“…Yoshida et al proposed a data fusion analysis method consisting of field-oriented interviews, human motion capture and videos from both expert technicians and novices, and the operational differences between those were analysed. Kikuchi et al 38 presented a motion analysis method to extract tacit knowledge, such as expert hand gestures and eye movements, during a composite layup task and their relationship with mechanical properties and dimensional stability of the resulting product. Gu et al 39 developed a Portable Assembly Demonstration (PAD) system using an RGB-D camera, this system could recognize the tool/part used, the action applied and the assembly state characterizing the spatial relationship between the parts.…”

Manual operations feature prominently in the manufacture of many electrical machines. Even though high-volume electrical machine manufacture is dominated by automation, several manufacturing operations continue to involve manual intervention because of the complexity of such operations makes them heavily reliant on high dexterity manual skills and experience. However, quality can be variable due to human involvement. Currently, in order to maintain a high precision of control and required tolerances of the final machine, inspection is performed at various steps during manufacturing and assembly. Detecting a defect at these end-of-line tests can result in significant wasted time and costs due to rework or scrappage. The solution to this problem lies in in-process monitoring particularly for error prone manual operations. This paper presents a literature review of the state-of-the-art available techniques and limitations in process monitoring within the context of electrical machine manufacturing. To quantify the degree of manual activities in process monitoring within electrical machine manufacture, a structured survey of UK based companies was conducted, identifying specific error prone manual processes to target, and gaps in inspection. The survey identified that a significant proportion of activities in electrical machine manufacture are manual, or semi-automated with manual interventions. However, literature review revealed only a limited research in in-process monitoring of manual operations in this area. Finally, two case studies are presented where case study 1 presents a framework for digitisation of a variety of manual manufacturing tasks, and case study 2 demonstrates real-time capture, modelling and analysis of deformable linear objects in electrical machine manufacturing.
