Optimization of operating parameters is an important step in machining, particularly for operating unconventional machining procedure like Wirecut Electro Discharge Machining. Since wire-cut EDM has experienced explosive growth in application users demand and need maximum productivity and through-put, increased accuracy, and predictable performance. Also machines and job requirements vary great...

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. This work...

Multi-objective optimization Genetic Algorithms Robust Design The following paper describes the main objective to follow the methodology used and proposed to obtain the optimal values of WEDM process operation on the machine Robofil 310 by robust parameter design (RPD) of Dr. G. Taguichi [TAGUCHI, G. 1993], through controllable factors which result in more inferences regarding the problem to no...

Technological advancement, on the one hand, makes Electrical Discharge Machining (EDM) much faster. One example of that is the presence of Wire Electrical Discharge Machining – High Speed (WEDM-HS) machine, which makes the material removal rate as high as 80 mm/min. On the other hand, it also make Abrasive Waterjet (AWJ) achieve much better quality surface and tighter tolerance. As a result, th...

In conventional wire electrical discharge machining (WEDM), WC-Co machined pieces can stay for hours in the worktank. pH range of dielectric Co actively dissolves and thus corrosion occur affecting mechanical properties lifetime those pieces. This study demonstrates how applying cathodic polarization through implementation auxiliary electrodes work zone helps reducing in-depth propagation attac...
