Tozawa等人提出了一种在机床上测量工件直线度的顺序点法。该装置非常简单，但与标准技术相比，其误差并不总是很小。为此，本文提出了一些改进的方法来纠正这种误差。然而，这些技术在提高测量精度方面并不总是有效的，因为误差与其因素之间的关系并不清楚。本文给出了描述序点法及其误差的基于渐变函数的数学函数及其解法。这些函数很容易澄清错误。分析结果表明，传感器位置标定误差引起的误差远大于测点随机测量误差引起的误差。
A sequential point method was proposed by Tozawa et al. to measure workpiece straightness on machine tools. The apparatus is very simple, but its error is not always small in comparison with standard techniques. Therefore, some improving techniques to correct the error were reported. However these techniques are not always effective in improving the measuting accuracy because the relationship; between the error and its factors were not clarified. This paper thowed the mathematical function based on gradual functions and the solutions to describe the sequential point methods and its error. The functions clarify the error easily. According to the analytical results, the error caused by calibration error of sensor position is much larger then the error caused by the random measuring error of the measuring point.
