Paper Abstract

Freeform object design and simultaneous manufacturing is a novel virtual design and manufacturing method that aims to enable creative and individualized product geometry design and rapid manufacturing of the designed model. The geometry is defined through the process of "virtual sculpting" during which the designer can touch and visualize the designed object in a virtual environment. Natural human-computer interaction is a key issue for this method. This paper first briefly reviewed the principle of the method, including the system configuration, data flow, and fundamental algorithm. Then an input/output device was developed to achieve natural human-computer interaction. Structure of the device and algorithms of calculating the input coordinates and output force were presented. Finally a feedback model was proposed and discussed to apply force feedback during virtual sculpting design.
