《计量技术》1987年第3期发表了《大半径圆弧样板的旋转测量方法》一文(以下简称《大》文)。文章介绍了用转换坐标的方法在“万工显”上检查大半径圆弧样板,这也是一种方法,但笔者认为,ΔR_i=ΔY_i和ΔR_p=1/n sum from i=1 to n ΔR_t以及 R_t=R+ΔR_p混淆了半径误差与轮廓误差两种完全不同的概念,因此文章所得出的结论是不能成立的。
Metrology Technology, No.3, 1987, published a paper titled “Rotation Measurement Method of Large Radius Circular Arc Model” (hereinafter referred to as “Da”). It is also a way to examine the large-radius arc pattern on the “Wan Gong Xian” by using the method of converting coordinates. However, in my opinion, ΔR_i = ΔY_i and ΔR_p = 1 / n sum from i = 1 to n ΔR_t and R_t = R + ΔR_p confused two completely different concepts of radius error and contour error, so the conclusion drawn by the article can not be established.
