There has been a growing demand for producing
high quality products at low cost considering
the global environment in the production line.
Process tribology is one of the key technologies
to fulfil this demand. The role of the process
tribology and the standpoint of tribo-simulators
are discussed and evaluated. The object of the
process tribology is not only to improve the forming
limit and the die life but also to save energy.
Damage of metal forming dies is identified and
two counterplans are proposed. One of the counterplans
is the flow chart reaching the goal to improve
the die life and the other is the necessity to
structure the system and to foster specialists
dealing with process tribology. Points of the
method of using die materials and surface coatings
are shown for correct application, and new trends
of lubrication technology are summarized. The
present state of the technologies for measuring
mechanical and thermal loads is also summarized,
and the studies on predicting the die life are
presented.
