ELASTIC DEFORMATIONS IN COMPUTER AIDED TOLERANCE ANALYSIS: A FOCUS ON TWO-DIMENSIONAL CONTACT SURFACES
The analysis of fabrication deviations and elastic deformations gains more and more in importance. Presently no reliable approach of this combined simulation of both factors is available. By the example of a strongly simplified tool machine, one possible coupling concept is to be demonstrated. It is based upon the superposition of waviness functions and/or works directly with point coordinates and uses a commercial tolerance analysis system as a simulation kernel. The data of functional relevant surfaces is integrated into the software system in terms of the four statistical moments. Exemplary a deviation of concentricity of the axes of the tool carrier and workpiece carrier is determined through the method.
