5-axis tool path smoothing to improve machine tool motion

  • 摘要: 建立了五轴数控加工刀轨光顺优化模型,改善了线性插补方式下拐角过渡运动中的机床加速度情况。考虑了5个轴加速能力的差异,以轴加速度比,即轴实际达到的最大加速度与其允许最大加速度的比值,来衡量轴的加速度情况,以5个轴加速度比的平方平均数在整体上衡量机床的加速度情况,降低该值可提高机床运动平稳性。采用最短距离线法在初始刀轨的各切触点处建立了刀轴偏航角和俯仰角的可行域,使光顺后的刀轨满足残高和无过切要求。实例表明:该方法可有效光顺五轴数控加工刀轨,改善机床加速度情况,提高机床运动平稳性。
