“…However, these techniques have their own limitations, in the perspective of deteriorated surface quality (cracks, heat affected zone, recast layer), high cutting forces and alteration of mechanical properties. These defects result into decrease in hardness, wear resistance and corrosion resistance of machined surface and also affect the product quality [22][23][24][25][26][27][28][29][30][31][32].…”

WC-Co composite material is highly demanded in manufacturing industries, because of its unique properties such as excellent hardness with toughness, higher mechanical strength, good dimensional stability etc. This present investigation is aimed at studying the impact of different experimental conditions (by varying cobalt content, thickness of work piece, tool profile, tool material, abrasive grit size and power rating) on responses of interest (material removal rate and tool wear rate) in ultrasonic drilling of WC-Co composite material. The experiments have been planned by using Taguchi's L-36 orthogonal array and grey relation analysis has been applied for optimization of multiple responses. Analysis of variance (ANOVA) is also employed to find the significant factors. Significant effects are observed for process variables such as cobalt content, abrasive grain size and power level. Tools with higher hardness delivered better machining performance.

In this paper, experiments are conducted by machining from different crystallographic orientations of monocrystalline silicon, and the effects of crystallographic orientation on the micro electrical discharge machining (EDM) process are discussed. The results demonstrate that the machining speed and surface roughness are varied when crystallographic orientation changes. The surface roughness is seen to vary by as much as twofold with crystallographic orientation, while the ratio between the maximum and minimum values of material removal rate is 1.76. The unique material removal mechanism of micro EDM enhances the effects of crystal anisotropy on micro electrical discharge machining process.

“…The parameters were optimized in an effort to improve the working performances for the WEDM processes of SKD11 steel [3], EN 353 steel [4] and AISI D3 [5] material. Additionally, investigators solved the trade-off among multi-responses for the WEDM processes of YG15 steel [6], AISI D2material [7] and Inconel alloys [8,9]. Recently, optimal processing conditions for the WEDM processes of composite materials were studied [10][11][12].…”

Improving the technical performance of the wire electro-discharge machining (WEDM) process is an effective solution to decrease manufacturing costs. This paper addresses a multi-response optimization to simultaneously improve the cutting area rate CAR and decrease the kerf width AKW, while the average surface roughness ASR is predefined as a constraint. The processing conditions considered include the pulse-on time T on , the current I, the voltage V and the wire speed S. A WEDM machine was adopted in conjunction with the Box-Behnken matrix to conduct experimental trials for machining of SKD61 steel. Highly nonlinear relationships between machining parameters and technological outputs were developed using the Kriging models. Finally, an archive-based micro-genetic algorithm (AMGA) was used to resolve the trade-off analysis among three responses and determine the optimal values of the processing factors. The results showed that a set of feasible solutions can be determined for the low kerf width as well as the surface roughness and the high cutting area rate. The selection of optimum parameters could help the WEDM operators to save the machining costs and time. The combination of the Kriging model and AMGA could be considered as an intelligent approach for modelling WEDM processes and predicting optimal results.
