Development of a Vibration Device for Grinding with Microvibration
This study aimed to develop a device to facilitate grinding experiments with microvibration for analyzing the vibration effect on surface finish of ground surfaces. A microvibration device was designed and fabricated. It can be used to provide microvibration to the workpiece vertically and/or horizontally during grinding. The relationship of the driving voltage, vibration displacement, and freq...
متن کاملGrinding Wheel Loading with and without Vibration Assistance
Introduction Due to its tool structure and composition, the grinding operation is considered the best machining process in the manufacture of brittle materials like ceramics. A grinding wheel distributes wear over many cutters and is capable of replenishing itself. However, the condition of the grinding wheel constantly changes as grits wear and chips accumulate in the spaces between grits. The...
متن کاملThe roles of vibration amplitude and static force
Previous work (Verrillo, 1963, 1968) has shown that when measured as a change in absolute threshold, spatial summation occurs only at vibration frequencies above 40 Hz. The present study measured vibrotactile spatial summation at suprathreshold amplitudes. A matchingtask was used to investig-ate the effect of varying contactor size on sensory magnitude at three different vibration frequencies. ...
متن کاملOxygen uptake in whole-body vibration exercise: influence of vibration frequency, amplitude, and external load.
Vibration exercise (VbX) is a new type of physical training to increase muscle power. The present study was designed to assess the influence of whole-body VbX on metabolic power. Specific oxygen uptake (sVO(2)) was assessed, testing the hypotheses that sVO(2) increases with the frequency of vibration (tested in 10 males) and with the amplitude (tested in 8 males), and that the VbX-related incre...
متن کاملVibration of low amplitude imaged in amplitude and phase by sideband versus carrier correlation digital holography.
Sideband holography can be used to get field images (E0 and E1) of a vibrating object for both the carrier (E0) and the sideband (E1) frequency with respect to vibration. Here we propose to record E0 and E1 sequentially and to image the product E1E0* or the correlation 〈E1E0*〉. We show that these quantities are insensitive to the phase related to the object roughness and directly reflect the ph...
