【 摘 要 】

The problem relating to the mechanics of orthogonal cutting with the deformation site, which is located within the contact area ahead of, below and behind the cutting tool was provided a solution. The above problem is crucial as it involves developing the mechanics of technological inheritance, which emphasizes the need for the operation-by-operation computations of the metal deformed state. The plane deformation (strain) model was adopted for the treatment with a cutter having a rounded cutting edge. Stresses, rates and deformations along the lines of current, which form the strengthened surface layer of the treated part, were computed. The patterns determining deformation accumulation and metal plasticity reserve depletion during orthogonal cutting were exposed.
