Abstract

Parallel turning technology has been attracting attention as an important technology to enhance the productivity of multitasking machine tools. To maximize the productivity advantage of parallel turning, chatter avoidance or suppression is one of the most noteworthy concerns. In this study, a novel chatter suppression technique using tool swing motion is provided by a feed drive system. The optimal design methodology of the tool swing motion for effective chatter suppression is also introduced based on its analogy with the spindle speed variation technique under the sharedsurface parallel turning and rigid-tool and flexibleworkpiece assumptions. The proposed method was evaluated with regard to the chatter stabilizing performance and workpiece runout as compared to conventional equal pitch turning and unequal pitch turning for chatter suppression. As a result, the proposed tool swing parallel turning exhibited a high chatter stabilizing performance without eccentricity of the workpiece and enhanced surface quality, although particular swing marks were left on the machined surface.
