Abstract
Titanium sheet-metal is extensively used for aerospace and biomedical applications. The
diversified customer's demands have created a recent trend towards the small batch
production. In this context incremental forming has attained great attention. Therefore,
experimental machines are designed and manufactured to simulate the harsh forming
conditions. In the fretting machine the combination of a normal force and small vibrations
may constitute a wear phenomenon known as fretting wear. The friction and wear
properties of the tool, lubrication and work piece materials are tested using the sliding
test machine. The steps to evaluate and develop these machines as research tools are
illustrated and discussed. The fretting- and sliding machines help to investigate suitable
forming tools, forming parameters and lubricant strategies for incremental forming of
titanium. It is concluded that these simulation tools provide more efficient and cost
effective ways to understand the effects of changing the forming conditions.
