Optimization of Process Parameters in EDM
Abstract: Extensive research has been done till date to improve the performance of electrical discharge machining (EDM). In the past few years, the Taguchi method has played an important role in the optimization of process parameters. However, many of the studies have focused on static or single-quality characteristics such as smaller-is-better, larger-is-better, and nominal-is-best. The Taguchi method is best suitable for relative analysis. The prime drawback here to mention is that …

Investigations on Piezoactuator-Based Active Vibration Isolation for Tool-Based Micromachining Applications
Abstract: Stacked piezoactuators are suitable actuators for active vibration isolation systems due to their high stiffness and fast response. However, they exhibit hysteresis nonlinearity between applied voltage and the resulting displacement. In this paper, Bouc-Wen model is used to model the hysteresis nonlinearity of stacked piezoactuator. The model parameters are estimated from the experimental voltage-displacement data of a stacked piezoactuator using “Trust-region nonlinear least square method” in MATLAB Simulink. The resulting …

Emissivity and Dielectric Behavior of Red Soils of Dhule District at X-band Microwave Frequencies
Abstract: Using X-band (8.2 and 10.5GHz) experimentation, the fluctuation of the dielectric constant (ε’) and dielectric loss (ε’’) of soil samples with different moisture contents has been determined. After reaching a transition point, the value of (ε') grows gradually with moisture content before increasing quickly after that. The emissivity has been estimated from experimentally determined (ε’) using emissivity model for vertical polarization. The findings indicate that as MC/dielectric constant increases, emissivity …

Correlating the Damage Behaviour of Polymer Composites with the Potential Energy of the Impactor
Abstract: Design of structures using composites requires comprehensive evaluation and characterization of mechanical properties in both undamaged and damaged state. Composite laminates undergo combinations of mechanical loading resulting into microdamage accumulation in the plies. The first mode of damage is usually intralaminar cracking with the crack plane transverse to the middle plane of the laminate, spanning the whole width of the laminate. The density of cracks in a ply depends on …
