Determining the force formulas while orthogonal shaped turning by tools with convex radial cutting edge [PDF]

E3S Web of Conferences, 2023
Orthogonal shaped turning is a non-free cutting process, because the main geometric and force parameters are variable while radial infeed of a tool: side cutting edge angle (SCEA), width and thickness of cut, rake angle and flank angle etc..

Shearographic Detection of Internal Defects in Austenitic Stainless Steels

Metals, 2022
Despite the formation of a passive layer, corrosion also occurs in austenitic stainless steels. One of the most common and most dangerous types is pitting corrosion, in which the material beneath the surface is completely dissolved.
