After modification, users can control and simulate the machine tool generated on puter monitor. If user does not satisfy with the initial alternatives, user can regenerate them after adding new modules or new module bination rules. The VMSM supports the modification process by providing user interfaces to edit module specifications, contact relations between modules, accessory modules, etc. In Figure 3, various types of machines tools are presented to show the proposed modeling methods. A vertical (left) and a horizontal (right) machine tool are presented in the Figure 3. 4. Virtual Machine Application . Manufacturing Industry Supporting VMT Application Both with “technology push” and “market pull”, users demand lower technology costs, more efficient utilization and manpower performance improvements .To the developers of VMT technology and to those working closely with industrial pioneers to produce real applications, the value of VMT application has been unquestionable. A “classic” industrial study was conducted at Ford39。 2020 2. Modeling of Virtual Machine Tools To systematically generate the structure of machine tools in virtual reality environment in response to different requirements, definitions of ponent modules and the relations between them are structure of machine tools is represented by a connectivity graph. Component modules of machine tool contain the information on size, motion, motion type, etc. and are stored in a module library. Functional and shape characteristics of ponent module are utilized to visualize machine tools on puter and to derive contact and kinematics relations. Contact relations show the linkages between adjacent ponent modules. Various types of feasible machine tools’structure can be derived by applying module bining rules, which regulate the mating feasibility of two ponent modules. Finally, kinematics relations required to show the motions of machine tools can be derived by using functional characteristics of modules and connectivity relations. Figure 2 shows the relationships between the modeling elements of machine tools’ structure [10]. . Geometric Model Based on the virtual machine tool configuration, the shape of the machine tool can be graphically represented. Since the machine tool is a kinematic chain of mechanical ponents, it can be displayed by bining the geomet
