摘　　要：本文提出一种改进的穷举算法的圆度误差评定方法,并应用于圆度误差最小区域评定中,详细阐述了改进的穷举算法的计算过程及思路流程图。该算法摒弃传统穷举算法运算繁杂的缺点,根据初始检测数据找出具有X和Y坐标的最大最小四个极值位置点,依据四个极值位置点建立初始圆度误差区域,不仅使初始误差范围接近理想区域,而且减少程序的循环次数及计算量。基于接触式影像仪软件开发平台,利用C++语言设计出圆度误差评定软件,能够快速求出圆度误差值,为现场检测提供方便。An improved exhaust algorithm is proposed and is applied to evaluate roundness error in minimum zone.The principle and steps of using this algorithm to solve the roundness error are described in detail and the mathematical formula and program flowchart are given.The traditional exhaust’s disadvantages of computing complex are overcome in the algorithm.The initial roundness error region is established at the four points that the maximum and minimum points with X and Y coordinates are located according to the initial data.This algorithm not only makes the initial error range close to the ideal region,but also the iterative time and calculation amount of the program are reduced.Based on a contact image instrument software development platform,visual C++software is used to design the roundness error evaluation software,which is able to quickly solve roundness error and provide convenience for field testing.
