THE TRANSFORMATION OF THE ROUNDNESS PROFILE

S. Adamczak, D. Janecki

Abstract

Reference (especially two- and three-point) methods could not be applied to the accurate measurement of roundness profiles because of various drawbacks. Theoretical and experimental studies have proved that the only way to eliminate these drawbacks is to mathematically transform the profile measured by a reference method into the real profile. The transformation, whose fundamentals are presented and discussed in this work, enabled the development of an original computer program. The mathematical model of the transformation was statistically tested by means of a specially developed computer measuring system, and the results provided basis for the construction of measuring systems applicable to accurate measurements of roundness profiles directly in production.
