Up until the last two decades, aluminum in airplanes and steel in automobiles were the primary materials used to produce these two complex machines. These metal-to-metal assemblies, and specifically the same-type metal-to-metal assemblies, have resulted in distinct manufacturing process advantages over decades of production. However, advances in material types have driven manufacturing to adapt and align the fabrication and assembly processes to continue to facilitate a quality product that is reliable, can be manufactured at a price point that is affordable and be manufactured in quantities that can be widely distributed. Dissimilar metal and composite material assemblies are now requiring highly complex manufacturing processes. Innovations in Automotive and Aerospace Assembly addresses how these new, disruptive materials usage are changing the manufacturing and production processes for the transportation industries. Highlights and features in the book include: Non-contact laser technology's transition into aerospace use Emerging thickness and hole measurement gauge technologies Non-destructive adhesive inspection techniques The goal is to provide the latest technologies and methodologies being introduced into automobile and aerospace manufacturing - appealing to materials, manufacturing and design engineers alike.

The evolution and execution of automotive manufacturing are explored in this fundamental manual. It is an excellent reference for entry level manufacturing engineers and also serves as a training guide for nonmanufacturing professionals. The book covers the major areas of vehicle assembly manufacturing and addresses common approaches and procedures of the development process. Having held positions as both a University Professor and as a Lead Engineering Specialist in industry, the author draws on his experience in both theory and application to fill the gap between academic research and industrial practices. This concisely written, comprehensive review discusses the sophisticated principles and concepts of automotive manufacturing from development to applications and includes: 250 illustrations and 90 tables. End-of-chapter review questions. Research topics for in-depth case studies, literature reviews, and/or course projects. Analytical problems for additional practice. Directly extracted and summarized from automotive manufacturing practices, this book serves as an essential manual. The subject is complemented by the author’s first book, Automotive Vehicle Assembly Processes and Operations Management, which provides even greater depth to the complex endeavor of modern automotive manufacturing.

It is ironic that as aircraft have gotten more sophisticated, much of their manufacture has remained manual. However, as orders for commercial aircraft have dramatically increased over the past years and are expected to remain on that trajectory, the competition has become not just about how fast new technologies can be put on the aircraft, but about how fast the aircraft can be manufactured and delivered. Enter ever increasing automation and robotics. Just as it has taken multiple years to reach the sophisticated content levels on current generation aircraft, so too has it been necessary to continually learn new ways and means to increase automation on the manufacturing floor. For both aircraft on the flight line and on the production line, safety is paramount. This book will look at a variety of topics that range from the risks and rewards of increased cooperation between humans and robots within manufacturing systems, to introducing a process that enables the determination of whether the robot or the human gets assigned a particular task, to the configuration and optimization of flexible assembly cells, all with the end goal of safely reducing time-to-market and production costs.

Abstract: Bonded composite-metal assemblies present an interesting challenge to fixturing technology as it exists in its current form. Fixturing such an assembly has not yet been studied in depth. In particular, the aerospace industry, a common consumer of such technology, requires rethinking of the current status quo in design for assembly and fixturing techniques to improve accuracy, reduce assembly time and reduce fixturing and part assembly cost. This is especially true for the assembly of Unmanned Aerial Vehicles, or UAVs, which make use of this technology. In this thesis, several key technologies are investigated which have the potential to improve fixturing of composite-bonded assemblies. Kinematic constraint and fixturing serve to improve the accuracy of alignment by reducing the degree to which parts are overconstrained. This results in less induced stress and less potential for misalignment of parts in the fixture. Software that has been developed by Bozzo, Rush and Stephens is used to analyze both existing fixturing and redesigned fixturing setups. Flexible fixturing technologies have the potential to reduce prototype and small production run assembly time by reducing fixturing production time as well as accommodating various design changes common to prototype situations. While many such systems are already in existence, a selection of custom holding devices can be produced work in concert with the flexible fixturing systems already available. These features should be created with a product family design in mind, so future assemblies can reuse custom-made holding devices. Some of these technologies are then used to create a flexible fixturing conceptual design, which would be a replacement to the fixturing used in a subassembly of a composite-bonded UAV body. This fixturing is modeled using tolerance chains to determine the degree of accuracy expected. A subset of this fixturing is then assembled and tested to determine the actual accuracy that can be expected, as well as the repeatability and time savings over the original fixturing.
