- Abstract:
- This paper presents a new multi-probe method for accurately measuring straightness profiles of cylinders. This scanning probe method is developed from the traditional three-probe method, which can measure the profile accurately without the influence of motion errors of the scanning stage. Two sets of three-probe method sensor units are used in the developed method so that the zero-adjustment errors between the probes can be evaluated. The two sensor units are placed in the two sides of the cylindrical workpiece and are used to scan the two opposed generatrices of the cylindrical workpiece simultaneously. The workpiece is then rotated 180 degrees and scanned by the probe units again. The zero-adjustment error, as well as the straightness profiles of the workpiece can be accurately evaluated from the output data of the two measurements. The effectiveness of this method is confirmed by theoretical analyses and experimental results. The problem in another method, which was previously used by the authors to measure the zero-adjustment error between the probes, is also discussed.
