Description
Summary:The dynamic reorganization of the deformational displacements in the cutting system during its evolution is considered. In the present work, instead of regarding dynamic reorganization as due to specified change in the parameters—for instance, the workpiece rigidity—parameter evolution is treated as a natural process associated with irreversible energy transformation in the machine zone. In that case, the dynamic relationships formed in the process depend on the work and power of irreversible transformations at contact of the tool faces with the workpiece and also in the chip-formation zone. Therefore, the parameters of such relationships will depend on the work and power trajectories of the irreversible transformations in those regions. On the one hand, the parameters depend on those trajectories; on the other, change in those parameters affects the work and power of the irreversible transformations. In the present work, the goal is to model this functionally coupled dynamic system.
