“…The influence of the errors which may be enclosed in the process of producing VMDP can be eliminated by the use of 2D error separation method. 31 Moreover, it is also important to calibrate the measuring system by a cylinder standard workpiece, which would allow for improving the measurement control processes, as well as to allow for system error compensation.…”

A high-speed length measuring system for mobile and large-scale cylinder workpiece was designed and constructed. This measuring system is characterized by two stationary laser scanning systems placed on two sides of workpiece responsible for the acquisition of points of key parts. Meanwhile, for making the measuring process faster and more flexible, the virtual measurement datum planes play an important role, and are step-by-step generated according to various features of measured surface in an online virtual inspection environment. Moreover, modeling and identification of end point of workpiece are established based on height variations in its nearest neighborhood. The three-dimensional dynamic length measurement data are then obtained by calculating the displacement between end point and corresponding datum plane.The prototypal system has been tested on different real cases with several typical cylinder workpieces (length 1000 6 20 mm, diameter 50 6 25 mm). Compared with the measurement results of coordinate measuring machine, the root-mean-square errors of the measurement data are smaller than 0.035 mm. The system measurement uncertainty is better than 60.040 mm. The measuring time is less than 2 s. The proposed measuring system features high automation and high efficiency, and is most promising for on-machine applications in large geometric dimensional measurement.

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. INDEX TERMS Flatness detection, machine tool, detection instrument, flatness error contour reconstruction, contour splicing.

Non-contact thickness measuring systems can be found in a wide spectrum of technologies. In this paper, Hilbert-Huang transform method is used to analyze the real time signals of a measuring system which includes two round conveyor strings carrying a thin plate, a solar wafer as a sample under test. The vibrations of moving strings and the plate, which are sensitive to moving speed and initial tension in the string, are introduced briefly; the relevant analyses should be helpful for the system design. Using EMD-based time-domain filtering and complementary method, thickness variations and error bands are estimated for different cases. The results show that HHT method as an adaptive time-frequency method, should be potential in measurement engineering applications.
