TOLERANCE-FIT OF GEOMETRIC ELEMENTS AND SCULPTURED SURFACES AND PROFILES

W. Lotze, U. Lunze

Abstract

For quality control in the case of workpieces measured by CMM both a sufficient number and location of measuring points and the correct evaluation for determining the minimum deviations of size, position and form for the entire workpiece guaranties economic manufacturing. The idea to fulfil this general objective function opens a new set of tasks besides of the well known data fitting for individual features. The paper deals with new solutions for data fitting of compound features with partly different tolerances oriented on the minimum zone objective function.
