FIGURE 1.16 An illustration of the different faces of the parts in the test-case assembly. 1.6 Discussion and Conclusions A comprehensive understanding of different issues involved in the application of ICAD techniques for the development of an IPD system has been discussed in this chapter. A fundamental understanding of these issues is the key toward the development of intelligent and integrated design systems with enhanced capabilities for product design. The development of prototype product design systems for design analysis, process planning, and tolerance assignment has also been reported in this chapter. © 2001 by CRC Press LLC Concept Modeller AGM Components of ASSEMBLY ASSEMBLY Cavalier View Z Y X PART-1 PART-2 PART-3 BASE-FEATL NEGATIVE-F BASE-FEATL POSITIVE-FE
