  Currently, the rapidly developing powerful spinning processes of metals are
widely used in many industrial sectors including those requiring high precision
processing of metal materials, and the types and production of spun part are
increasing. Evaluating the spinnability (flow formability) of material is very
important for expanding the application of flow-forming process for producing a
lot of products. The spinnability of metal is an important basic data that
predicts defects that may appear in the processing of products in advance,
makes it possible to create rational processes, and guarantees product quality.
In this paper, we comprehensively analyze the data studied so far on the
spinnability evaluation during powerful spinning conducted at room temperature,
it was described with respect to the test methods and the theoretical methods
for evaluating spinnability of metallic materials, and the effect of various
factors on the spinnability.
