processes
areas such as the basic tool body are manufactured conventionally,
while more complex areas with integrated
functions are built up additively [14,15] .
Desiderates for future applications of additive processes
in cutting tool manufacturing lie particularly in the field
of material development. In addition to ceramics, some
metallic materials such as tungsten carbide can already
be processed as additives for limited areas of application,
for example in mold making and for tools used in forming
technology [16,17] . However, the existing additive processes
in the field of solid carbide tools are still proving to be unsuitable,
since cutting edges that are able to withstand the
high mechanical requirements cannot currently be produced
in sufficient quality using additive processes [2,17] .
Conclusion
The term Additive Manufacturing represents different
technologies that build components layer by layer via
digital information using diverse materials such as metals
or plastics. Since AM requires no individual tools or fixtures,
it is particularly suited for rapid prototyping, special
tools and small lot sizes. From an economical and technological
perspective, crucial advantages are an increased
design freedom, including the ability to exploit topology
optimization for lightweight applications. Moreover, AM
has the ability to incorporate added functionality such as
internal cooling channels and provides highly complex geo
metries like hollow structures beyond the limits of conventional
manufacturing. Reducing the lifecycle time between
concept, design and actual manufacture makes the additive
processes economically feasible. To exploit the innovative
potential of AM beyond existing solutions, further
research needs to be undertaken with regard to upstream
and downstream processing steps and the enhancement of
varied application scenarios. From today’s view, AM is an
interesting technology with regard to the tool body – for
application in the field of “cutting edges”, further technological
developments must be realized.
