“…A unique feature of this method is a charge-coupled device (CCD) camera, vertically mounted above the burr specimen which can capture the entire side surfaces of the drilling burr. Burr size is measured through image-processing software by calculating the number of black pixels in the captured image in [33]. This shadingarea method can be employed as a simple and feasible approach for the analysis of burrs in intersecting holes, for example in valve manufacturing.…”

“…The machined surface quality measurement revealed that the effect was greater when feeddirectional vibration was applied to the material than when the vibration was applied across or perpendicular to the feed, since the latter resulted in the formation of wavy burrs. The level of surface roughness is dependent on a combination of factors including feedrate and tool profile, in addition to vibration and tool speed, so in order to obtain better machined surface the vibration machining parameters should be optimized [59,[80][81][82]. Ding et al [83] found that feed per tooth has a significant effect on the height of the top burr, and the use of vibration-assisted cutting in micro end milling could minimize the size effect and improve the cutting performance, thereby reducing the height of the top burr by 80%.…”

Vibration-assisted machining (VAM) is an external energy assisted machining method to improve the material removal process by superimposing high frequency and small amplitude vibration onto tool or workpiece motion. VAM has been applied to several machining processes, including turning, drilling, grinding, and more recently milling, for the processing of hard-to-machine materials. This paper gives a critical review of vibration-assisted milling (VAMilling) research. The basic kinematic equations of 1D and 2D VAMilling are formulated and three typical tool-workpiece separation types are proposed. State-of-the-art on the principle and structural design of VAM systems are reviewed. The benefits and applications of VAMilling are discussed with emphasis on machining of hard-to-machine materials. Finally, the paper concludes with future possibilities for VAMilling.

“…The allowed feed rate of cutting is increased because vibration reduces the cutting and friction forces reducing heat generation and chatter. Another benefit to vibration cutting is an improved surface finish [24][25][26][27]. Vibrational machining methods such as vibration-assisted nanoimpact machining by loose abrasives have proven to be an effective method of performing targeted machining of hard and brittle materials [28].…”

This work investigates the performance of a novel compliant needle for cutting tissue. The novel cutting geometry transfers axial vibration to transverse motion at the tip. The cutting edge of the geometry is defined in terms of the time-dependent inclination and rake angle. Finite element analysis was performed to determine the compliant geometry effect on the axial vibration modes of the needles. An ultrasonic transducer is used to apply the axial vibration. An ultrasonic horn was developed to increase the amplitude of vibration. Experiments were performed to determine the effectiveness of the compliant needle geometry. The motion of the compliant needle is measured with a stereomicroscope. The two compliant geometries developed transverse motion of 4.5 μm and 16.0 μm. The control needle with fixed geometry developed no measured transverse motion. The insertion force was recorded for two different compliant geometries and a control geometry inserted into a polyurethane sheet. The puncture force of the control needle with applied vibration and the two compliant needles was up to 29.5% lower than the control insertion without applied vibration. The compliant needles reduced the friction force up to 71.0%. The significant reduction of the friction force is explained by the compliant needles' ability to create a larger crack in the material because of their transverse motion.
