Parts produced by additive manufacturing (AM) often require post processing to improve surface finish and mechanical properties. However, little attention has been given to including deformation in the post processing. Deformation post-processing can address some part size, manufacturing cost, and geometry limitations of 3D printing. Additionally, it could be used to create 3D surfaces using pl...

In this paper, we present a simulated annealing (SA) and a genetic algorithm (GA) based on heuristics for scheduling problem of jobs in virtual cellular manufacturing systems. A virtual manufacturing cell (VMC) is a group of resources that is dedicated to the manufacturing of a part family. Although this grouping is not reflected in the physical structure of the manufacturing system, but machin...

The large number of requirements and opportunities for automatic identification in manufacturing domains such as automotive and electronics has accelerated the demand for item-level tracking using radio-frequency identification technology. End-users are interested in implementing automatic identification systems, which are capable of ensuring full component process history, traceability and tra...

Rapid manufacturing is emerging as a technology that enables the fabrication of three-dimensional heterogeneous objects. Compared to homogeneous objects, the fabrication of heterogeneous objects is very complicated for the processing of material information especially Functionally Graded Materials (FGMs). To take full advantage of rapid manufacturing, some methods to design and fabricate hetero...

A feature is a local shape of a product directly related to the manufacturing process. In the computer aided process planning, information on manufacturing is essential. To get the manufacturing related information from CAD data, features should be recognized. In this paper, we thoroughly investigate the composite features, which consist of interacting simple features. The simple features in th...

This article introduces a power-efficient, miniature electronic nose (e-nose) system. The e-nose system primarily comprises two self-developed chips, a multiple-walled carbon nanotube (MWNT)-polymer based microsensor array, and a low-power signal-processing chip. The microsensor array was fabricated on a silicon wafer by using standard photolithography technology. The microsensor array comprise...

The RFID technology opens new opportunities to monitor and control manufacturing processes. Therefore more and more manufacturers consider the introduction of RFID in their production lines. However, RFID projects face various challenges when designing the software infrastructure. In this paper we present design principles which guide application designers in developing and adapting RFID soluti...
