1. A system that uses a virtual reality environment to create a design model and generate numerically controlled (NC) machining trajectories for use in fabrication of the model, said system comprising:

  • display means for displaying in real time the three-dimensional images of a virtual environment with virtual machines, tools, workpieces and objects;

    manipulation means for navigating through the virtual environment, sizing the virtual objects, and changing the positions and orientations of the virtual objects;

    tracking means for measuring the position and orientation of a user'"'"'s hand;

    sensing means for detecting touch or measuring force;

    application means for applying a sense of touch or feedback force to the user;

    communication means for allowing remote natural communication between multi-users participating in the design creation process; and

    computation means for creating said design models and generating said NC machining trajectories by obtaining inputs from said tracking means and said sensing means and generating outputs to said display means, said manipulation means, and said application means;

    wherein said system operates in its entirety in real time, and design parameters and machining parameters defined by the operation of said system are output for at least one of direct application to a manufacturing protocol and review by a designer.
