Conclusions
This paper shows that is possible to extend white light interferometers to measure both continuous or stepped cylindrical surfaces. The optical setup is modified by introducing a high precision 45° conical mirror to optically transform rectangular coordinates into cylindrical coordinates. A prototype of this new design of interferometer was built, aligned and calibrated using a master cylinder as reference. At the current stage the prototype of the interferometer is not optimized, but it was possible to perform preliminary evaluations and apply it to measure pistons of gas compressors. The typical measurement time ranges from three to five minutes. It was found an overall expanded measurement uncertainty of about 1.0 µm, what is sufficient for several industrial applications.
That configuration opens possibilities for new applications of high interest in mechanical engineering such as wear measurement in cylindrical surfaces. Either continuous or stepped cylindrical surfaces can be measured. The uncertainty achieved at this stage of development is about 1.0 µm. The authors believe that improvements in the scanning mechanism and the use of a better reference cylinder can reduce the expanded uncertainty to something below 0.3 µm. Current developments efforts are focused in the measurement of inner cylindrical geometries and development of algorithms for wear measurement.
