Opis:: In this research work, the Ti-6Al-4V material was used for the investigation of machining parameters by means of hybrid micro electrical discharge machining to improve the machining process and reduce the negative effects of debris accumulation in the drilled hole. L9 orthogonal array was used in the Taguchi based grey relational analysis to optimize the parameters such as material removal rate and diametrical accuracy of the machining process for Ti-6Al-4V. This work encompasses the design, development, and calibration of the work piece vibration platform and experimental analysis of the process parameters by means of the hybrid micro electrical discharge machining process. The maximum material removal rate and minimum surface roughness was observed at the current value of 2.5 A, pulse on time is 2 μs and pulse off time is 14.5 μs. The maximum material removal rate was observed for the increase in pulse on time with 14.4 μs and 4 A current level. The diametrical accuracy of the microholes was increased while increasing the pulse off time and decreasing the pulse on time. The fluid flow simulation has been conducted to find out the pressure drop and to know the velocity of the flow inside the hole for the effective flushing of the debris during machining.

Opis:: Spur gears are the most well-known kind of gears used in hybrid vehicle’s power transmission. They have straight teeth, and are mounted on parallel shafts. In some cases, many spur gears are utilized without a moment's delay to make huge rigging decreases. In this paper how stress creates on a spur equip under various conditions and conditions and reenactments of a rigging system (two spur gears) is assessed by Ansys workbench. For this static structural and dynamic analysis modeling is utilized. A couple of spurs equip tooth in real life is by and large subjected to two sorts of cyclic stress: contact stress and twisting stress including bowing fatigue. The two stresses may not accomplish their greatest esteems at a similar purpose of contact fatigue. These sorts of failure can be limited by analysis of the issue amid the outline organize and making appropriate tooth surface profile with legitimate assembling strategies.

Opis:: Execution of customized Start/stop (SS) advancement in a medium vehicle is a fiscally canny way to deal with improves mileage and rot surges without influencing purchaser request. In urban degrees, where an unbelievable bit of the vehicle driving time is spent sitting at stop lights, the motor can be closed down so spare fuel. The motor is quickly and carefully restarted as the driver quickens it. This working strategy is a significant part of the time utilized as a bit of full small-scale half breed electric vehicles that have fantastic power sparing potential. In this paper the framework is introduced in a Three-Wheeler where the regenerative braking and Stop-Start strategy of the Micro Hybrid structure is worked by Ultra-capacitor alongside Traditional battery. The power conveyance and investigation of vehicle is appeared in paper which was finished by MATLAB. An attainability investigation for Bangladesh is likewise led in this paper.

Opis:: The paper focuses on machining difficult-to-cut materials where a significant component is titanium. The paper discusses a complex process of electrochemical grinding (ECG). A practical example was given by discussing the results of ECG. Selected difficult-to-cut materials, along with their typical ECG properties, were compared. In addition, the paper discusses the phenomenon of micro short-circuits constituting a form of an interference characteristic for the process. The results presented in the paper refer to the phenomenon of a micro short-circuits, i.e. the case when a rapid and uncontrolled electrical discharge occurs in the machining zone. The paper presents examples of recorded micro short-circuits and attempts a time-frequency analysis regarding the occurrence of the disturbance. To reveal the dynamics of the ECG process we applied wavelet analysis.

Opis:: The current study presents an analytical model for a MEMS cantilever based hybrid thermo- -piezoelectric micro actuator. The micro actuator structure consists of a unimorph type bending piezoelectric beam and a passive layer which uses the thermal bimorph principle. Primarily, under electrical and thermal loadings, the governing equations of motion are derived. After verification of the results, the deflection analysis of the micro actuator is performed. Moreover, the equivalent force at the actuator tip is obtained. To provide efficient optimization, the effects of the micro actuator geometrical and materials properties on the actuator tip deflection and force are investigated.
