Due to continuous tool engagement, turning processes tend form long chips when machining ductile materials. These chip shapes have a negative influence on process performance and productivity. One approach improve breakage is superimposition of vibrations in feed direction the process, which leads modulation uncut thickness. In joint industrial project with Schaeffler Technologies AG & Co. ...

Abstract In this article, the comprehensive review on application, and indeed, a comparative analysis dry machining of different types materials (Inconel, steel, aluminum, cast iron, magnesium advanced materials) used in (turning, drilling milling operations) were carried out light utmost works published literature. The work describes scientific findings past twenty years, including sustainable...

To improve the machining performance of different processing materials, a three-excitation ultrasonic spatial vibration-assisted turning system is proposed, which realizes non-unity plane where cutting trajectory tool located. The influence and formation law on surface roughness workpiece under vibration parameters (amplitude) (cutting speed, depth, feed) were analyzed by response methodology. ...

In this research, finite element analysis of the conventional drilling and vibration assisted drilling is carried out. The ABAQUS software is employed for FE analysis. The Johnson-Cook models for both plastic deformation and damage are employed for FE simulation.The results of the FE analysis are then verified with experimental results in both conventional and vibration assisted drilling on Al ...

Deciding the numerous parameters involved in designing a competent artificial neural network is a complicated task. The existence of several options for selecting an appropriate architecture for neural network adds to this complexity, especially when different applications of heterogeneous natures are concerned. Two completely different applications in engineering and medical science were selec...

In this study, diamond turning of an aluminiumbased metal matrix composite (MMC) reinforced with SiC particles was conducted with the assistance of ultrasonic vibrations. A simple and small size vibration device was designed to mount a piezoelectric transducer and a diamond insert onto a CNC machine. Turning experiments were carried out using a factorial design to investigate the effects of vib...

According to turning instead of grinding process requirements and traditional working principle of ultrasonic vibration turning, a new idea of imitating grinding of two-dimensional ultrasonic vibration turning is brought firstly, and the mechanism of two-dimens ional ultrasonic vibration turning is elaborated. Based on the MATLAB software, grinding trajectory simulation and honing trajectory si...
