Abstract

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.

切削系统中刀具变形的动力学

摘要

考虑了切削系统在变形过程中变形位移的动态重组。在当前工作中，参数演变被视为与机器区域中不可逆的能量转换相关的自然过程，而不是因为参数的指定变化（例如，工件刚度）而导致动态重组。在这种情况下，在过程中形成的动态关系取决于在工具面与工件接触时以及在切屑形成区域中不可逆转变的功和功率。因此，这种关系的参数将取决于这些区域中不可逆变换的功和功率轨迹。一方面，参数取决于这些轨迹。在另一，这些参数的变化会影响不可逆转换的工作和功效。在当前的工作中，目标是对该功能耦合的动态系统进行建模。
