Modeling of Thermal Processes in a Technological System during Electromechanical Processing

The article presents mathematical models of thermal processes combined methods electromechanical processing, which are based on the heat conduction equations, take into account thermophysical properties (thermal diffusivity, capacity, conductivity and transfer), initial boundary conditions, technological other features studied processing methods. In view fact that (EMT) is characterized by a process with volumetric release zone, sufficiently small dimensions high intensity, it assumed determination temperature fields can be carried out using superposition principle. this case, main factors affecting amount propagating contacting bodies intensity removal, bodies, speed their relative movement. Dependences proposed allow one to describe in volumes parts subjected deformation during have significant geometric parameters ensure sufficient removal from treated surfaces part. It has been established case dimensions, insignificant becomes necessary accumulation heat, will lead general increase system decrease efficiency hardening process. derived dependencies form equations restrictions make possible determine “working tool” - “local microvolume surface layer”, while these presented relationships linear formulation coefficients. theoretically experimentally confirmed performed experimental studies adequacy used calculate temperatures local microvolumes layer.
