that oblique machining allows producing surfaces with lower surface roughness and, in some cases, with attractive service properties. The main conclusion is that oblique cutting operations can reduce machining times and partly eliminate grinding operations, especially in the machining of hardened materials.
