Graphics Subsystem of the Vertical Workstation of the Automated Manufacturing Research Facility at the National Bureau of Standards

摘要

Automated Manufacturing Research Facility, metal parts are machined automatically from a feature-based design. A simple two-and-a-half dimensional part may be designed and machined within an hour, allowing half the time for design input. The Graphics Subsystem of the VWS software is used for drawing part designs and workpieces by the VWS Part Design Editor and Data Execution module. Graphics capabilities are also available through a friendly user interface. The Graphics Subsystem is built on the 'SunCore' graphics package which has been interfaced with Franz Lisp. Designs and workpieces are drawn in three 2-dimensional views, as on a standard mechanical drawing. A variety of graphics capabilities and techniques are employed to carry out the functions required, including indexing, masking, picking, locating, scaling, translation, segmentation, restoring saved images, etc.
