“…Synchronized and transient measurements revealed the discrete nature of the ECDM process [4]. While investigation of experiments revealed that the sparking occurs at the tool electrode interface [5]. It is important to study the wettability and machining characteristics of different tool electrode materials and their impact on gas film formation and also their machining performance [6].…”

Electro Chemical Discharge Machining Process (ECDM) is a prominent hybrid machining process used in distinctness machining of hard and brittle non-conducting materials. ECDM has been exploited to fabricate micro-holes in non-conductive brittle materials. An experiment has been conducted on ECDM for micro drilling operation on borosilicate glass material according to the Taguchi Orthogonal Array (L9) technique in order to ascertain the effect of certain variables in the same manner with material removal rate (MRR) & tool wear rate (TWR). In superintending the machining performance, signal to noise ratio (S/N ratio) was calculated to find out the involvement in the main machining variables, such as applied voltage, electrolyte concentration and inter electrode gap. During the experiments, the nonconducting and highly brittle borosilicate glass material is used as a work-piece and NaOH as electrolyte solution. In addition to that, Graphite and Tungsten were used as cathode and anode respectively. In this research of Taguchi method was utilized to optimize the process variables which affect MRR and TWR. From main effect plot through Minitab software, it turns out that the inter-electrode gap has the supreme affect on MRR and TWR.

Abstract:The paper presents analysis of influence of parameters and conditions of grinding process using diamond grinding wheels with ceramic bond (Ba23 bis, W1) on the geometrical structure and quality of machined cemented carbides (H10S) and composite materials (BNDCC). During performed analyses there was calculated the material removal rate Qw, specific material removal rate Q'w and G coefficient. There was performed comparative analyses of achieved results for various materials. There is also presented influence of machining conditions on the material removal process efficiency and quality of surface after machining of composite materials (DDCC and BNDCC) when using non-conventional machining processes: electrodischarge wire cutting (WEDM), electrochemical machining with rotating tool electrode (RECM) and hybrid process of electrochemical-electrodischarge machining with rotating tool (R-ECDM) with grinding wheel and metal disk as the tool electrode.
