AbstractA novel tribologic system was developed in which
volatile lubricants (carbon dioxide---CO2 or nitrogen---N2) were
used as a substitute for mineral oil-based lubricants in deep
drawing processes. This process allows an intermediate medium to
be introduced into the tool contact surfaces under high pressure
by flow-optimized, laser-drilled microholes. This eliminates the
need for subsequent cost-intensive cleaning processes as
volatile lubricants evaporate while expanding to ambient
pressure without leaving any residue. This article gives an
overview of the current findings to enable and characterize the
novel tribologic system. The areas of microhole laser drilling
by ultrashort pulsed laser radiation, characterization of the
novel tribologic system and realization of the system using a
prototype tool will be described.
