This paper describes the development of an innovative introductory manufacturing processes course designed to expose students to a broad overview of fundamental concepts, methods, procedures, tools, and equipment used in the manufacturing industry. Based on an educational mobile inverted pendulum robot, students are introduced to product design and prototyping by identifying an existing problem with a component in the robot, redesigning the component using computer aided design software, and then building a prototype using additive manufacturing methods. Subsequently, a set of hypothetical design requirement changes is imposed, and various design methods and manufacturing processes that can be used to make components to satisfy these new requirements are discussed. Topics covered include integrated product design, additive manufacturing prototyping based on different technologies, plastic injection molding, sand casting, and fundamentals of both computer aided manufacturing and computer numerical control machining. Tools, fixtures, and accessories required in these processes, as well as associated challenges, are also discussed. This course adapts the inquiry-based learning active learning pedagogical approach and focuses on the development of students’ ability to conduct analytical analysis and to apply a knowledge of mathematics, science, engineering, and technology to solve practical engineering technology problems. As an introductory course designed to be offered to freshman level students, this course engages students in engineering technology related topics and stimulates their interest in manufacturing related subjects. It helps with improving the engineering student retention rate and serves as a pathway connecting students to more advanced specialized manufacturing courses such as computer numerical control machining technology. This paper presents course materials developed and student feedback as well as their evaluation of the course effectiveness based on a summative questionnaire-style survey from the first cohort of students.

Physical Interactions

Previously in this forum, we validated a product modularity measure and modular product design method and developed a way to extend these product modularity fundamentals to encompass the impacts of assembly process similarity and dependency. This paper expands the life-cycle process-based modularity representation to the manufacturing process and beyond. Modularity representation, including similarity and dependency, is an important aspect of modular product design and it is imperative for realizing the promised cost savings of modularity. The component-component similarity matrix is used to cluster components with similar manufacturing processes into one module. Similarities are based on component processing codes that represent their manufacturing attributes. Clustering these manufacturing process similarities leads to cost savings through module-wide sharing of process plans, manufacturing tools, and equipment, and the reduction of manufacturing tool and equipment changes during manufacturing. The component-component dependency matrix is based on physical interactions among the components that affect the material, shape, size, surface finish etc. of the components, and therefore affect the component manufacturing processes. If components are independent of other components not in the same module with respect to these physical interactions, the redesign of components in one module will not cause a cascade of design and manufacturing process plan changes for components not in the same module. A fishing reel example is used to illustrate the application of manufacturing process similarity and dependency representations, in association with a product modularity measure and a modular product design method, to form manufacturing process-based component modules. The work in this paper establishes how to represent manufacturing process similarity and dependency for use in product modularity decision making. The use of such modules improves the efficiency of manufacturing process planning, and reduces design and manufacturing process costs.

Collaborative Product Design

Manufacturing companies often face a harsh problem caused by misunderstanding between engineering and manufacturing departments. Based on different perspectives, they both strive to achieve some goals without fully evaluating the impacts of their decisions. Ambiguity in the description of responsibilities, interactions and processes makes collaborative product design and manufacturing very difficult to address. This paper presents a comprehensive overview of collaborative workflow technology which is made up of three major parts, workflow, software agents and Web services. We propose to use collaborative workflow technologies to facilitate heterogeneous processes of product design and manufacturing processes.

Design And Manufacturing

AbstractOne of the foundations of product design is the division between production and design. This division manifests as designers aspiring to create fixed iconic archetypes and production replicates endlessly in thousands or millions. Today innovation and technological change are challenging this idea of product design and manufacturing. The evolution of Rapid Prototyping into Additive Manufacturing (AM), is challenging the notion of mass manufacture and consumer value. As AM advances in capability and capacity, the ability to economically manufacture products in low numbers with high degrees of personalisation poses questions of the accepted product development process. Removing the need for dedicated expensive tooling also eliminates the cyclical timescales and commitment to fixed designs that investment in tooling demands. The ability to alter designs arbitrarily, frequently and responsively means that the traditional design process need not be applied and because of this, design processes and practice might be radically different in the future. In this paper, we explore this possible evolution by drawing parallels with principles and development models found in software development.
