“…In 1986, Tanaka and Sato analyzed the STP method extensively and developed the sequentialthree-points (STRP) which can measure both straightness and yawing error of the slide [16]. With more than two probes, some EST has been applied to avoid the scanning error from the probe and shorten the sampling interval to obtain better results [17][18][19][20][21]. Under the mature use of EST, the straightness of the slide is measured on a flat plane with little profile variation.…”

This paper describes an improved error separation technique (EST) for on-machine surface profile measurement which can be applied to optical lenses on precision and ultra-precision machine tools. With only one precise probe and a linear stage, improved EST not only reduces measurement costs, but also shortens the sampling interval, which implies that this method can be used to measure the profile of small-bore lenses. The improved EST with stitching method can be applied to measure the profile of high-height lenses as well. Since the improvement is simple, most of the traditional EST can be modified by this method. The theoretical analysis and experimental results in this paper show that the improved EST eliminates the slide error successfully and generates an accurate lens profile.

In this paper, a method is introduced to remove the counting errors of electronic counting instruments, which contains two aspects to remove the errors caused by outside interference and to remove the counting errors caused by quality error of the object respectively. Counting errors of object can be removed effectively by program of software system. As a result, it’s proven to be effective and stable by applying it into practice.

In order to solve the problem that the flatness error contour curve of the guideway mounting surface on machine tools can not be intuitive description, a novel method is proposed in this paper. The principle is to divide the measured surface with a certain length into several short surfaces with overlapping region, and the segmented surfaces are measured respectively, then the flatness error contours of the segmented surfaces can be obtained, finally, the segmented flatness error contours are spliced together to reconstruct the flatness error contour of the entire surface. On this basis, the detection instrument is designed, the detection principle is given, the benchmark plate is customized to identify the starting position and ending position of measurement, the reference surface and the measured surface are measured respectively in combination with the detection instrument and the benchmark plate. Then, an algorithm is developed to convert the distance difference between the reference surface and the measured surface into the flatness error contours of segmented surfaces. Next, using the geometric relationship between overlapping region of segmented flatness error contours, an algorithm is studied which can splice these segmented flatness error contours and reconstruct the flatness error contour of the entire surface. Meanwhile, mathematical models of the algorithms are established, and the measurement experiment is carried out. The results demonstrate that this method can reconstruct the flatness error contour of long surface accurately.
