Design of Composite Structures
Published in Manoj Kumar Buragohain, Composite Structures, 2017
Advanced manufacturing processes have greatly increased the horizon of possibilities in front of the design engineers and added immensely to the development of complex and highly efficient products. These processes, however, have their own limitations that put constraints. For successful component realization, it is important that these limitations are clearly understood and accounted for in the design process. For example, let us consider the composite manufacturing process of filament winding. No doubt, it is highly suitable for making axisymmetric components such as a cylindrical pipe, etc. and it allows automated efficient placement of impregnated fibers along the desired orientation. Helical winding, however, does not allow one to arbitrarily vary the fiber orientation along the axis of the component and the designer must keep this constraint in mind and choose fiber orientations that are windable. Another example is that of autoclave curing. It gives good consolidation and high-quality laminate. But it is not suitable for making a laminate of uniform thickness with good surface finish on both the sides. If good surface finish is required on both the sides of a uniformly thick laminate and autoclave curing is involved, then machining can be introduced and the resulting reduction in material properties due to fiber cutting may have to be accounted for in the design calculations. In other words, manufacturing feasibility and limitations should be considered during the design process and suitable corrective steps should be introduced as required.

Advanced manufacturing refers to the use of cutting-edge technologies as well as innovative planning methods with the ultimate purpose of enhancing the competitiveness of the whole supply chain by offering innovative products and services. It should be noted that advanced manufacturing does not only include advanced technologies, but it also is an integration of improved processes, advanced planning methods, innovative products, and skilled workforce.
Fundamentals of Manufacturing and Engineering
Published in Jong S. Lim, Quality Management in Engineering, 2019
Highly technological products like semiconductors, smartphones, robots, and biomedicines require innovative manufacturing processes and technologies. Many high-tech companies like Apple, Samsung, Google, and Huawei rely on advanced manufacturing technologies to manifest their innovative engineering design concepts into tangible products.
The Rαβγ categorisation framework for dexterous robotic manufacturing processes
Published in International Journal of Production Research, 2022
Some limitations of the Rαβγ were identified. The framework does not address safety issues. This is an important consideration in robotic manufacturing processes, especially when humans are involved. Safety aspects may be included in one of the existing tiers, e.g. the Task tier or considered as an additional tier (δ), however, this issue is left for further research. An additional limitation is the absence of soft aspects such as social or behavioural aspects. The importance of such aspects, e.g. workers’ development and training, has been identified as important for advanced manufacturing adoption (Marcon et al. 2021) and was mentioned by some experts. Investigating such aspects is left for future research. The framework addressed dexterous robotic processes and was not tuned to characterising fully manual processes. Categorising manual production processes requires substantial modifications and should be considered in the future.

Different advanced manufacturing systems and modes have been proposed to generate a faster market response, higher product quality, lower resource costs, better manufacturing services, cleaner production processes, more flexible manufacturing flows and higher knowledge integration. Representative research topics include flexible manufacturing (Buzacott and Yao 1986), cellular manufacturing (Singh 1993), computer-integrated manufacturing (Singh 1995), virtual manufacturing (Shukla, Vazquez, and Chen 1996), agile manufacturing (Gunasekaran 1998), holonic manufacturing (Van Brussel et al. 1998), networked manufacturing (Montreuil, Frayret, and D’Amours 2000), manufacturing grids (Fan et al. 2004), and crowdsourcing (Brabham 2008). These product manufacturing modes and systems have become the cornerstone of the modern manufacturing and industry. However, these product manufacturing modes have not been more widely applied. Product manufacturing has faced significant challenges in adapting to the trends of globalisation, informatization, socialisation, and service. Thus, constructing intelligent product manufacturing modes to address this new environment has become a hot research topic in the manufacturing industry.
Simultaneous part input sequencing and robot scheduling for mass customisation
Published in International Journal of Production Research, 2022
Advanced manufacturing technology and automated equipment are used in modern manufacturing environments. Some factors that affect system performance are machine breakdowns, rush orders, and high-tech devices such as RFID. Our proposed approach can reduce the effect of such factors because the part input sequencing and robot scheduling decisions are made continuously in real time and simultaneously, resulting in better performance.
