Abstract
In order to shorten design lead time, recent manufacturers usually employ diversion design by using a knowledge base CAD system. In diversion design, a CAD data should be constructed by an appropriate modeling procedure in order to respond to a future diversion. However, especially a novice CAD operator hardly thinks about a modeling procedure for diversion. Therefore, it takes much time for an operator to understand a modeling procedure of CAD data which is constructed by the other, and then design lead time cannot be shortened as much as expected. We have been developing a modeling procedure document creation system, called C3 (Cubic), which supports a CAD operator to understand the modeling procedure in a short time. By applying this system, we implemented "ONT (On the Network CAD Training) system" by which an operator can efficiently learn the modeling procedure online. The ONT system was experimentally operated for verification. As a result, the efficiency of diversion design has improved by approximately 3 times that of former technique.
