Asymmetric Two Points Incremental Forming: Improving Surface Quality and Geometric Accuracy by Tool Path Optimization

Asymmetric sheet incremental forming is a relatively recent sheet metal forming process
introduced to reduce the costs of sheet metal forming when lowvolume batches, customized
parts or prototypes have to be manufactured. In recent years, this forming process saw a
very fast development, thanks to the researches conducted by many international research
centres considering different process configurations and part geometries. The present work
deals with the optimization of the tool path in two point sheet incremental forming with
full die, in a particular asymmetric sheet incremental forming configuration. The aim of the
study is the experimental evaluation and optimization of the tool path, in order to reproduce
an automotive component with the best dimensional accuracy, the best surface quality and
the lowest sheet thinning.
