vibration cutting (vc), elliptical vibration cutting (evc) and ordinary cutting (oc) of in738 work-pieces have been experimentally investigated in the present research. the experiments were carried out by using single crystal diamond tool and ultra-precision cnc lathe. vibration frequency is 36.16khz and the amplitude is . the influence of various cutting parameters including cutting speed, fee...

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...

In order to improve the traditional methods of procyanidins extracting, ultrasonic-assisted filtration was used in the process of extracting proan-thocyanidin which was from membrane concentration of grape seed. Through the mechanism analysis of ultrasonic-assisted ultrafiltration, ultrasonic is able to alleviate the phenomenon of concentration polari-zation, so the efficiency of extracting pro...

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. ...
