“…It can be employed to describe assembly or mating relations between assembled parts in CAD assembly model. Assembly feature pair (AFP): a pair of assembly features on two different assembled parts interacting with each other when the two parts taking part in assembly activity (Xu et al, 2013;Zhang et al, 2015). For mechanical assembly, the connection relationships could be divided into soft connection and hard connection according to the mating and fastening operations.…”

PurposeThree-dimensional computer-aided design (CAD) assembly model has become important resource for design reuse in enterprises, which implicates plenty of design intent, assembly intent, design experience knowledge and functional structures. To acquire quickly CAD assembly models associated with specific functions by using product function requirement information in the product conceptual design phase for model reuse, this paper aims to find an approach for structure-function correlations analysis and functional semantic annotation of mechanical CAD assembly model before functional semantic-based assembly retrieval.Design/methodology/approachAn approach for structure-function correlations analysis and functional semantic annotation of CAD assembly model is proposed. First, the product knowledge model is constructed based on ontology including design knowledge and function knowledge. Then, CAD assembly model is represented by part attributed adjacency graph and partitioned into multiple functional regions. Assembly region and flow-activity region are defined for structure-function correlations analysis of CAD assembly model. Meanwhile, the extraction process of assembly region and flow-activity region is given in detail. Furthermore, structure-function correlations analysis and functional semantic annotation are achieved by considering comprehensively assembly structure and assembled part shape structure in CAD assembly model. After that, a structure-function relation model is established based on polychromatic sets for expressing explicitly and formally relationships between functional structures, assembled parts and functional semantics.FindingsThe correlation between structure and function is analyzed effectively, and functional semantics corresponding to structures in CAD assembly model are labeled. Additionally, the relationships between functional structures, assembled parts and functional semantics can be described explicitly and formally.Practical implicationsThe approach can be used to help designers accomplish functional semantic annotation of CAD assembly models in model repository, which provides support for functional semantic-based CAD assembly retrieval in the product conceptual design phase. These assembly models can be reused for product structure design and assembly process design.Originality/valueThe paper proposes a novel approach for structure-function correlations analysis and functional semantic annotation of mechanical CAD assembly model. Functional structures in assembly model are extracted and analyzed from the point of view of assembly structure and function part structure. Furthermore, the correlation relation between structures, assembled parts and functional semantics is expressed explicitly and formally based on polychromatic sets.

“…An assembly port is defined to be a group of one or more low-level geometric entities, such as faces, edges, or centerlines, that undergo mating constraints in order to join parts in a CAD assembly. In [29,30], the authors propose a framework method to integrate assembly modeling and simulation based on Assembly Feature Pairs. An Assembly Feature Pair consists of form-feature pairs containing information on assembly behaviors.…”

When it comes to Engineering-To-Order (ETO) products, neither the exact number nor the form of the components in them can be predefined. Thus, existing assembly models and generative design techniques are not adequate to support development of design automation tools for ETO products. ETO companies usually use custom libraries with past case designs that are adjusted to a customer's requirements. This method is not cost effective and it is prone to human errors. In this work, we present the Automatic Assembly Synthesis Model (AASM), connecting a Knowledge Based Engineering (KBE) system and a CAD system to automate routine design tasks for ETO mechanical products.

“…In addition, an automatic assembly method was applied in a robotic assembly system for automatic programming of new assembly tasks (Wang et al , 2011). A framework to integrate assembly modelling and simulation was also introduced to eliminate the errors in specifying the assembly constraints (Zhang et al , 2015b). Some applications investigated the generation of the assembly sequence, considering issues such as geometrical, mechanical and stability predicates (Bahubalendruni et al , 2015).…”

Purpose The purpose of this paper is to develop an assembly modelling approach to be applied with a software package, to assist in the design and assembly of special purpose machines (SPMs). Design/methodology/approach A database of SPM elements was established, and an assembly relationships graph was created. Mating conditions were identified between the SPM elements, and their assembly constraints were extracted and implemented in SolidWorks application programming interface. Findings The implementation of this assembly modelling approach was validated by selecting SPM layouts as examples. A significant reduction in the assembly time was achieved compared to the traditional assembly procedure for the same examples. Originality/value This is a new application of assembly modelling that assists engineers and designers in the design and assembly processes of SPMs. This approach can also be applied to other machine tools with similar attributes.
