Analysis of Mechanics of the Process of Cutting Hardened Material. Chip formation
The works states results of the chip formation mechanics analysis, which considered as a combination of two continuously going actions: chip formation and plastic forming of a subsurface layer; the deformed material is considered as a mechanical system with several degrees of freedom. Proposed is a common velocity vector diagram for chip formation with forming of a subsurface layer, obtained are physical equations for the forecast of chip escape velocity and deformation, pressure and force on tool surface with angled major cutting edge.
