摘要
Taper cutting, a typical application of Wire Electro Discharge Machining process is widely used to produce parts with complex geometry such as cutting and extrusion dies, which finds wide application in tool and die making industry. Taper angle becomes a vital process parameter during taper cutting and is a critical performance measure for the tool and die making industry. The present investigation is initiated with a thought to optimize the different process parameters such as pulse on time (Ton), wire tension (WT), wire feed rate (WFR), taper angle (TA) on the performance measures namely taper error (TE), material removal rate (MRR) and surface roughness (SR) during taper cutting operation utilizing WEDM. Experiments were conducted using Taguchi's L9 (34) orthogonal array on En-31 tool steel work material using brass wire of 0.25 mm diameter, as electrode material. The parametric multi-objective optimization of the experimental results has been carried out using Taguchi based Grey Relational Analysis (TGRA). The analyzed results uncovers that the pulse on time is the utmost prompting factor for MRR and SR while the taper angle cut on the work material turn out to be a significant factor for taper error.
