Abstract

Incomplete or wrong definition of tolerances can cause aesthetic and functional problems. In a virtual environment the visual representation is not precise enough to reveal small deviations. Therefore a platform for haptic tolerance analysis is presented employing the human haptic sense for this task. The requirements on the system are the precise representation of geometry, realistic simulation of physics and stereographic visualization. In addition to the systems layout, experiments to acquire data about the system accuracy for gap and flush analysis are discussed. Finally, a case study for the analysis of sheet metal parts is presented. It is shown that haptic systems offer a high accuracy and extend the immersion in VR-environments.

DESIGN 2008 - 10th International Design ConferenceDESIGN 2008 Conference was founded on the continuous development of organization and evaluation procedure that resulted in a capacity to deliver procedures and conditions of communicative competence. To assist the process of development for the engineering design research community the organizers of DESIGN 2008 propsed seven core areas for the conference as described below. It was required explicitly from all contributors to show how they are contributing to the overall area to emerge communities...
