Designing a Modular Rapid Manufacturing Process
Journal of Manufacturing Science and Engineering-transactions of The Asme, 2010Co-Authors: Jacquelyn K. S. Nagel, Frank W. LiouAbstract:Freeform fabrication and additive fabrication technologies have been combined with subtractive Processes to achieve a variety of fully integrated rapid Manufacturing systems. The combination of separate fabrication techniques into one rapid Manufacturing system results in unit Manufacturing Process integration, sometimes known as a hybrid system. However, the design methods or approaches required to construct these integrated systems are vaguely described or not mentioned at all. The final product from any integrated system is affected not only by the unit Manufacturing Processes themselves, but also by the extent the individual units are assimilated into an integrated Process. A wide variety of integrated and hybrid Manufacturing systems and current Manufacturing design methodologies are described in this paper, along with their similarities and differences. Through our extensive review, it was discovered that there are five key elements to a reliable integrated rapid Manufacturing system: Process planning software, motion system, control system, unit Manufacturing Process, and a finishing Process. By studying the manner in which all other systems have been integrated, a table of successful integrated Manufacturing system element combinations has been complied, documenting each of the key element choices, resulting in a variety of modular designs. This paper further discusses the importance of the five elements in Manufacturing system integration, and how an integrated system is the way to move forward in the Manufacturing domain. To that end, a rapid Manufacturing system design methodology was developed that explores designs via Process analysis to discover integration potential. Cost-benefit analysis is then used to assess the performance of the new system. This analysis determines if all needs have been met, while staying within the constraints of time and resources. Additionally, a table of common issues and obstacles encountered during Manufacturing system development has been compiled to assist in the design and development of future rapid Manufacturing systems. To illustrate the design methodology, our modular design experience with a laser aided Manufacturing Process is presented. Unit Manufacturing Process integration has increased the productivity and capabilities of our system, which reduced resource volume and increased productivity.

Manufacturing Process information modeling using a metamodeling approach
The International Journal of Advanced Manufacturing Technology, 2018Co-Authors: Bin Yang, Lihong Qiao, Zuowei Zhu, Na Cai, Muqi WulanAbstract:Information integration and interoperability among different design and Manufacturing application software systems are important in smart Manufacturing implementation and product life cycle management. Information models are foundational and critical to the specification of common terms, interfaces, and software architectures for information interoperability. The Manufacturing Process is one of the key Processes in a product life cycle. This paper presents a methodology of using the metamodels as the modeling basis in Manufacturing Process information modeling. A Manufacturing Process information metamodel (MPIMM), which consists of object classes, relationship classes, and relationships, defines the information and relationships of Processes, operations, resources used, and product/part manufactured of Manufacturing Process planning. The MPIMM is built by unified modeling language (UML) while the semantics of the Process elements and their attributes are specified referencing the Process specification language. A four-layer framework is proposed to construct Manufacturing Process information model (MPIM) following the rules of metamodeling, and including meta-metamodeling, Manufacturing Process information metamodeling, and Manufacturing Process domain information modeling; thus, Manufacturing Process plan data can be represented. The UML profile extension mechanism realized by defining Stereotype, TaggedValue, and Constraint is used in extending MPIMM to MPIM. A case study of applying MPIM in the product life cycle data management system for port hoisting equipment Manufacturing is provided to demonstrate and verify the modeling capability and efficiency of the proposed methodology. This work provides a systematic and standardized modeling methodology and information expression mechanism for Manufacturing Process information.

A Metamodel for the Manufacturing Process Information Modeling
Procedia CIRP, 2016Co-Authors: Bin Yang, Lihong Qiao, Zuowei Zhu, Muqi WulanAbstract:Abstract Since the Manufacturing Process information and their mutual relationship are complex and diverse, the clear and accurate description and modeling of Manufacturing Process information is a challenge in related study of Manufacturing Process. Considering the diversity of the Process data, a four-layer framework for Manufacturing Process information modeling based on metamodel is proposed. A 4-tuple Manufacturing Process information metamodel is specified and the concepts and relationships of the Manufacturing Process information are represented by UML. Following the four-layer hierarchical modeling procedures in the framework, Manufacturing Process information can be modeled from metamodel to model in consistence with their data relationships and representations. An instance of information model regarding to machining Process is developed for verification. This work provides a systematic and standardized modeling method and information expression mechanism for Manufacturing Process information modeling.

Manufacturing Process modelling using Process specification language
The International Journal of Advanced Manufacturing Technology, 2011Co-Authors: Lihong Qiao, Shuting Kao, Yizhu ZhangAbstract:The Manufacturing Process is one of the important Processes in a product’s life cycle. The sharing of Manufacturing Process information among different functional application systems, such as Process planning, Manufacturing simulation, Manufacturing execution and project management, has become difficult to implement due to the growing complexity of the Manufacturing information of product, Process, resource and plant. A unified representation of Manufacturing Process information for all applications can enable convenient integration between different application systems. The development of Manufacturing-related ontology and the Process Specification Language (PSL) has provided a formal definition and structure of semantic concepts for the capture and the exchange of Manufacturing information. This paper presents a Manufacturing Process information modelling method which builds a standard, complete and exact definition of Manufacturing Process data by applying current PSL specifications. New extensions of the concepts of the Manufacturing Process and the types of relationship for describing activities, materials and resources in a Process are identified and developed. The completeness and adaptability of activity relation of the proposed Manufacturing Process information representation is verified using mathematical induction under a variety of complex Manufacturing Process situations. The ability of the modelling method in expressing complex Process information is demonstrated by a machining Process example.

Ontologies for Manufacturing Process Modeling: A Survey
Sustainable Design and Manufacturing 2018, 2019Co-Authors: Qiushi Cao, Cecilia Zanni-merk, Christoph ReichAbstract:Within the product life cycle, Manufacturing Processes are steps through which raw materials are assembled and transformed into final products. When different applications share information concerning Manufacturing Processes, the lack of information interoperability is a challenging issue that emerges during the Manufacturing Process implementation phase. The interoperability issue has brought resistance to Manufacturing systems for pursuing desired flexibility. To solve this problem, semantic technologies, especially ontologies have shown promising results. This survey paper examines the existing ontologies that are developed to cope with Manufacturing Process modeling. By categorizing these ontologies into three dimensions, we aim to specify how ontologies help to enhance the information interoperability among different Manufacturing systems, applications and stakeholders. The results of this paper could be used as a suitable reference for developing new ontologies which aim at improving decision support in sustainable Manufacturing.
