108 Modular Design Guide and Machine Tools Description

together with heavy cutting by preferably leveraging the related dimen-
sional and performance specifications. Obviously, these specifications
cannot be fulfilled simultaneously at present in the design of the
machine tool, which is one of the leading causes for the ill-defined prob-
lem in the machine tool design.
To this end, it is again envisaged that the complexity in the applied
loads due to multifarious machining methods is one of the leading struc-
tural design factors in the machining complex; however, the utmost
serious problem is how to equalize the temperature distribution and
minimize the thermal deformation. Another difficulty lies in the prepa-
ration of the NC software, because of the complexity of the part shape
and one-chucking machining including a hands-off procedure. In other
words, at issue is the leverage between the production volume and the
production cost of the NC software.
