A Theoretical analysis on Electro Chemical Discharge Machining using Taguchi Method

Abstract

The Electrochemical discharge machining (ECDM) is a growing machining process that develops from the processes like electrochemical machining (ECM) and electric discharge machining (EDM), used in micro machining of usually non-conductive materials such as quartz, glass, composites and ceramics. In recently time the need of non-conductive materials has been grown rapidly in the field of aerospace, medical, electrical and optical applications. Such as these applications implicate machining with higher reliability and higher accuracy, ECDM process has lavish scope in this area. Some further methods also that can machine non-conductive materials but they have certain limitations. In the current time ECDM is an emerging process, continuously researchers are trying to improve and amend it as a better way for non-conducting materials. Currently this paper carried out a study on continuous improvements in ECDM in machining of glass in the ECDM, has been show their effect on material removal (MR). A Taguchi analysis on machining of borosilicate glass has also been obtained, wherein it is illustrated that increase in feed rate and electrolyte concentration increases the MR.

Biomass-derived graphene modified γ-Fe2O3/N,Fe–TiO2@GO: a prolific photoactive material with extended visible to near IR harvesting

“…† Further to that, a probability value less than 0.005 indicates the significance of the quadratic model terms. 43 As a result, the developed framework can be used to anticipate the photocatalytic degradation of mixed disperse dyes using the catalyst γ-Fe 2 O 3 /N,Fe-TiO 2 @1.5%GO on a massive level.…”

Optimasi Kekasaran Permukaan Baja AISI H13 pada Proses Permesinan Elektro Kimia Skala Laboratorium dengan Metode Taguchi

“…Faktor utama yang mempengaruhi laju permesinan dan kualitas akhir benda kerja adalah konsentrasi elektrolit, tegangan, celah antar-elektroda, dan sebagainya. Geometri, kondisi, dan akurasi permukaan permesinan juga dipengaruhi oleh parameter tersebut [2]. Guna mendapatkan kekasaran permukaan yang minimal merupakan suatu tantangan dan menjadi kendala tersendiri bagi operator.…”

Parametric Appraisal of Electrochemical Machining of AISI 4140 Chromoly steel using Hybrid Taguchi - WASPAS - Sunflower optimization algorithm

“…Although there is the possibility of boosting the study's dependability, the reliance on regularity in several aspects needs thorough research to discover the source and influence of the numerous parameters [3]. The electrochemical (electrolysis) activity removes the metal, resulting in diminished surface roughness, residual stress, and higher precision [4][5][6]. Furthermore, little or minimal thermal or mechanical strains will be generated, but sparks will be generated due to the low working temperature, which must be eliminated so as to minimise tool wear [5].…”

“…Because it can manufacture all types of hard, complex-shaped, yet conducting substances with excellent surface quality, ECM is a widely popular and accepted non-conventional machining technology in current manufacturing sectors [6]. Many precision sectors, such as aerospace, tool and die production, and defence, use ECM.…”
