This book explores, in a systematic way, both conventional and unconventional material shaping processes with various modes of hybridization in relation to theory, modelling and industrial potential. The demand for high productivity and high accuracy in manufacturing is continuously increasing, based on improvement and optimization strategies. Hybridization of manufacturing processes will play a crucial role and will be of a key importance in achieving environmental and economical sustainability. Structured in three parts, Hybrid Manufacturing Processes summarizes the state-of-the art hybrid manufacturing processes based on available literature sources and production reports. The book begins by providing information on the physical fundamentals of the removal and non-removal processes in macro-, micro and nanoscales. It then follows with an overview of the possible ways of hybridization and the effects on the enhancement of process performance, before concluding with a summary of production outputs related to surface integrity, specifically with respect to difficult-to-machine materials. Considering the applications of different sources of hybridization including mechanical, thermal and chemical interactions or their combinations, this book will be of interest to a range of researchers and practicing engineers within the field of manufacturing.

This book focuses on the emerging additive manufacturing technology and its applications beyond state-of-the-art, fibre-reinforced thermoplastics. It also discusses the development of a hybrid, integrated process that combines additive and subtractive operations in a single-step platform, allowing CAD-to-Part production with freeform shapes using long or continuous fibre-reinforced thermoplastics. The book covers the entire value chain of this next-generation technology, from part design and materials composition to transformation stages, product evaluation, and end-of-life studies. Moreover, it addresses the following engineering issues: • Design rules for hybrid additive manufacturing; • Thermoplastic compounds for high-temperature and -strength applications; • Advanced extrusion heads and process concepts; • Hybridisation strategies; • Software ecosystems for hAM design, pre-processing, process planning, emulating and multi-axis processing; • 3D path generators for hAM based on a multi-objective optimisation algorithm that matches the recent curved adaptive slicing method with a new transversal scheme; • hAM parameters, real-time monitoring and closed-loop control; • Multiparametric nondestructive testing (NDT) tools customised for FRTP AM parts; • Sustainable manufacturing processes validated by advanced LCA/LCC models.

Automation in production of 3D printed parts, hybrid additive and subtractive machines, and post-processing of 3D printed parts are rapidly growing fields. Given the numerous advancements in the 3D printing industry as reported in this thesis, the lack of availability of a Do It Yourself (DIY) and low-cost hybrid additive and subtractive unit is identified and tackled. This thesis covers the mechanical design of a low-cost DIY, hybrid additive and subtractive unit using a robot arm to remove the 3D printing support structures. Since the removal of printed support structures has not been investigated in the scientific literature, in a first step, different cutting tools and speeds were analyzed with a hand-held Dremel 4000 power tool with regard to cut quality and cutting forces. An off-the-shelf tool bit, a High-Speed steel cutter, at 15000 rpm yielded the best results. Furthermore, a hybrid machine was conceptualized, consisting of additive and subtractive subsystems. The constraints are a working volume of 6 cubic inches and costs below $5000. The additive system is based on following components: X, Y and Z Motor Holders, Filament Holder, and 3D Printing Arm, which can be printed by the DIY user, and off-the-shelf hardware like NEMA 17 stepper motors. The subtractive system is based on the following components: Motor Holder, Linkbot Mounting Interface, and Connector Arm, which are also designed to be 3D printed by the DIY users. For both subsystems, the off-the-shelf parts are specified, and technical drawings for 3D printing and assembly are provided. The critical 3D printed parts are analyzed with regard to their maximum distortion and strength during operation.

It is always hard to set manufacturing systems to produce large quantities of standardized parts. Controlling these mass production lines needs deep knowledge, hard experience, and the required related tools as well. The use of modern methods and techniques to produce a large quantity of products within productive manufacturing processes provides improvements in manufacturing costs and product quality. In order to serve these purposes, this book aims to reflect on the advanced manufacturing systems of different alloys in production with related components and automation technologies. Additionally, it focuses on mass production processes designed according to Industry 4.0 considering different kinds of quality and improvement works in mass production systems for high productive and sustainable manufacturing. This book may be interesting to researchers, industrial employees, or any other partners who work for better quality manufacturing at any stage of the mass production processes.

Hybrid Additive Manufacturing: Techniques, Applications and Benefits explains the fundamentals of hybrid AM, definitions, classifications, and principles, as well as key techniques of hybrid AM, its applications, design guidelines, and benefits, with emphasis on key aspects of the system integration process. The core of this subject is in describing how to overcome inherent processing limitations of layer-by-layer AM through the integration of secondary post-processing such as machining or heat treatment. As a result hybrid AM plays a critical role in accelerating the adoption of AM in established design and manufacturing activities. The applications of hybrid AM in both metals and polymers are discussed in this book, as are geometrical dimensioning and tolerancing, material property enhancement, non-traditional surface finishing, in-situ sequential hybrid processing, and integrated process planning. This book will serve not only as an introduction to hybrid AM but also as a handbook for researchers and engineers in mechanical, manufacturing, industrial, electronics, and materials science, thanks to its interdisciplinary approach and detailed case studies. Explains how hybrid manufacturing processes can be used to achieve enhanced material properties and functionality Describes the significance of hybrid additive manufacturing to different parts of the process chain Uses case studies to show how innovative companies are using this technology, how they have overcome challenges they encountered, and the benefits they have experienced
