“…The author have presented an evolution of the ECDM process in last two decades and suggested future opportunities like vibration-assisted ECDM and magnetic-assisted ECDM. Singh and Singh 16 reviewed the capability of ECDM process; for machining conductive materials like steel, super-alloys as well as nonconductive materials like glass, ceramics, and composites. This is in contrast with EDM and ECM which can be used for only conductive materials.…”

Fiber reinforced composites, also referred as fiber reinforced plastics (FRPs) have gained considerable importance in engineering applications due to their unique qualities like high strength and stiffness at lesser weight, chemical inertness, thermal resistance, corrosion resistance, and electrical resistance. Though the machining of FRPs is not recommended, many times it is inevitable and the primary machining process like drilling is essential. This can cause delamination of the fibers thereby adversely affecting the mechanical properties of the composite and requires additional secondary finishing operation. The present investigation explores electrochemical discharge machining (ECDM) as a one of the novel technique to remove the delaminated fibers from such composites. Using ECDM the protruded delaminated fibers from a drilled hole in FRP have been precisely eliminated. Two different approaches viz. top machining and inside machining were followed for this purpose. Process evaluation was done in terms of its ability to remove the delaminated fibers and the extent of thermal damage (heat affected zone and hole overcut) to the workpiece. Both approaches have shown considerable potential of removal of delaminated fibers precisely.

“…Initially, the ECDM process was successfully used for machining of glass [4]. Later on, its applications were extended to machining of composites [5], ceramics [6], steel [7] and super-alloys [8]. The machining behaviour in ECDM process is significantly affected by electrolytes, tool electrode and other process parameters.…”

“…The machining behaviour in ECDM process is significantly affected by electrolytes, tool electrode and other process parameters. In the detailed literature of ECDM process, various researchers have reported their work in various domains including tool electrode materials, electrolytes, hybridization, machining quality and tool electrode geometries [6,[9][10][11]. In the electrolyte domain of ECDM, the machining of glass has been attempted using alkaline (NaOH), neutral (NaCl) and acidic (H 2 SO 4 ) electrolytes [12].…”

Electrochemical discharge machining (ECDM) is a hybrid process comprising of features of both electrochemical machining and electrical discharge machining. The combined features enable ECDM process to expand its applications to conductive and non-conductive materials. In recent years, several attempts have been made to utilize ECDM process for micro-machining of glass, composites, ceramics, steel, super-alloys, etc. The machining behaviour of ECDM process is significantly affected by several process parameters including electrolytic properties, tool electrode, etc. The present research article focuses on environmental aspects of different electrolytes used in ECDM by analysis of fume mass concentration and characterization of fume particles generated during machining. The average size, morphologies and chemical composition of fume particles were studied by field emission scanning electron microscopy and energy-dispersive spectroscopy, respectively. The fume mass concentration increased from 30.35 to 220.76 mg/m 3 , 15.10 to 98.34 mg/m 3 and 40.56 to 290.0 mg/m 3 with increases in electrolyte concentrations from 20 to 50% of NaOH, NaCl and HCl, respectively. The average size of fume particles generated in ECDM process was less than 100 nm. Additionally, the Fourier transform infrared spectroscopy of breathing air revealed the presence of amines, CH 4 , NO 2 , SO 2 , CO 2 , thio compound disulphides and halogenated hydrocarbons in the breathing zone of operator.

Polymer-based fibrous composites are gaining popularity in marine and sports industries because of their prominent features like easy to process, better strength to weight ratio, durability and cost-effectiveness. Still, erosive behavior of composites under cyclic abrasive impact is a significant concern for the research fraternity. In this paper, the S type woven glass fibers reinforced polymer matrix composites (PMC s ) are used to analyze the bonding behavior of reinforcement and matrix against the natural abrasive slurry. The response surface methodology is adopted to analyze the effect of various erosion parameters on the erosion resistance. The slurry pressure, impingement angle and nozzle diameter, were used as erosion parameters whereas erosion loss, i.e., weight loss during an erosion phenomenon was considered as a response parameter. The artificial neural network model was used to validate the attained outcomes for an optimum solution. The comparative analysis of response surface methodology (RSM) and artificial neural network (ANN) models shows good agreement with the erosion behavior of glass fiber reinforced polymer matrix composites. outer structure faces surface erosion because of the existence of highly abrasive particles in the air [8,9]. The erosion of fibrous composites depends upon various process parameters such as impacting particles, angle of impingement, velocity, etc. Tewari et al. [10] reported that erosion of fibrous composites is significantly influenced by fiber orientation because unidirectional fiber orientation exhibits semi ductile erosion behavior. Pool et al. [11] reported that polymer composite shows brittle erosion behavior whereas permanent aramid fiber epoxy shows quasi ductile behavior. The increase in weight fraction of glass fiber as reinforcement can convert ductile erosion behavior into brittle behavior [12]. The effect of particle size during erosion is also analyzed and reported that erosion rate of the composite surface is directly proportional to the size of impacting particle and sometimes becomes zero by using particle size of the range of 2 µm [13]. Miyazaki et al. [14] revealed that fiber-reinforced polymers (FRPs) having treated fibers exhibits better resistance against erosion than non-treated fibers because of higher interfacial strength between matrix and reinforcement. The angle of impingement significantly affects the erosion rate of the composite surface. Rajesh et al. [15] revealed that the impact of an abrasive particle at an oblique angle (30 • ) is much more influencing than the normal impact angle (90 • ). The optimization of process parameters for tribological behavior has been performed by various scientists using several techniques like the Taguchi's methodology [16], response surface methodology [17], artificial neural network [18], genetic algorithm [19], etc. Response surface methodology (RSM) is employed as an optimization tool for the modeling and optimization of single as well as multi-objective optimization [20]. In recent times, several r...
