Cable design and routing is a time-consuming and costly process for industrial complex products, traditionally it is finished by experienced engineers through soft lead or aluminum wire fitting in physical models, or by automatic or semi-automatic computing method in CAD system, but both with little success. In this paper, a new haptic-based interactive method is proposed. After rigid product models are loaded from CAD system, a geometry modeling method is used to represent cable shape, a physics modeling method for calculating cable deformation, and a haptic modeling method for interaction and force feedback. In this prototyping system, the user can define cable position and path, change its shape and size, and then simulate the design and routing process with haptic to feel the touch, collision and force feedback.

Abstract This paper describes the roles of features and abstraction mechanisms in the mechanical design process, mechanical designs, and product models of mechanical designs. It also describes the relationship between functions and features in mechanical design. It is our experience that many research efforts exist in the areas of design and product modeling and, further, that these efforts must be cataloged and compared. To this end, this paper culminates with the presentation of a multi-dimensional abstraction space which provides a unique framework for (a) comparing mechanical engineering design research efforts, (b) relating conceptual objects used in the life cycle of mechanical products, and (c) defining a product modeling space.

Information management for manufacturing resources such as cutting tools is an important research topic in the context of cloud manufacturing. Vendors and customers usually use catalogues to communicate information for such manufacturing resource. Incompatibilities of information in syntax, semantics, and structure among supply chains often result in inefficient manual sharing and management of the catalogue information. It is difficult for cloud based applications to pool information from various sources. This communication failure calls for a system neutral solution for data modeling and exchange to enhance interoperability of the cutting tool catalogue information. Previous studies has present solutions for representation of the cutting tool information with STEP AP242 (ISO/DIS 10303-242) with semantic classification referring to a PLib (ISO 13584, Part Library) based dictionary. This approach can be extended for the catalogue modeling, due to functionalities for specification and configuration control of general product variants in the same standard. With a modeling approach with standardized information schemas, system architecture to guide implementation is proposed to enhance the communication in practice. Relative elements to represent vendors’ catalogues and customers’ requirements are modeled. Associations to the PLib-based dictionary complete semantics and enable information mapping between vendors and customers. Principles of the mapping are identified to facilitate implementation of related software systems. Prototypes are developed to verify the proposed system architecture. The proposed solution is promising to migrate to other types of products than cutting tools, because the data models are based on the general product models defined in AP242.

The paper presents the results of studying the possibility of using the selective laser melting method for production of permanent magnets. This process allows to manufacture not only product models and prototypes, but also finished functional products by adding material layer by layer and bonding particles and layers to each other. We have considered the application areas of selective laser melting (SLM) based on powders obtained by different methods for the study. In addition, we have analyzed the traditional magnetic alloy casting technology, studied magnetic materials, and compared the powder magnet properties with standard data. We have found that the parameters of powders obtained by gas atomization are qualitatively superior to those of powders obtained using other methods, whereas the resulting magnets meet the requirements for magnets. Based on the 25Kh15KA alloy powder atomized by gas atomization, a SLM plant allows to manufacture permanent magnets with a material density of 7.59–7.55 g/cu.cm, which meets the requirements recommended by the State Standard GOST 24897-81, and to obtain the magnet properties that can be achieved using traditional metallurgical technologies.
