This system according to the modular design principle, in to the aggregate machine-tool functional analysis foundation in, the aggregate machine-tool will divide into the different level, each level including a series of modules. The system according to the aggregate machine-tool modulation design characteristic, all establishes the corresponding three-dimensional model template to each level module. The user may defer to own needs to choose the template, the input parameter, the renewal model, carries on from the top design. In the graph storehouse three-dimensional model is controls the model according to the user input parameter the renewal. The model parameter divides into the main parameter and the secondary parameter. In establishment components model time, must carry on the analysis to the components structure, determined can reflect the components important function structure the main parameter, the determination secondary parameter and the main parameter relations. The user from the interactive contact surface input main parameter, the system the main parameter took the inquiry corresponding complete parameter, transmits again gives the model, carries on the model the renewal.For example, regarding the hydraulic pressure sliding table, the main parameter is the sliding table width. After the system accepts the user input the main parameter, inquires the sliding table other parameters in the database to renew the entire model. All levels of module graph storehouse divides into 2 kind of types: Single components and unit. Regarding single components, model including structure size parameter, regarding standard letter and standard part, model intake conditions generally only then or minority several, like side foundation intake conditions namely for side foundation model. Regarding unit, except structure size parameter, but also includes the assembly restraint parameter. In this system parameter graph storehouse design process, the assembly model has used UG the WAVE technology, will assemble the model to form 1 control structure according to the design rule, will define the geometry information and the parameter in among which will need, will cause in the aggregate machine-tool all levels of template assembly model between the sub-module geometry characteristic all will be the whole correlation.
