Cylindrical Profile

Cylindricity is a kind of three-dimensional form distortion of a cylinder. An accurate in situ measurement of cylindricity is relatively complex because measuring and reconstructing cylindrical profile and evaluating out-of-cylindricity should be involved. Any method of in situ measuring cylindricity must solve a common issue, i.e., to eliminate spindle error motions and carriage error motions during measurement and reconstruction. Thus, error separation techniques have played an important role in in situ cylindricity measurement through multipoint detections. Although several valuable five-point methods for in situ measurement of cylindrical profile have been proposed up to present, namely the parallel scan, spiral scan, and V-block scan, there are obvious differences in many aspects, such as the arrangement of probes, error separation model, reconstruction method, adaptability to service environment, accuracy and reliability in practical application, etc. This paper presents the evaluation of their advantages and disadvantages in theory and the actual measurement based on the standard ISO 12180. Suggestions for best meeting the requirements of modern manufacturing and the most prospective one for industrial applications are also given.

Roundness Measurement

This paper introduces a spindle error separation technique called orthogonal mixed method. The problem of harmonic suppression is solved by the orthogonal mixed method, which exists in the process of measurement based on three point method.The measuring system consisting of a displacement sensor and a angle sensor is developed for spindle error and roundness measurement. Two sensors, which are placed in the same plane perpendicular to the spindle axis, are mutual into 900. The principle of the critical angle method of total reflection are used by two sensors to separate rotation error from spindle error. Above all, the measured results show that this method indeed solve the problem of harmonic suppression, make the results of measurement more accurate.
