开式模锻是一种通过工件的反复增量塑性变形来制造产品的工艺。通常，工件由机械手保持，机械手可以通过冲压机的模具之间的程序控制来定位工件。零件程序是根据经验得出的参数生成的，称为扩展系数，其值受到一些争议。在这项工作中，我们演示了如何处理信息可以被用于在真实的时间，以获得一个给定的工件，因为它正在形成的实际扩散系数。这些测量和计算发生在真实的时间，并可用于重新生成零件程序，以优化成形过程，或可用于自适应地控制工件的每个增量变形。
Open die forging is a process in which products are made through repeated, incremental plastic deformations of a workpiece. Typically, the workpiece is held by a manipulator, which can position the workpiece through program control between the dies of a press. The part programs are generated with an empirically derived parameter, called the spread coefficient, whose value is subject to some contention. In this work, we demonstrate how process information can be used in real time to derive the actual spread coefficient for a given workpiece as it is being formed. These measurements and calculations occur in real time, and can be used to regenerate part programs to optimize the forming process, or can be used to adaptively control each incremental deformation of the workpiece.
