N2 - 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.
