| Abstract: |
A fixture process and method is provided for developing a complete set of all admissible fixture designs for a workpiece which prevents the workpiece from translating or rotating. The fixture processor generates the set of all admissible designs based on geometric access constraints and expected applied forces on the workpiece. For instance, the fixture processor may generate a set of admissible fixture designs for first, second and third locators placed in an array of holes on a fixture plate and a translating clamp attached to the fixture plate for contacting the workpiece. In another instance, a fixture vice is used in which first, second, third and fourth locators are used and first and second fixture jaws are tightened to secure the workpiece. The fixture process also ranks the set of admissible fixture designs according to a predetermined quality metric so that the optimal fixture design for the desired purpose may be identified from the set of all admissible fixture designs.

What is claimed:
1. A modular fixturing system for fixturing a workpiece, comprising:
- a fixture plate including an array of holes separated by a predetermined spacing for placing first, second and third locators thereon;
- a translating clamp attached to said fixture plate for contacting said workpiece between said first, second and third locators and said translating clamp; and
- a fixture processor for receiving a geometric representation of said workpiece and geometric access constraints of said workpiece, for receiving data on said array of holes of said fixture plate and said first, second, and third locators, and for generating a set of admissible fixture designs which define positions for said translating clamp and said first, second, and third locators and which provide form closure based on said geometric representation of said workpiece, said geometric access constraints of said workpiece, and said data on said array of holes of said fixture plate and said first, second, and third locators.
