    • A CAD model of a component is designed by means of a CAD system that modifies the shape of the design of the component represented by the CAD model by means of templates held in a database of templates. The templates include machining data concerning the machining actions necessary to effect the alteration, represented by the template, of the shape of a work-piece. The CAD system outputs a computer model of the component comprising not only part geometry data concerning the shape of the component but also machining geometry data concerning the machining actions necessary for manufacturing from a work-piece a component having a shape in accordance with the outputted model of the component. This outputted computer model is then converted into an NC (numeric control) program by means of an NC program conversion module, by extracting NC code sequences from a database, the NC code sequences extracted corresponding to the templates of the UDF library used to design the shape of the CAD model.
    • 通过CAD模块设计组件的CAD模型,该CAD系统通过模板数据库中保存的模板修改由CAD模型表示的组件的设计形状。 模板包括关于用于实现由模板表示的改变所需的加工动作的加工数据的工件的形状。 CAD系统输出组件的计算机模型,不仅包括关于部件形状的部件几何数据,而且还包括关于根据输出模型的具有形状的部件从工件制造所需的加工动作的几何数据加工 的组件。 然后,通过NC程序转换模块将该输出的计算机模型转换为NC(数字控制)程序,通过从数据库提取NC代码序列,提取相应于用于设计数据的UDF库的模板的NC代码序列 CAD模型的形状。

    • A system and method for fabricating a thermoplastic prosthetic limb socket from a thermoplastic preform cone involves the steps of: obtaining a digital or physical positive representation of a patient's residual limb; determining a desired thickness for the thermoplastic socket; selecting a thermoplastic preform cone; calculating the dimensions of a proximate extension to be added to the proximate end of the digital or physical representation of the patient's residual limb based upon the dimensions of the patient's residual limb, the dimensions of the preform cone, and the desired thickness of the thermoplastic socket; forming a positive socket mold based upon the combined dimensions of the patient's residual limb and the extension; heating the preform cone; and stretching the preform cone over the positive cast. Preferably the method is performed on a CAD tool. The processing unit in the CAD tool has access to the dimensions of the residual limb, the desired thickness of the socket and the dimensions of the preform cone; and is thus able to compute the dimensions of the proximate extension based upon a set of algorithms stored in the form of a software package (or program) accessible and executable by the CAD's processing unit.
