Abstract
Tolerancing and surface finish data are essential for automatically planning the manufacture, inspection, and robotic assembly of mechanical components. A scheme for representing surface features in a solid modeler based on constructive solid geometry (CSG) and for associating tolerances and other attributes with such features. It shows conclusively that commonly-held beliefs on CSG's inability to deal with surface features and tolerances are unfounded. The scheme has been implemented in the PADL-2 modeling system and is being used to support research on high-level languages for programming numerically controlled (NC) machine tools.Keywords
