“…The developed system blends the die-casting die-design rules and the industry best practices, along with the flexibility desired by a die-designer in a CAD system environment, and proves to be an effective tool in the hands of a die-designer. Development of systems for die-design for various near net-shape processes 23–31 brings the advantages of lower lead time besides reducing the effort of the die-designers. The developed system significantly reduces the time required for the design of gating system, needs little user interaction, and is very much useful for the industry.…”

The gating system design for a die-casting die is a non-trivial task that involves a number of steps and computations, in which many factors related to part design, material, and process need to be accounted. In case of a multi-cavity die-casting die, the non-triviality of the gating system design increases manifold. The main contribution of this article is to develop a computer-aided system for design of gating system for multi-cavity die-casting dies. The proposed system applies design knowledge and rules, accounting for various influencing factors to design gating system elements and generate their computer-aided design models in an efficient manner. To demonstrate the capabilities of the developed system, the results for an industrial case study part are presented. We expect that the proposed system would help reduce manufacturing cost and lead time, alongside bridging gaps between design and manufacturing of the die-casting process.

“…For most products that would benefit from modularity in design, the subsystem-level is likely the highest where it is practical to use a combination-of-functions approach. Hence the concept of feature cataloging in design [60,106], which uses a function database of options in design instead of a parts or subsystem catalog, as was often done in traditional design [107][108][109][110].…”

This work explores an additive-manufacturing-enabled combination-of-function approach for design of modular products. AM technologies allow the design and manufacturing of nearly free-form geometry, which can be used to create more complex, multi-function or multi-feature parts. The approach presented here replaces sub-assemblies within a modular product or system with more complex consolidated parts that are designed and manufactured using AM technologies. This approach can increase the reliability of systems and products by reducing the number of interfaces, as well as allowing the optimization of the more complex parts during the design. The smaller part count and the ability of users to replace or upgrade the system or product parts on-demand should reduce user risk, life-cycle costs, and prevent obsolescence for the user of many systems. This study presents a detailed review on the current state-of-the-art in modular product design in order to demonstrate the place, need and usefulness of this AM-enabled method for systems and products that could benefit from it. A detailed case study is developed and presented to illustrate the concepts.

“…The nodal degree-of-freedom based automatic assembly algorithm was developed by Ramabathiran and Gopalakrishnan [21]. The standard part library was developed to build the corresponding 3D solid model die sets automatically [22]. These studies about automatic assembly concentrated on recognizing the features to get the sizes, shapes, and positions of holes, then the parts can be assembled automatically by matching the data.…”

The die model characterized with high design efficiency and strong correlation plays an important role in simulation and machining. Because of the complexity of structure and the changing shape of flow channel, current design tools lack in the level of automation so that design of an extrusion die is a nontrivial task. In this paper, an integral design method is proposed to improve the design efficiency and model correlation. The computer-aided design (CAD) system for plastic profile extrusion die is designed and implemented by integrating Visual Studio 2010 (VS2010) and Unigraphics NX (UG). The closed loop recognition algorithm (CLR), multi closed loops intelligent recognition (MCLR) algorithm, and multi closed loops matching (MCLM) algorithm based on feature recognition are proposed to realize automatic generation of ruled surface in flow channel. The integral design and automatic generation methods of die set are proposed to facilitate efficient formation of different structures and process holes. The particle swarm optimization (PSO) algorithm is put forward to obtain best position and specification for the interference parts. Three modules (integral sketches, integral flow channel, and integral die set) are developed, which focus on integrating the proposed automation design methods into their framework. A case application on die design is used to illustrate the proposed method. The results show that the developed CAD system not only improves the design efficiency of extrusion die but also enhances the design quality.
