This paper presents the design and development of a real-time monitoring and diagnosis system for diagnosing degraded cutting regimes in Wire Electrical Discharge Machining (WEDM). The detection in advance of the degradation of the cutting process is crucial since this can lead to the breakage of the cutting tool (the wire), reducing the process productivity and the required accuracy.

Design, fabrication and tests of a monolithic compliant-flexure-based microgripper were performed. The geometry design and the material tresses were considered through the finite element analysis. The simulation model was used to study in detail profiles of von Mises stresses nd deformation. The maximum stress in the microgripper is much smaller than the critical stress values for fatigue. The ...

The application of an electrically conductive diamond material to a new type of grinding wheel whose cutting edges possess electrical conductivity has been tried in this research work. Firstly, electrical discharge machining is applied on a solid surface of an electrically conductive CVD diamond film to create protrusions like cutting edges. Secondly, it is confirmed that the EDMed surface of t...

An analysis of electrical-discharge machined AISI D2 tool steel for high-cycle fatigue is conducted. The damage model was developed to reveal the in£uence of different electrical-discharge machining conditions on the fatigue life. The processed surface layer and the cross-section were examined by scanning electron microscopy (SEM).The experimental results show that the fatigue life of the EDMed...
