    © 2018, Fuji Technology Press. All rights reserved. An on-machine measurement method, called the square-layout four-point (SLFP) method with angle compensation, for evaluating two-dimensional (2-D) profiles of flat machined surfaces is proposed. In this method, four displacement sensors are arranged in a square and mounted to the scanning table of a 2-D stage. For measuring the 2-D profile of a target plane, height data corresponding to all measuring points are acquired by means of the raster scanning motion. At the same time, pitching data of the first primary scan line and rolling data of the first subsidiary scan line are monitored by means of two auto-collimators to compensate for major profile errors that arise out of the posture error. Use of the SLFP method facilitates connection of the results of straightness-measurements results obtained for each scanning line by using two additional sensors and rolling data of the first subsidiary scan line. Specifically, the height of a measuring point is calculated by means of a recurrence equation using three predetermined height data for adjacent points in conjunction with data acquired by the four displacement sensors. Results of the numerical simulation performed in this study demonstrate higher efficiency of the SLFP method with angle compensation. During actual measurement, however, it is difficult to perfectly align inline the origin height of each displacement sensor. With regard to the SLFP method, zero-adjustment error is defined as the relative height of a sensor’s origin with respect to the plane comprising origins of the other three sensors. This error accumulates in proportion to number of times the recurrence equation is applied. Simulation results containing the zero-adjustment error demonstrate that accumulation of the said error results in unignorable distortion of measurement results. Therefore, a new self-calibration method for the zero-adjustment error has been proposed. During 2-D profile measurement, two different calculation paths – the raster scan path and orthogonal path – can be used to determine the height of a measurement point. Although heights determined through use of the two paths must ideally be equal, they are observed to be different because accumulated zero-adjustment errors for the two paths are different. In view of this result, the zero-adjustment error can be calculated backwards and calibrated. Validity of the calibration method has been confirmed via simulations and experiments.

  • A novel compensation method of zero-adjustment error in flatness measurement using serial four-point method

    Shimizu H., Yamashita R., Hashiguchi T., Miyata T.

     概要を見る

    The authors proposed a novel on-machine measurement method for evaluating three-dimensional profiles of machined flat surface: square layout four point (SLFP) method with angle compensation. The SLFP method enables to connect the results of straightness measurements of each scanning line by using additional two sensors and an angle sensor. Numerical simulation showed that the accumulation of zero adjustment error of displacement sensors makes unignorable distortion on the measurement results. Hence, a new calibration method for zero adjustment error was proposed and the validity of the method was confirmed by an experiment.

    Non-contact supports involving air or magnetic forces are used as guide supports for linear motion mechanisms. In the present study, non-contact supports are generated using the effect of the static pressure force produced by a squeezed air film. The linear slider is supported at just two of its ends. Applying a different excitation amplitude to the two transducers leads to a difference in the floating height at either end of the slider due to the different air-film thicknesses. This causes the slider to tilt, which produces a propulsion force due to the dead load. An experimental apparatus with a flat plate slider was developed and its floating characteristics were examined. In addition, the propulsion force was measured for sliders with different weights. The results indicated that the floating height was 2 to 3 times the excitation amplitude. The slider was capable of travelling all over the movement stroke. The traveling force increased with increasing slider weight, and was about 0.15-0.35 mN. The measurement results were in good agreement with theoretical calculations. Thus, the present study showed that the slider could be successfully supported in a non-contact state and was capable of movement under the influence of a propulsion force generated only by the dead load.

    <p>In this study, we developed a multi cantilever device for straightness measurement using the three point method. This device has three triangular cantilever works as displacement sensors. When the displacement is given at the probe placed at the end of the cantilever, stress arises in the cantilever. Displacement is measured by detecting the stress change using two piezo resistances at the root of the cantilever. This paper presents the results of sensitivity evaluation of improved device models. To improve the sensitivity, we considered the shape to make stress concentration in the strain detecting section of the device, and examined the effects by the finite element method. As a result, it was confirmed that transverse notches on both sides at the root of the cantilever and a rectangular hole between the piezo resisances are effective for sensitivity improvement and crosstalk reduction. Furthermore, we also simulate models of changing thickness of each part and models of changing position of piezo resistance.</p>
