Silk from the Bombyx mori silkworm is a protein-based fiber. Bombyx mori silk fibroin (SF) is one of the most important candidates for biomedical porous material based on its superior machinability, biocompatibility, biodegradation, bioresorbability, and so on. In this paper, we have reviewed the key features of SF. Moreover we have focused on the morphous, technical processing, and biocompatib...

A number of materials have recently been developed specifically for advanced ultrasound applications. These are high-density ceramics, fine grain ceramics, high dielectric constant ceramics, and single crystal piezoelectrics. Improvements in properties resulting from these materials range from greater strength and improved machinability to increased transducer element capacitance and coupling. ...

In the present paper based on feature recognition algorithms and data extraction from IGES files, an integrated process planning system (CAPP) is introduced. The classification of workpiece features and with their aid the workpiece process plan are automatically determined. The developed CAPP system considers the part machinability as well as the existing in a factory facilities, it is independ...

Most of the materials used in the industry of aero-engine components generally consist of titanium alloys. Advanced materials, because of their excellent combination of high specific strength, light weight and general corrosion resistance. In fact, chemical wear resistance of aero-engine alloy provides a serious challenge for cutting tool material during the machining process. The reduction in ...
