A thin, solid-state hemispherical shell is used to fabricate the HRG, which is anchored by a thick stem. In the present study a mesoscale model of HRG was fabricated. The fabricated device is tested using a noncontact approach to measure its natural frequencies and drive and sense directions. Finite element analysis was carried out using commercial software COMSOL multiphysics to validate the experimentally obtained frequencies of the gyroscope. Numerically obtained drive and sense mode frequencies were found to be within 8% of the measured values.

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...

In new age, the technology is continually becoming more advance exponentially. The advanced materials are required in many technological fields. In manufacturing many engineering components, there is requirement of materials which has high strength at high temperature, good resistance to chemical degradation, good resistance to wear and having low density. Advanced materials such as superalloys and metal matrix composites satisfy these requirements. But machining of these materials with conventional machining is difficult and sometimes impossible task. Unconventional machining processes (UMPs) such as electric discharge machining, electrochemical machining, ultrasonic machining, laser beam machining, electron beam machining etc have been developed by people to machine these materials. The performance of these AMPs can further be enhanced by hybridizing it with other...

The selection of suitable material plays an important role in product development for customer satisfaction. Due to wrong selection of material, increase the cost of the product as well as product failure. A better method is more important for selection of material. Due to increasing scenario in the manufacturing of automotive parts, there should be the selection of best material for manufacturing of automotive parts. In this present work, there is a selection of Mg Alloy in the automobile industry. For the proper selection of Mg alloy a TOPSIS, COPRAS, MOORA, ELECTRE and SAW Method is applied and then finally ranked the best magnesium alloy. In this proposed research work, five Method is compromised and select the best Mg alloy

In this study, the design of experiment which is a powerful tool for experimental design is used to optimize the machining parameters for effective machining of the work piece. Interfacial temperatures play an important role in the machining of AISI 1045 steel. It is increasingly important to understand how the machining temperatures are affected by cutting speed, feed rate and tool wear. Also, the tool wear is related to the cutting forces. Experiments conducted involve simultaneous measurement of cutting forces and temperature using a dynamometer and an infrared camera to monitor the temperature at the toolwork piece interface. The results from the experiment are analyzed by design of experiment methods, namely ANOVA, Regression analysis and Response surface methodology.
