The article demonstrates the possibilities of effective using the energy method of power balance for design of precise forging processes by extrusion. The classification of kinematic modules according to the main characteristics has been carried out, which increases the efficiency of their using at the stage of developing calculating schemes of the processes. The recommendations are given for rational using the unified kinematic modules, taking into account the limitations of their combination with adjacent kinematic modules, the possibility of varying the shape and location relative to the axis of symmetry. The base of unified kinematic modules of trapezoidal and triangular shapes has been expanded and recommendations in terms of rationality and limitations of their using at developing calculation schemes for the processes are given, taking into account operational configuration changing of the tool (presence or absence of chamfer and rounding). This made it possible to quickly control of complex-profile parts forming for the incorporated combined extrusion processes with several degrees of freedom of metal flow, which take place in self-regulating mode. A software module has been developed to systematize the base of unified kinematic modules, the components of their calculation and recommendations for using and the set of energy calculation models for the processes of precise forging by extrusion with prediction of the power mode and forming of the part. The promising directions for improving design of precise forging processes by extrusion based on energy calculation models are outlined, that will contribute to the introduction of incorporated combined extrusion processes in manufacturing.
