摘要: Abstract A novel test method for the characterisation of flexible forming processes is proposed and applied to four processes: Incremental Sheet Forming (ISF), conventional spinning, English wheel power hammer. The developed in analogy with time-domain control engineering, where a system characterised by its impulse response. spatial response used characterise change workpiece deformation created process, but has also been strain spectrogram, as way process physical effect it on workpiece. Physical numerical trials study effects material parameters lead three main conclusions. sheet particularly sensitive parameters. hammer are strongly similar largely insensitive both Spinning develops two stages most parameters, prior deformation. Finally, could be modelling, classification existing processes, product-process matching closed-loop processes.
