“…Pawelski [20] summarised the advantages and drawbacks of similarity theory for metal-forming applications and indicated that it is a useful way to assist the scaling of some simple metal-forming processes in which key process variables can be determined. But limitations of similarity theory exist once metalforming processes become complicated, especially when highly non-linear boundary, lubrication and thermal conditions need to be considered [21,22]. Recently, Davey et al [23] introduced a transport equation approach to provide guidance for designing a scaled thermo-mechanical metal-forming experiment.…”

A scaling method is developed for the creep age forming (CAF) process to downscale manufacturing of large/extra-large panels to lab-scale experimental trials for industrial application. Similarity theory is applied to identify both the geometrical and physical (non-geometrical) similarities between large-size prototypes and scaled-down models in all process stages of CAF, including loading, stress-relaxation and unloading (springback). A constitutive model is incorporated into the theory in order to identify the similarity in the highly non-linear stress-relaxation behaviour for aluminium alloy plates during CAF, and to obtain the effective scaling criteria for the CAFed plates after springback. The method was demonstrated by scaling down CAF manufacturing of both singly curved and doubly curved large plates under both proportional and non-proportional geometrical scaling conditions. The analytical results of the scaling method and numerical results obtained by CAF FE modelling were found to be in good agreement. Scaling diagrams linking the key deformation (springback) and structural (flexural rigidity) variables to scaling ratios under both proportional and non-proportional conditions were generated, and the developed scaling diagrams have been validated by corresponding CAF experiments. The scaling method developed in this study provides guidance on the design of scaled-down CAF experimental trials and will be used in the practical CAF process of large/extra-large panels.

There has been an increasing interest in the penetration of magnetic field-assisted machining processes in the industries. Due to the ease of contactless forces, magnetic fields have proved extremely versatile and relatively low cost when considering the potential increase in productivity of existing machining processes that it can provide. In this overview, we review the recent achievements and developments in magnetic field-assisted machining processes and their applications. A wide variety of machining domains are examined including electro-discharge machining (EDM), micro-EDM, electrochemical machining, magnetic-assisted machining and many more. The advantages and limitations of each implementation and potential future research pathways are also discussed.
