20   Modular Design Guide and Machine Tools Description

               1.3    A Firsthand View of Developing History
               and Representative Applications
               The first meaningful trial of the modular design is credited to the late
               Prof. Königsberger in the beginning of the 1930s on the basis of his first
               application of the unit construction to the milling machine of Wanderer
               brand [6].
                 Figure 1-11 is a firsthand view of the chronological history of the mod-
               ular design, showing in part the change in terminology. As can be seen,
               the modular design has been developed continuously in responding to
               the changing requirements of the machine tool, and it was also deployed
               to various extents, encompassing the production system and machine
               tool accessories. As quickly described earlier and will be detailed later,
               the production system has often been converted to a compact machine,
               for instance, those from FMCs to system machines. In this context, the
               modular design has functioned very well to form the suitable structural
               configuration. In the following, the quick notes on the history of modu-
               lar design will be stated using, if necessary, the historical nomenclature
               while emphasizing the epoch-making events and showing the repre-
               sentative applications of world class. Actually, the three milestones can
               be observed as follows, when we scrutinize the developing history up to
               now.
