用计算机按国际标准规定的四种圆度评定方法,作圆度评定已被广泛采用。一、圆度的数值解法及评定程序有用几何方法建立求圆度的数学模型,但不很成功。因为几何方法很难严格地按圆度评定的定义建立数学模型。我们根据区域法定义,把求圆度归结为一个优化问题,目标函数f(x)=R_(max)-R_(min)。同样,最小外接圆和最大内切圆的参
Computer using four roundness assessment methods according to international standards for roundness assessment has been widely used. First, the roundness of the numerical solution and evaluation procedures Use geometric methods to establish a roundness mathematical model, but not very successful. Because of the geometric method it is difficult to rigorously establish the mathematical model according to the definition of circularity. According to the definition of regional law, we sum up the roundness as an optimization problem, and the objective function f (x) = R max (max) -R min. Similarly, the minimum circumscribed circle and the maximum inscribed circle of reference
