On the analysis of cutting process mechanics. Cutting with a flattened edge tool

The paper analyses the cutting mechanics of strain-hardening material with the flattened cutting edge tools. The authors present the cutting pattern and velocity vector diagram, according to which the cutting process is regarded as combination of two simultaneous acts of plastic deformation: chip formation and machined surface smoothing. The analysis is performed by strain energy method with the use of extreme principles of deformation mechanics. The authors obtained the physical quotations which describe the cutting mechanics in real-life conditions of contact friction subject to the tool geometrical parameters, including the dulling radius of the cutting edge.
