Stress–strain parameter prediction method for AWJ technology from surface topography

Abstract The presented publication is based on the interaction of material core and its surface during machining process with a hydro abrasive flexible cutting tool (AWJ). In AWJ technology, cold cut generated; therefore, there are no thermal stresses newly formed and, consequently, significant internal residual stresses. identifiable by directly measurable parameters: depth cut, deviation path from normal plane, roughness. These geometric parameters interdependent at each zone point simultaneously dependent proposed, indirectly parameter, K plmat . Although angle plane increases increasing ratio “material plasticity” roughness Ra remains equivalent to plane. Based proposed concept, an entirely new approach problem integrity method identification mechanical equivalents their functional transformation. solution subject fact that technological machined decomposition specifically identically “copies” properties material, i.e. records inheritance. can then be “read retrospectively” reliably accurately using recording.
