A physical design grammar: A production system for layered manufacturing machines

نویسنده

چکیده

This paper addresses the need to generate functionally large geometries/objects for layered manufacturing machines. Novelty is found in the translation from an initial shape in CAD to subdivision as interlocking objects that are further subdivided into slicing layers using traditional layered manufacturing software. Translation from an initial shape to individual component geometry is guided by shape rules as a set grammar that generate a 2D drawing of interlocking shapes. Mechanical rules further shape the 3D geometry of each object, resulting in a virtual model that complies with measures of structural stability, assembly, and machine manufacturing. Three models are constructed to illustrate the translation process from the virtual shape to a manufactured artifact. © 2007 Elsevier B.V. All rights reserved.

Mathematical Modeling for a Flexible Manufacturing Scheduling Problem in an Intelligent Transportation System

This paper presents a new mathematical model for a production system through a scheduling problem considering a material handling system as an intelligent transportation system by automated guided vehicles (AGVs). The traditional systems cannot respond to the changes and customer’s demands and for this reason, a flexible production system is used. Therefore, for this purpose, automated transpor...
