Constraints on assembly plans vary depending on product, assembly facility, assembly volume, and many other factors. This paper describes the principles and implementation of a framework that supports a wide variety o f user-speciied constraints for interactive a s-sembly planning. Constraints from many sources can be expressed on a sequencing level,(More)
We brieey describe A rchimed e s 2 , a s e cond generation assembly planning system that both provides a general high-level assembly sequencing capability and, for a smaller class of products, facilitates automatic programming of a robotic workcell to assemble them. Because Archimedes can input CAD data in several standard formats, we have been able to test(More)
A package of five programs centering around the highly flexible, powerful, two-dimensional mesh generation program, QMESH, is presented. Together, the five programs provide a tool for generation, bandwidth minimization and display of meshes with Q4 or Q8 elements. The package's primary purpose is generation of input for finite element analysis programs.

Usage of mathematical library (MATHLIB) routines on the Control Data 6600 system at Sandia Laboratories, Albuquerque, New Mexico, has been momtored for over three years. The value of one input argument during the first execution of each library routine in each job along with the identification number of the user has been monitored for about two years. The(More)
