Research Of Worm And Worm Gear CAPP System Based On Feature Modelling

The worm drive has large transmission ratio , compact structure, small impact load, transmission placidity, low noise, self-locking and so on, thus widespread application all kinds of machinery. with the market demand unceasing development, it is more and more high to the worm drive request.This article has emphatically conducted following several aspect research base on the analysis and the research existing research results foundation,.1. The multianalysis worm gear three-dimensional parametrization modelling and CAPP specification, proposed how to increase the function of CAD/CAPP system by inventing the models on the existing CAD system,improving the ability of intelligent design on some occasion, and analyzed discusses has realized this function key technologies.2. It adopts the helical scan to eliminate the material function and the change reference plane law has realized the precision high three dimensional modelling using API provided by SolidWorks and VB. Realizes the worm and worm gear three-dimensional feature modelling design under the SolidWorks environment, calculates mathematical model which the feature modelling needs, then obtains its mathematics analysis formula, has completed the numerical modelling. designed user interface and input primary data, the computer completes the components automatically the three-dimensional characteristic modelling, simultaneously produces the engineering plat, prepares for the following technological design.3. In analyzes the CAPP function and the realization crucial technology foundation, unifies the mature design data and the manufacture craft, makes equipment parameters and so on, establishes the related information database, realizes basic parameter and the craft parameter management, can complete the functions of search, edition, increase, deletion and so on, each function realization has provided the backstage support for the system, thus realization worm gear CAPP.Take the above research as foundation, applies the VB development application procedure, applies the Access software establishment database, carries on the visit through the ADO data accessing technology to it, has developed based on the feature worm and worm gear adjuster feature modelling CAPP system.
