Prototype Development

Advanced application of powerful computer tools at engineering design of advanced products related activities means creating integrated product models in advanced computer systems. Leading application oriented master model concepts and standards as STEP serve this purpose. Engineers are working simultaneously on product design. Results of engineering decisions are analyzed for loads, aesthetics and manufacturability. Product design, results of analyses, processes of manufacturing of parts and much more are described in integrated product model. This model is accessed by several engineers simultaneously and is communicated with other engineering design environments. Because most of prototype development activities are being moved into computer systems, advanced modeling is often cited as virtual pro-, totyping. This paper summarizes and relates some advanced modeling approaches and methods to emphasize main trends in fulfilling demands for modeling tools in the early 21th century. As one of the key issues a manufacturing process model associative with form feature based part model is introduced. This model was proposed by the authors. The motivation is that low level integration of design and manufacturing of mechanical parts is still a main drawback of efficient application of expensive modeling systems. The proposed method ’allows for creating part models simultaneously with their analysis of machineability. In this paper chapter 2 outlines the scene of modeling based decision making of engineers as well as levels of product model creation. Chapter 3 explains the prevailing modeling principles, while chapter 4 emphasizes structure descriptions. In chapter 5 the proposed associative, Petri net model representation based manufacturing process modeling and its potential applications are explained are detailed. Two additional key subject areas are discussed in chapter 6 and chapter 7, namely effects of globalization on modeling and product data management. The main aspect of discussion is model and communication based group work of engineers.

This paper presents a novel methodology for modeling manufacturing processes of mechanical parts. The aim was to develop a manufacturing process model that describes all possible process variants in a single model and involves generic process description for a cluster of manufacturing tasks. It must be fit into the product model concept. A four-level generic manufacturing process model has been developed by using Petri net representation for model entities. Advanced shape models do not describe the intent of the designer and other information that is necessary for the application of the model. As a contribution to solving this problem, we propose a methodology for attaching designer intent information and knowledge to geometric and form feature models. This improves communication between the product designer and production engineer. First, the importance of the manufacturing process model and its interconnections with other product related models are emphasized. Then, the structure, entities, creating, evaluation, and application of the manufacturing process model are explained. Next, product and production process modeling procedures are analyzed from the point of view of design intent information to be transferred between product designers and manufacturing engineers. Finally, characteristics of communication between engineers and modeling of human intent are outlined.

Robust Engineering Design

A fundamental idea has emerged from the study of the work of Genichi Taguchi in off-line quality control. A product should be designed so that it is robust against variations in the manufacturing process and the environment in which it is used. But the idea is not entirely new. It appears in various forms in the vogues and syntax of modern engineering design. Thus we have ‘design to product’, ‘design for manufacture’, ‘conceptual design and innovation’, ‘systematic methodologies’ and so forth. It is the ability to describe robustness in statistical terms that ought to create a change in design thinking. But for this to happen professionals on both sides need to understand each other’s language. The paper attempts to bridge the gap by drawing heavily on the language of engineering design and giving recent examples of product design where both modes of thinking have benefited from each other.

With the more profound requirements for knowledge resource application in the complex production collaborative design, a complex production design method based on knowledge model driven was put forward with the development trend of intelligent design theory. The knowledge mining oriented the key phases of complex production design process, knowledge modeling with its reuse are the core of the method. The system framework of the design method was structured. This method supports the whole process of product design, it truly realized sharing, reuse and seamless integration among product model, task model and process model through the ontology model as a knowledge carrier. Finally, the thrust bearing-a key component of hydropower generating units, for example verify the correctness of the design methodology and feasibility.

Design Experience

All Engineering Science students at the University of Toronto take the cornerstone Praxis Sequence of engineering design courses. In the first course in the sequence, Praxis I, students practice three types of engineering design across three distinct design projects. Previously the final design project had the students first frame and then develop conceptual design solutions for a self-identified challenge. While this project succeeded in providing an appropriate foundational design experience, it failed to fully prepare students for the more complex design experience in Praxis II. The project also failed to ingrain the need for clear and concise engineering communication, and the students’ lack of understanding of detail design inhibited their ability to make practical and realistic design decisions. A revised Product Design project in Praxis I was designed with the primary aims of: (a) pushing students beyond the conceptual design phase of the design process, and (b) simulating a real-world work environment by: (i) increasing the interdependence between student teams and (ii) increasing the students’ perceived value of engineering communication.

Background: In the whole design process of modular fuel tank, there are some unreasonable phenomena. As a result, there are some defects in the design of modular fuel tank, and the function does not meet the requirements in advance. This paper studies this problem. Objective: Through on-the-spot investigation of the factory, a mechanical design process model is designed. The model can provide reference for product design participants on product design time and design quality, and can effectively solve the problem of low product design quality caused by unreasonable product design time arrangement. Methods: After sorting out the data from the factory investigation, computer software is used to program, simulate the information input of mechanical design process, and the final reference value is got. Results: This mechanical design process model is used to guide the design and production of a new project, nearly 3 months ahead of the original project completion time. Conclusion: This mechanical design process model can effectively guide the product design process, which is of great significance to the whole mechanical design field.

Interactive Relationship

Fixtures, tools, and other assembly resources have an important role in the assembly of complex products, so it is very necessary to consider the interactive relationship between the resources model and the product model for assembly order planning in 3D environment. Firstly, the features of assembly process planning involved resources are analyzed. Secondly, the concept of the assembly process intention（AsmPI） is introduced，and an assembly process can be divided into an AsmPI sequence. Thirdly, based on the graph theory, a resource-involved assembly process model is built up. At last, setting a typical structure as an example, the validity of this modeling method is verified.

In this paper, we advocate for a more harmonized approach to model development for additive manufacturing (AM) processes, through classification and metamodeling that will support AM process model composability, reusability, and integration. We review several types of AM process models and use the direct metal powder bed fusion AM process to provide illustrative examples of the proposed classification and metamodel approach. We describe how a coordinated approach can be used to extend modeling capabilities by promoting model composability. As part of future work, a framework is envisioned to realize a more coherent strategy for model development and deployment.
