Background: An ISO standard tooth profile has a symmetric pressure angle of 20°. However, the load capacity can be increased with respect to bending and contact pressure by increasing the pressure angle on the meshing side of an asymmetric tooth. Accordingly, we analyzed the torque transmission capacity of asymmetric gears with various pressure angles. Methods: We calculated the deflection and ...

Turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. In order to obtain desired surface quality by machining, pr...

Abstract Laser oscillating welding was employed to fabricate Al-Si coated press-hardened steel (PHS) improve the element homogeneity in fusion zone. with various oscillation amplitudes (0 mm, 0.5 mm and 1.3 mm) this present. Ni foil of 0.06 thickness used as an interlayer between two tailored PHS welded. The weld morphology, elemental profile, microstructure tensile strength welded joints were ...
