Appropriate description and implementation of internal part traceability in manufacturing is a complex task. Accurate and real-time traceability from a part to a manufacture, storage, or transport issue is essential to efficient and high-quality operations. With the increasing amount of machine status and product quality information coming from the manufacturing lines, a question arises. When t...

Sediment management is guided by both technology and local so-cioeconomic conditions.llpstreaa management in China emphasizesgully control. Warping of land is practiced wherever conditionspermit. Both make use of sediment as an asset. Sediment is alsoused to enlarge Yellov River levees to 50 to 70 m wide.Useful storage capacity of a large reservoir may be preservedpe...

Empowering autonomic control in the enterprise environment highly contributes in the quest for a higher level of flexibility. Multi-Agent Systems (MAS) may be utilized to this end along with the enterprise environment model leading to a decentralization of the manufacturing production processes. The current work proposes a framework along with the necessary software tools for the modeling of MA...

Abstract Additive manufacturing (AM) is well known for supporting the of composites through 3D printing lay‐up tools, sacrificial mandrels, trim molds, etc. The fused deposition modeling (FDM) a pioneer in composite tooling. This technique advantageous many scenarios which it convenient to obtain hollow parts by dissolving removing use expensive and heavy metal molds. However, effects that remo...

superplastic forming (spf) is a manufacturing process utilized in the automotive industry to produce complex geometry aluminum or magnesium alloy components which cannot be fabricated at room temperature. this paper investigates the effects of the die entry radius and the interfacial friction coefficient on the required forming time and thickness distribution of a superplastic formed part. a co...
