Analysis of the influence of EDM parameters on surface quality, MRR and EW of WC–Co

Optimization of Surface Roughness in Precision Finish Cut Edm Using Taguchi Approach

“…The largest spread of pulse current indicates its significance in spark process followed by other parameters. [11,12] Hence pulse current and spark discharge area are prime parameters in controlling the surface roughness. In regard of the pulse current, the value of surface roughness increases when this factor is increased as shown in the figure 7.…”

Role of Heat Transfer on Process Characteristics During Electrical Discharge Machining

“…In order to maintain the accuracy of machining, EW compensation has been reported to be an effective technique, where wear was continuously evaluated by sensors and the compensation was made (Bleys et al, 2004). Some researchers have tried to develop mathematical models to optimize the EW and MRR (Puertas et al, 2004;Kunieda et al, 2004). It was reported that MRR can be substantially increased with reduced EW using a multi-electrode discharging system.…”

Microstructure, wear resistance and microhardness of W-particle-strengthened Ti6Al4V composite produced with laser metal deposition

“…However, due to its composition, W cannot be machined effectively by means of traditional procedures. 6 Instead, it can be machined using non-conventional methods such as laser metal deposition (LMD). Laser surface modification is utilised to improve the surface of a workpiece because it increases the life of the workpiece while reducing the manufacturing cost, 7 and it guarantees the surface hardness.…”
