| Abstrakt: |
A method is described for the automatic design of assemblies of modular fixturing elements. Its input is a description of the workpiece geometry, the machining envelope, and the position and types of location, clamping, and support elements. Its output is an automatically generated fixture design. The program incorporates systematic design procedure in conjunction with a large library of rules governing the movement and combination of the modular elements. A key feature of the system is the development of a new spatial representation technique. This technique permits the program to search and identify both objects and object intersections. It is also able to determine the position of objects during the design process. A design example is given to illustrate the method. [ABSTRACT FROM AUTHOR] |
