平行车削具有提高加工生产率的潜力，从而降低总生产成本。然而，由于复杂的相互作用的工具和工件，稳定性的过程中，对颤振的振动往往会下降，因此，一个成功的颤振避免/抑制必须实现。最近，我们的研究小组通过在柔性工件的圆周方向上振荡两个刀具同时保持等间距来抑制切屑面平行车削中的颤振。然而，有不足的讨论和实验验证周围的刀具摆动运动（TSM）的优化设计。本文提出了一种基于主轴变速技术的刀具摆动并联车削设计方法。在改变TSM设计参数的同时进行了一系列实验，以支持所提出的设计方法。并对实验结果进行了深入的讨论。本研究的结果提供了足够的信息，适当调整的TSM过程中有效的颤振抑制在实际应用中。
Parallel turning has the potential in enhancing the machining productivity and consequently reducing total production costs. However, due to the complex interaction of tools and workpieces, the stability of the process against chatter vibration is often decreased; hence, a successful chatter avoidance/suppression must be achieved. Recently, our research group suppressed the chatter in the shred-surface parallel turning by oscillating two tools in the circumferential direction of a flexible workpiece while keeping the equal pitch. However, there are insufficient discussion and experimental verification surrounding the optimal design for the tool swing motion (TSM). This paper presents a design methodology for the tool swing parallel turning based on the analogy with the spindle speed variation (SSV) techniques. A series of experiments were conducted while varying TSM design parameters to support the proposed design method. In-depth discussions regarding the experimental results were also carried out. The results of this study provide adequate information for properly tuning the TSM process for effective chatter suppression in practical applications.
