TL;DR: In this article, a non-consumable, interchangeable friction stir probe body is used to engage a workpiece material to perform a friction stir process by rotating about an axis thereof and directing a weld material toward a distal end of the probe body along the flow path.
Abstract: A friction stir processing tool and method for manufacturing the same are provided. The tool includes a non-consumable, interchangeable friction stir probe body. The tool includes a material flow path defined by an outer surface of a probe body, which has a non-linear, continuous, monotonically-decreasing axial profile. The probe body is adapted to engage a workpiece material to perform a friction stir process by rotating about an axis thereof thereby directing a weld material toward a distal end of the probe body along the flow path. The flow path varies in pitch as the lateral cross-sectional dimension of the probe body decreases toward the distal end thereby causing the weld material to maintain a controlled speed as it travels along the flow path. Geometric surface features such as threads, helical grooves, ridges, flutes, and/or flats, integrated with the probe body may define the flow path.

12 May 1992TL;DR: A modular approach is presented for constructing Petri-net models for a class of flexible manufacturing systems (FMSs) composed of a transportation vehicle and several functional groups of entities such as machines and buffers that are adaptable to various task flow requirements.
Abstract: A modular approach is presented for constructing Petri-net models for a class of flexible manufacturing systems (FMSs) composed of a transportation vehicle and several functional groups of entities such as machines and buffers. The resulting model preserves the geometric characteristics of the transportation subsystem as well as the flexibility of alternative routes for material flow in an FMS. By separating the machine-dependent part from the whole system, the final model in a modular structure is adaptable to various task flow requirements. In addition, the methodology can deal conveniently with a reconfiguration of the transportation layout. >
