PURPOSE Commercially pure titanium (CP Ti) has been recognized in dentistry for its biocompatibility, good mechanical properties and corrosion resistance. Conventional manufacturing processes can affect surface quality and result in poor bonding of dental ceramics to CP Ti. This is why powder metallurgy (P/M) and wire electro-discharge machining (WEDM) are being introduced in the manufacturing ...

Fatigue performance is a major consideration for critical aerospace components. The influence of surface grinding and rough/finish wire electrical discharge machining (WEDM) on the high cycle fatigue binary Ti 50.8 -Ni 49.2 shape memory alloy was assessed. effect machined workpiece integrity in terms roughness subsurface microhardness results also evaluated, addition to fractography analysis. T...

Wire-EDM is a highly complex machining process, which is characterized by non-linear behavior. Owing to unique capabilities of machining complex shapes and hard materials with high accuracy and fine surface finish, WEDM is used in various manufacturing industries. There has been on-going research to develop automated capabilities for WEDM by understanding the interaction mechanism of various in...

surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. a good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. on the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and incr...

Electrical discharge machining (EDM) can use soft tool electrodes to process hard workpieces achieve “soft against hard”, because it directly uses electrical energy and thermal remove metal materials. Then, generate complex features on harder materials meet the requirements of excellent surface quality. Since EDM involves many parameters, including non-electrical properties, is essential optimi...

In Wire Electrical Discharge Machining (WEDM) the breakage of the cutting tool (the wire) reduces the process performance and the required accuracy. Previous works of authors showed that the behavior of the basic signals of the process (current and voltage) can be employed to detect degraded situations that can lead to wire breakage. In particular, different types of degraded behaviors in two c...
