摘要
为使机床精度设计有定量的理论数值供参考，依据线性空间集合与映射的数学理论，以多体系统误差建模理论为基础，建立了机床几何误差综合作用时的产品加工质量近似模型。运用蒙特卡罗法对满足加工精度要求的产品进行关键参数数据抽样，从而依据近似模型逆向推导数控机床各轴几何精度。以螺旋锥齿轮铣齿机各轴精度逆设计为例，近似模型以显式的方式揭示了机床几何误差和齿面加工误差间的定量关系，可有效地依据齿轮精度要求逆向推导机床各轴几何精度。
Usually machine geometry precision design is preformed depending on human experience but not reference data form design theory. To learn numerical effect an approximate model of relationship between machine geometry precision and product machining precision is provided based on muhibody theory. The analysis results by Monte Carlo sampling would deduce geometry precision of each axis in machine. Taking geometry precision design of spiral bevel gear milling machine as an example, the approximate model well explains effect of machine geometry error on gear product surface machining quality by explicit. Then geometry precision of each axis is obtained by mapping from tooth surface machining precision.
