Design for Manufacturing and Assembly Principles and Methods
Learning Objectives
In this section we will discuss the general principles of design for manufacturability and design for assembly. Also critical to achieving quality functional products is proper dimensions and tolerancing of parts. Therefore, this section also covers basics of geometric dimensions and tolerancing as well as the specification of fits. In short, how to design parts so that they can be manufactured and assembled to work well with an acceptable level of quality. After completing this section, reader should be able to:
- Define what DFMA is and why it is important for the design process.
- Apply DFMA principles and practices in different domains and contexts.
- Describe methods and tools are available for DFMA analysis and evaluation.
- Apply principles to measure and improve the performance of a product or system using DFMA metrics and criteria.
- Understand and use standard GD&T symbols in part drawings.
- Specify a desired size and tolerance for a fit using standard tables.
Design for manufacturability and assembly (DFMA) is a set of principles and practices that aim to optimize the design of a product or system for its efficient and effective production and integration. DFMA is an important part of the design process because it can reduce the cost, time, complexity, and environmental impact of manufacturing and assembling a product or system. DFMA can also improve the quality, reliability, performance, and customer satisfaction of the final product or system. In this chapter, we will introduce the concepts and benefits of DFMA, as well as the methods and tools for applying it in different domains and contexts.
Follow along with Professor Cummings’ introductory lecture to understand the context of DFMA.
