摘　　要：自由曲面铣削已成为柔性制造的重要加工技术,针对齿轮自由铣削圆柱齿轮的齿形误差进行了研究。基于空间成形铣削理论建立了基于齿轮表面几何特征的铣刀路径的数学模型,研究了铣刀类型、铣刀进给策略、齿轮基本参数等加工参数对齿形误差的影响。最后在标准立铣床的通用多轴加工中心上进行了实验验证。实验结果表明,在提供通用加工中心的前提下,自由铣削齿轮是制造高质量齿轮的一种经济有效的解决方案,研究结果可为自由曲面铣削方法的最佳加工参数选择提供理论依据。Free form surface milling has become an important machining technology of flexible manufacturing.The tooth profile error of gear free milling cylindrical gear is studied.Based on the spatial forming milling theory,the mathematical model of milling cutter path based on the geometric characteristics of gear surface is established,and the effects of milling cuttertype,milling cutter feed strategy and gear basic parameters on tooth profile error are studied.Finally,the experimental verification is carried out on the general multi axis machining center of the standard end milling machine.The experimental results show that on the premise of providing a general machining center,free-form milling gear is an economic and effective solution for manufacturing high-quality gears.The research results can provide a theoretical basis for the selection of the best machining parameters of freeform surface milling method.
