摘要

依据现有仿真加工方法难以获得趋近于实际加工所得齿面的仿真模型,为此提出一种高精度的插齿仿真加工方法。该方法基于CATIA平台,通过建立刀具与齿坯模型,分析刀具与齿坯的空间运动关系,结合CATIA内平移、旋转、布尔运算等命令与二次开发功能,完成了圆柱直齿轮的高精度插齿仿真加工;通过测量标准渐开线与仿真模型齿面间法向距离,完成了齿面精度测量并与实际加工参数相印证。最后,将仿真模型进行重构,并将仿真模型与重构模型分别进行有限元求解,通过将仿真模型与重构模型求解结果进行对比,验证了方法所得仿真模型的有效性。

Abstract

The actual tooth surface is hardly obtained utilizing the existing simulation machining method. Therefore,a highprecision simulation machining method for gear shaping is proposed. Based on the CATIA platform,the spatial motion relationship between the cutter and the gear blank is analyzed by establishing the model of the cutter and the gear blank. The high-precision insertion of the cylindrical spur gear is completed considering the commands of CATIA translation,rotation,Boolean operation and secondary development functions. The tooth surface accuracy is confirmed with the actual processing parameters by measuring the normal distance between the standard involute and the tooth surface of the simulation model. Finally,the simulation model is reconstructed. The simulation model and the reconstruction model are separately solved by finite element. By comparing the simulation model and the reconstruction model solution results,the effectiveness of the simulation model obtained by this method is verified.
