1.
The method of ellipse contour extraction based on Least-squares and elliptic roundness error;
基于椭圆最小二乘法和圆度轮廓误差评定的椭圆提取方法
2) Elliptical profile error
椭圆线轮廓度误差
3) profile error
轮廓度误差
1.
The profile of the random curve is expressed not by mathematical equation but by discrete points,which makes it very difficult to evaluate the profile error.
自由曲线的轮廓常用离散点来表示,而不是已知的数学方程,评定其轮廓度误差非常困难。
2.
For the mathematical model of profile error of surface is very complicated,and it is difficult for solving by traditional numerical method,an equal parameter lines area combined particle swarm optimization(PSO) is proposed for computing the profile error of complicated surface.
针对复杂曲面轮廓度误差计算的数学模型比较复杂,并且难以用传统数值优化方法求解这一问题,提出了一种基于微粒群算法(PSO)并结合等参数线区域来计算复杂曲面轮廓度误差的方法。
3.
The profile error is the item which applies widespread but difficult to measure and evaluate in country standard and international standard of the components shape error and position error.
轮廓度误差是零件形位公差国家标准和国际标准中应用广泛而又难于测量和评定的项目。
4) arc contour error
圆弧轮廓误差
5) measuring error/profile
测量误差/轮廓度
6) Surface profile tolerance error
面轮廓度误差
补充资料：不圆度
不圆度
ovality
buyuandu不圆度(。vality)圆形金属材(包括棒、线、管等)横断面上最大与最小直径的差值，曾称作椭圆度。在产品标准上都规定有不圆度的允许偏差，一般约为直径正负偏差之和的。.5倍，圆管坯为直径公差的。.75一0.8倍，盘条直径则规定有绝对值0.24~0.6omm。钢管外径不圆度为直径偏差之和的。.5~1.0倍，钢丝不圆度则为直径偏差之和的0.5倍。 造成不圆的原因是:轧棍、锻追模具或冷拔模具的孔型不圆，塑性加工时孔型欠充满以及孔型错牙、导板和卫板安装不正或过松、轧件入孔型不正等。 (崔峰)
