“…This justifies the relevance of force signal for monitoring the FSW process. Earlier, the cloud-based monitoring systems have been utilized for induction motor, electro-discharge machining, and power plant machinery reporting benefits of less infrastructure requirement and flexibility [14][15][16]. However, there is scanty literature on the usage of the cloud for monitoring and control of such discrete manufacturing processes, with few conceptual articles mentioning the possible architectures.…”

This paper demonstrates a real-time process monitoring and control framework for the implementation of Industry 4.0 in manufacturing. For a case study, friction stir welding (FSW) has been selected owing to its extensive usage of welding in various manufacturing sectors. Force data has been collected online during the welding and sent to a cloud server enabling telewelding. It is processed through several signal processing and machine learning (ML) techniques for assessment of the weld quality. A control system thereafter controls the weld quality for avoiding the occurrence of weld-defect in realtime. Two ML models have been built, one for assessment of the weld quality, and the other for forecasting the controlled parameters for avoiding defect occurrence. For manufacturing sectors involved in mass production, this technique will be useful to keep a track of the process in real-time and avoid rejection of material in case of occurrence of an anomaly in the process. It is always beneficial for the manufacturing industry to track the quality of a product in real-time, and control the rejection rate, both of which have been successfully shown in this paper.

“…[1] They have applications in integrated circuit packages, fuel injection nozzles, spinneret holes, biomedical filters, film cooling holes of turbine blades among many others [2]. Of late, the research activities in this field are focused on improving the competency of EDM by online monitoring [3] and modifications in tool geometry [4]. Carbide helical end mills have been used performing EDM or Ni alloy as the tool geometry provides better gap conditions and debris removal [5] which in turn leads to better hole quality in terms of surface finish, improved form and reduced taper angle.…”

In the work, the design and development of a novel Wire-EDM setup with double-wire guide discs is presented. It facilitates sparks to be generated between the workpiece and wire at two locations separated by the helical pitch distance. This sparking causes two helical grooves to be generated simultaneously on the surface of the workpiece when it is given suitable rotational speed and table feed. In this work, machining is carried out on rods of 1.5 mm diameter. Helical groves with helix angles ranging from 35 to 500 were generated and characterized. This method of machining the double helical grooves with a single pass reduces the machining time and eliminates the complexities involved in machining one groove at a time. It was observed that the proposed method is suitable for machining double helical grooves with helix angles in the range of 40 - 50°. The parts produced by the mentioned method can be used as EDM tools for generation of high aspect ratio holes in turbine blades and injection nozzles.
