Book Description
Cost reduction and increasing production rates are driving automation of aerospace manufacturing. Articulated serial robots may replace bespoke gantry automation or human operations. Improved accuracy is key to enabling operations such as machining, additive manufacturing (AM), composite fabrication, drilling, automated program development, and inspection. New accuracy standards are needed to enable process-relevant comparisons between robotic systems. Accuracy can be improved through calibration of kinematic and joint stiffness parameters, joint output encoders, adaptive control that compensates for thermal expansion, and feedforward control that compensates for hysteresis and external loads. The impact of datuming could also be significantly reduced through modeling and optimization. Highly dynamic end effectors compensate high-frequency disturbances using inertial sensors and reaction masses. Global measurement feedback is a high-accuracy turnkey solution, but it is costly and has limited capability to compensate dynamic errors. Local measurement feedback is a mature, affordable, and highly accurate technology where the robot is required to position or align relative to some local feature. Locally clamped machine tools are an alternative approach that can utilize the flexibility of industrial robots while also enabling high-quality machined surfaces. Hybrid high-accuracy control strategies will be required for many processes.

Book Description
Is human-robot collaboration the future for aerospace manufacturing? It is widely acknowledged that the application of robotics and automation in aerospace manufacturing is significantly lower than might be expected given the size and value of the industry and its technologically advanced products. When deployed, it tends to be either in relatively simple activities, such as machine loading and handling, or in the form of large bespoke systems for processes such as fastening. The reason for this is multifactorial but includes product variability, size, design philosophy, and relatively low volumes. Also, there is occasional reticence due to a history of past false starts. that increase the perceived risk associated with the introduction of new technologies. Current thinking suggests that the emerging technology of human-robot collaboration provides an ideal solution, combining the flexibility and skill of human operators with the precision, repeatability, and reliability of robots. However, this is a topic that tends to generate emotional and emotive reactions within the industry ranging in extremes from a brave new and inevitable future for aircraft manufacturing and assembly, to workers living in fear of a robot invasion and lost jobs. In this SAE EDGE Research Report we seek to build a comprehensive picture of the current state-of-the-art of human-robot applications and identify key issues that unlock the technology's potential. We have sought the views of recognised thought leaders to understand and deconstruct the myths and realities of human- robot collaboration, and how it could eventually have the impact envisaged by many.

Book Description
The aerospace manufacturing industry is, in many ways, one of the most sophisticated commercial manufacturing systems in existence. It uses cutting-edge materials to build highly complex, safety-critical structures and parts. However, it still relies largely upon human skill and dexterity during assembly. There are increasing efforts to introduce automation, but uptake is still relatively low. Why is this and what needs to be done? Some may point to part size or the need for accuracy. However, as with any complex issue, the problems are multifactorial. There are no right or wrong answers to the automation conundrum and indeed there are many contradictions and unsettled aspects still to be resolved. Unsettled Issues on the Viability and Cost-Effectiveness of Automation in Aerospace Manufacturing builds a comprehensive picture of industry views and attitudes backed by technical analysis to answer some of the most pressing questions facing robotic aerospace manufacturing.

Unsettled Technology Domains for Rapid and Automated Verification of Industry 4.0 Machine Tools

Book Description
Currently, inaccuracies in machine tools are often not detected until after they have produced nonconforming parts, causing reworking or scrap. For high-value aerospace parts, a single rejected part is a significant cost. Low-value parts are often inspected less frequently, allowing many nonconforming parts to be produced before the issue is detected, also resulting in high cost. The alternative to relying on part inspection is to run frequent tests on the machine itself, but established calibration and health-check processes take between 20 minutes and several days. Emerging rapid and automated verification (RAV) processes enable machine tools to check their performance automatically in just a few minutes. These RAV processes can be performed frequently throughout the day, allowing machines to operate without human intervention for long periods of time. When an issue is detected, the machine may be able to recalibrate and then continue automatically. Where this is not possible, the machine stops and provides diagnostic information enabling the operator to efficiently get the machine back into production. For many machines, especially smaller ones, artifact probing is the most cost-effective and easily implemented method. Combined with probing of roughing cuts, it can also verify spindle and dynamic errors at the micrometer level. Inertial measurement has a lot of potential to provide continuous monitoring during operations, and significant research efforts are therefore justified to validate and improve diagnostic capability. Noncontact triple-probing of spheres can provide highly accurate RAV while also enabling some compensation to be achieved in a very rapid way. This equipment is costly when dedicated to each machine for RAV but may be justified for very high-value machines and processes.

Book Description
Air Force support of a Center of Excellence at Stanford University has provided the impetus and core for a major new entity, the Center for Automation and Manufacturing Science (CAMS). The new center draws from two well-known research groups at Stanford: the Robotics Group of Stanford's Artificial Intelligence Laboratory and the Automatic Control Group of Stanford's Department of Aeronautics and Astronautics. Ten professors and some 50 graduate students are participating in CAMS activities. CAMS in turn is the first of a new complex of centers at Stanford involved in the manufacturing enterprise: the Stanford Institute for Manufacturing and Automation (SIMA). Strong industrial interaction is a primary objective of SIMA. In our Air Force program we are focusing on robotic aspects of automation. Our goal is to make fundamental contributions to the underlying set of technologies that will enable the next generation of industrial robots to be far more capable than today's - will enable them to be lightweight, limber, deft, facile, quick, friendly, low-powered, seeing, sensing, thinking machines that can reason and strategize- can carry out tasks assigned at a high conceptual level. Specifically, our research focus is on fast, precise control of lightweight (flexible) manipulators, sensing, especially optical and tactile sensing, intelligent systems for robot task management, and computer vision for robot management. We are addressing the question of how to provide manipulator control so good that a whole new generation of manipulators can be developed-manipulators that are much lighter and far more facile than anything today's control systems could stably manage.

Book Description
In its entirety, automation is part of an integrated, multi-disciplinary product development process including the design, process, production, logistics, and systems approach—it depends on all these areas, but it also influences them as well. Automation in aerospace manufacturing is present throughout the entire supply chain, from elementary part manufacturing at suppliers up to final assembly, and a clear understanding of all the benefits (and drawbacks) of automation would help designers and engineers select the right designs for and levels of automation. The Right Level of Automation Within Industry 4.0 examines all impacts of automation that should be known by designers, manufacturers, and companies before investments in automation-related decisions are made—regardless of the which industry they work in. The process and the set of criteria discussed in this report will help decision makers select the right level of automation.

Book Description
“Smart” refers to tools that are “specific, measurable, achievable, reasonable/realistic, and time bound.” Smart assembly tools are used in many industries, including automotive, aerospace, and space for measuring, inspecting, gauging, drilling, and installing all existing fastening systems. Inside the Industry 4.0 environment, these tools have a huge influence on Information and Communication Technology (ICT), assembly cost reduction, process control, and even the product and process quality. These four domains—and their undefined nature—are the focus of this SAE EDGE™ Research Report. The technical issues identified here need to be discussed, the goals clarifying the scope of the industry-wide need to be aligned, and the issues requiring standardization need prioritized. NOTE: SAE EDGE Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues.
