Experimental Investigation on Machining Characteristics of EN19 Alloy Steel Using CNC Vertical Machining Center
Abstract: In this research work, the detailed experimentation investigation was performed for EN19 steel using milling process on CNC VMC. The experimentation strategy has been planned using Taguchi’s L9 orthogonal array, consisting of three process parameters such as cutting speed, feed rate and depth of cut on material removal rate (MRR) and surface roughness (SR). Two different types of end mill cutters (solid carbide and titanium nitride coated carbide end mill) …

Preparation and Characterization of a Novel Lignocellulosic Fiber from Calotropis gigantea Stem Fiber for Thermoplastic Composites
Abstract: In the current article, Calotropis gigantea fiber mat (CGM)/thermoplastic polypropylene (PP) strengthened non-woven unidirectional composites were successfully manufactured by hot compression molding using the film piling method. Micromechanical and physicomechanical properties such as tensile, flexural, compressive, impact properties, thickness, swelling, and water absorption of CGM/PP composites were evaluated for the effects of CGF composition, mercerization of CGF as well as the inclusion of two types of coupling agents (vinyltriethoxysilane and …

Effect of Drilling Process Parameters on Surface Roughness of LM6/B4C/Fly Ash Hybrid Composites
Abstract: This research seeks to assess the effect of process variables such as feed rate (FR), spindle speed (SS), drill material (DM) and reinforcement (R%) on surface roughness (SR) when drilling LM6/B4C/Fly ash hybrid composites. The stir casting process was used to fabricate the LM6/B4C/Flyash hybrid composites utilizing LM6 aluminum alloy as the matrix material and B4C/Fly ash as strengthening materials. Experiments were carried out using an L18 orthogonal array (OA) …

Drilling Parameters Optimization in LM6/B4C/Fly ash Hybrid Composites by Taguchi Technique
Abstract: Aluminium matrix composites (AMCs) are challenging to machine due to its abrasive characteristics. Because of the broad adoption of MMCs, it is vital to create sufficient equipment to facilitate efficient manufacturing. The current study utilizes signal-to-noise ratio (S/N) analysis to determine the ideal machining parameters for drilling AMC’s. The goal with this study is to investigate the effect of feed rate (FR), drill type (D), speed (SS), reinforcing material R …

Three Stage High Step-up Interleaved Boost Converter with Voltage Multiplier Cell
Abstract: In this paper, three stage high step-up interleaved boost converter with three voltage multiplier cells (VMCS) and three state switching cells (3SSC) is proposed. Here an interleaved boost converter is used, as a result higher efficiency and reduced input ripple current is obtained. Also, an additional stage of voltage multiplier i.e., three stages is added so that voltage gain will increase. It reduces switching loss and stress through the devices. …
