Process Planning for a Milling Machine From a Feature-Based Design
Thomas R. Kramer
In the Vertical Workstation (VWS) of the NBS 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. With a design already in hand, the VWS software (which is written in LISP and runs on a Sun computer) will automatically prepare a process plan for a milling machine for making a part of the given design. The heart of the process plan is a list of machining operations to be carried out. The operations are selected by the system from among it repertoire of 21 possible operations. The process plan also includes a header and a list of tool requirements. The process plans produced by the system are later used as input to an automatic NC-coding system which writes code for the milling machine''s controller.
