Research paper thumbnail of Extension of Wire-EDM Capability for Turning Titanium Alloy and an Experimental Study for Process Optimization by Grey Relational Analysis

As a non-conventional technique, Wire-EDM is considered as efficient and economical tool in machining of electrically conductive advanced alloys and composites. As the job rotational axis is not available in the machine to perform turning operations, thus the Wire-EDM is assembled with suitably designed and manufactured rotary mechanism with maintained runout accuracy of 15 micron. The independently controlled process parameters are rotational speed of workpiece (RPM), pulse-on time (T on) and wire feed rate (WF). Whereas, the performance parameters are material removal rate (MRR) and average surface roughness (R a) which indicates the productivity & part quality respectively. Ti-6Al-4V alloy is selected as workpiece material. Mixed taguchi 2 1 x3 2 orthogonal array is selected to design the experimentation. Grey Relational Analysis (GRA) has been implemented for simultaneous optimization to get higher value of MRR and lower value of R a. The optimized process parameter values are RPM: 75 rpm, T on : 10 μs and WF: 14 m/s which gives 16 % of significant improvement in surface quality and 1% of improvement in material removal.

This research aims to calculate the mechanical properties of the Al@Al2O3 composites by varying alumina nanoparticles (Al2O3 NPs) content using a non-invasive, position sensing detector (PSD) unit-based optical method. The composite was prepared by a powder metallurgy technique, and its characterization was conducted using SEM and XRD to understand its surface morphology and microstructure. The natural frequency and Young’s modulus of the composite were estimated experimentally. Young’s modulus was calculated using this natural frequency. The proposed study shows that Young’s modulus of the composite increases with an increase in Al2O3 NPs content in the composition, irrespective of the testing method. Along with this, natural frequency also increases with the increase in the Al2O3 NPs content. Evaluated propertie...
