“…This is due to the reason that with the hike of current high discharge energy is transferred to the machining area, so that melting and evaporation take place, resulting in the formation of a small crater [15]. Also, deep craters were formed by the successive electrical discharge and vaporized the work specimen [25]. The results of this study agree with [24].…”

This research work explores the connection of machining parameters, i.e. peak current (I p), pulse on-time (T on), pulse off-time (T off), tool material (copper, copper-chromium, graphite) and powder particles (tungsten carbide, cobalt, boron carbide) on surface roughness (SR) for Inconel-800 superalloy in powder mixed electrical discharge machining process (PMEDM). The Box-Behnken design had been applied to design the experiments, and response surface methodology (RSM) was employed to cultivate the empirical models. Forty-six experiments were conducted as per Box-Behnken method of RSM. The results indicated that when current increases from 4 to 12 A, SR increases from 4.23 to 12.57 μm, while with the increase of T off from 30 to 60 µs, SR decreased from 9.23 to 7.10 μm. Results also indicated that copper as a tool electrode and boron carbide as a powder additive has significantly effect on SR. The predicted results based on developed models are found to be in good agreement with the experimental results reasonably well with the coefficient of determination 0.96 for surface roughness. Furthermore, certain machined specimens were analyzed using energy-dispersive x-ray analysis (EDX) and scanning electron microscope (SEM) techniques.

“…The optimal values were obtained from the RSM based on careful planning and execution. Lin [23] evaluated the machining characteristic of micro-EDM using response surface methodology. The central composite design (CCD) is an efficient technique that could be applied to modeling of micro-WEDM in RSM.…”

a b s t r a c tMicro-machining technology is effectively used in modern manufacturing industries. This paper investigates the influence of three different input parameters such as voltage, capacitance and feed rate of micro-wire electrical discharge machining (micro-WEDM) performances of material removal rate (MRR), Kerf width (KW) and surface roughness (SR) using response surface methodology with central composite design (CCD). The experiments are carried out on titanium alloy (Tie6Ale4V). The machining characteristics are significantly influenced by the electrical and non-electrical parameters in micro-WEDM process. Analysis of variance (ANOVA) was performed to find out the significant influence of each factor. The model developed can use a genetic algorithm (GA) to determine the optimal machining conditions using multi-objective optimization technique. The optimal machining performance of material removal rate, Kerf width and surface roughness are 0.01802 mm 3 /min, 101.5 mm and 0.789 mm, respectively, using this optimal machining conditions viz. voltage 100 V, capacitance 10 nF and feed rate 15 mm/s.

Because frozen foods have various quality characteristics, an optimization of a cryogenic freezing process is a complex task. This study proposes a compromise simplex method (CSM) using regression analysis to determine four optimal controllable process parameters corresponding to multiresponses for the level of three product quality characteristics. The results of the experimental process for the modified simplex method and multiple response surface optimization model both outperformed the results of the existing operating conditions, thus verifying that the CSM result in food preservation with the product quality measures close to customer satisfaction. The four recommended optimal conditions were as follows: the freezer set temperature of −100C, exhaust fan speed at 10 Hz, retention time of 12 min and counter-current nitrogen flow. PRACTICAL APPLICATIONSThis study optimized multiple responses for chicken drumsticks in a cryogenic freezing process. This optimization method has potential for practical application. All compromised quality characteristics are of topmost importance to the frozen food industry. This method, with some modifications, can also be used in further studies of related food products.
