relation to the integration and disintegration of required machining
processes for the objective works. In addition, the conventional FTL
consisting of the MC of line type must have the following features.

1. Structural configuration of column traveling type with modular
design, as shown in Fig. 1-23
2. Higher efficiency and reliability
3. Functionality for ease of maintenance and repair
4. Functionality for ease of swarf removal
5. Reduction of floor space in terms of machine width

In consideration of the characteristic features, furthermore, the units
have been standardized across the whole nation and, in the preferable
case, across the whole world to increase the obtainable benefit. In fact,
the United States and Germany had enacted the national standard in
the 1960s and on the extension of these national standards, the ISO
(International Standards Organization) has legalized the due standards
in the 1970s [19]. In short, the ISO enacted some international standards
for both the TL and rotary indexing machine in the beginning of the
1970s. Figure 1-25 shows a firsthand view of these standards, and as can
be seen, the designer must refer to a handful of standards. In addition,
