以曲面的最小二乘准则为基础,用小误差变化矩阵,从曲面的局部构造出发研究包括六项对刀误差和刀具宽度误差在内的七项误差对加工的影响,建立二次回转曲面铣磨加工的误差模型,并分析模型的误差。
Based on the Least Squares (LS) criterion of curved surfaces, the influence of seven errors including tool setting error and tool width error on machining was studied from the local structure of curved surfaces by using the small error variation matrix, and the secondary rotary surface milling Grinding the error model and analyzing the model error.
