WAN HARUN, W.A.R. and CASE, K., 1999. A feature-based representation of process planning and assembly knowledge for concurrent engineering applications. Journal of Industrial Technology, 18 (2), pp. 19 - 30
The need for a product model which can support the modelling
requirements of a broad range of applications leads to the use of feature-based
techniques. An important requirement in feature-based design and manufacture is that a
single feature representation should be capable of supporting a number of different
applications. Assembly and process planning are seen as two crucial applications and a
formal structure for their representation in a feature-based design system is presented.
This paper addresses two basic questions relating to the lack of a unified definition
for features and the problem of representing assemblies in a feature-based
representation. A prototype system has been implemented using object-oriented
techniques which provide a natural method of adding functionality to the geometric
reasoning process of features and the complex relationships between the parts that
make up the assembly.
