               characterized by its wider tooling flexibility, which can be realized by
               exchanging the cutting edge module in accordance with the machining
               requirements. Actually, a tooling system consists of the shank (fixing),
               adapter (extension), and cutting edge modules, and the adapter module
               may assist to reinforce the further flexibility [1]. This tooling system was
               employed on a CNC (computerized numerical control) lathe of the George
               Fischer make (type NDM-16), in which the cutting edge modular was
               stored in the tool magazine of drum type and transferred to the machin-
               ing space by the overhead traveling robot. Figure 1-2 displays another
               modular tooling system produced by Nikken Co., showing the effec-
               tiveness of the modular concept even in the year 2000. The modular prin-
               ciple was furthermore applied to the tool layout on the turret, e.g., base
               and tool holding blocks, as shown in Fig. 1-3 [2].
