to an implantable hip prosthesis, the other detailing a gear pump for handling sev-
eral fl uids. Both examples have provided manufacturing simulations and also sub-
sequent details on fi nal automated manufacture, in the case study linked to CNC
machining of the hip prosthesis.
The simulation of other more novel manufacturing processes is also discussed,
together with an analysis of present challenges and future directions, many of them
connected with the additive manufacturing technologies and approaches explained
in forthcoming chapters.
Computer-aided manufacturing resources are also linked to improving overall
security in plants and industrial installations, as the whole manufacturing process,
including stock management, machine and robotic movements, transportation, and
all necessary operations can be integrally simulated, so as to verify secure zones for
operary movements.
Additional incorporation of interesting features for analyzing the infl uence of the
manufacturing process and its conditions, not only on fi nal part geometry and qual-
ity, but also on expectable mechanical properties, for subsequent linkage to
computer-aided engineering resources for FEM-based calculations on fi nal perfor-
mance, would be desirable.
Finally, it is important to note that computer-aided manufacturing is also linked
to several automated additive manufacturing technologies, covered in Chap.

which, instead of working on a subtractive approach, allow for solid freeform fabri-
cation of complex geometries in several materials.
Several of the technologies also described in Chaps.

, when focusing on
micro- and nano-manufacturing technologies and on recent advances linked to bio-
fabrication, are also connected to computer-aided manufacturing, as they work in an
autonomous way based on computer-aided designs, after adequate manufacture
preparation with help of more specifi c CAM software.
Progressive format universalization, for easier information exchange between
CAD resources and aiming at a more direct and automated control of the machines
carrying out manufacturing, with less intermediate conversions and preparation
steps, will surely be linked to the progressive expansion of “factory at home”
approaches and to research topics aimed at deciding the most adequate processes
for the “factories of the future.”
