“…This appropriate use cannot be guaranteed by a direct design on machining features (Dong andVijayan 1997, Wong andLeung 2000). However, it is even more important to bear in mind the representation restrictions of machining features with regard to the different perspectives inherent to CAPP (Case and Wan Harun 2000). The machining features are related to the representation of the achievable shapes by machining processes.…”

Today, the generality of computer-aided process planning (CAPP) systems and their standardization do not achieve satisfactory standards levels for industry. One of the major causes here is the difficulty of integration with computeraided design applications, due mainly to the product model used. It is therefore necessary to identify models that are general with regard to the products, but at the same time suitable for CAPP. A product model suitable for CAPP must represent the product conceptually, enabling the development of process planning functions that operate with manufacturing concepts. It is therefore necessary to develop product information models using this philosophy. The present paper focuses on this problem and proposes an information system for representing the product for internal CAPP use. It is geared towards representing all of the part information (necessary for manufacturing) integrally with the machining features and under the same concept as these features. To this end, one of the main characteristics of the model is the absence of conventional geometric entities. The application domain of the model proposed is the assignment of processes and machines in machined parts. The GF-CAPP system has revealed that the advantages of using this type of product model in CAPP are its generality with regard to the product and the ease of developing functional procedures that are general, simple and independent.

“…This involves modelling around each machining feature all of the part information which, as stated above, is the objective of the present work. The advantage in this case is the generality and simplicity of the functions for the assignment of processes, operations and machines (Zhang et al 1999, Case andWan Harun 2000).…”

“…Assembly features were traditionally used to represent geometric relations between mating parts (Shah and Rogers 1993;Anantha et al 1996;Case and Harun 2000;Chan and Tan 2003). The design intent of these features and Kim et al 2004Kim et al , 2006 the corresponding geometric relations is not explicitly specified.…”

With widely used concurrent and collaborative engineering technologies, the validity and consistency of product information become important. In order to establish the state of the art, this paper reviews emerging concurrent and collaborative engineering approaches and emphasizes on the integration of different application systems across product life cycle management (PLM) stages. It is revealed that checking product information validity is difficult for the current computer-aided systems because engineering intent is at best partially represented in product models. It is also not easy to maintain the consistency among related product models because information associations are not established. The purpose of this review is to identify and analyze research issues with respect to information integration and sharing for future concurrent and collaborative engineering. A new paradigm of research from the angle of feature unification and association for product modeling and manufacturing is subsequently proposed.Keywords Concurrent and collaborative engineering · Feature-based design and manufacturing · Product life cycle modeling · Information validity and consistency

“…It is incomprehensible to designers to model by choosing the classes of body, face, curve and topology, so application procedure interfaces (API) above these classes are developed. After encapsulating these classes, designers simply use API such as (block (0,0,0), (10,10,10)) to finish the complicated 3D models, which are shown on screen with rendering engines [26]. API is the cornerstone of modeling engines, under which is the core of a modeling system and above which are magnificent graphical interfaces.…”

“…Product functions representation based on geometric modeling including sets of objects, operations, and relations are discussed [9]. A product representation in a feature-based computer aided design and manufacture environment from detail design, process planning to assembly planning is presented, in which features are considered to be machined volumes and are described in a hierarchical taxonomy; the assembly structure is also defined hierarchically with the machining features forming the basic entities, the assembly relationships among features are defined in the form of mating relationships that are carried by the features [10]. A product representation of assembly features abstractly represented as attributes with pertinent geometrical, technological and functional data in the faces, parts and sub-assemblies is given in the automatic generation of assembly sequences [11].…”

Abstract. Evolutionary design is one kind of intelligently cooperative design, which is analogous to the evolutionary process of products. A forming method for the genome of 3D model in evolutionary design is proposed based on feature functions and topology functions. 3D model consists of features, which can respond to the environment by their functional faces and parameters, the genome which is represented by the features and their topology has been studied. The feature and topology functions are combined with geometry API in the CAD software. The genome which is symbolized as feature and topology functions is operated for the 3D model evolutionary design by genetic operators. So the genome can be taken out from the rich CAD model database to form enough scale initial population. At last, the test of phone models demonstrated the evolutionary design process including gaining their genomes automatically, evolutionary computation of their design and visualization, etc.
