“…This technique could be used to machine and analyze many kinds of industrial materials, including ultra-hard materials [11][12][13]. In future work, we will utilize this system to obtain important information about the internal structural features, including inclusions, defects, and cracks, of a wide variety of industrial materials.…”

“…Ultrasonic vibration cutting techniques have been proposed to decrease tool wear and to produce mirrored surfaces without polishing. Shamoto and Moriwaki [11][12][13] developed an ultrasonic elliptical vibration cutting system. The elliptical vibration reduces contact time and friction between the tool and the work material in a cutting process.…”

Abstract:For three-dimensional observation of the internal structure of hard materials, we developed an automated system based on serial sectioning with precision cutting and optical microscopy. The elliptical vibration cutting device in the system created mirrored surfaces suitable for optical microscopy during the serial sectioning of steel materials. In this study, high-speed sectioning with several micron thickness and repeated precise machining to depths of up to around 1 mm were achieved with a flat-edge cutting tool. For a 3 × 3 mm area of bearing steel, a mirrored surface could be created in about 1 minute, and 400 serial sectioning images were obtained within 7 hours without additional machining processes such as cleaning or changing of tools. The three-dimensional shapes and positions of continuously distributed inclusions found deep within the bearing steels, as well as cracks originating from these inclusions, could be detected with resolutions as high as 80 × 80 nm and in a wide field of view using this system.

“…Contact friction between tool and work-piece is believed to transform into quasi-viscous friction in presence of ultrasonic vibration [5]. Shamoto [6,7] and Babitsky [8,9] early works demonstrated the capabilities of the technique and pawed the way for a widespread adoption of ultrasonically-assisted machining. Several researchers reported advantages in ultrasonically-assisted machining when comparing results with similar conventional techniques.…”

Abstract:The effects of frequency in ultrasonic vibration assisted milling (UVAM) with axial vibration of the cutter is investigated in this paper. A series of face-mill experiment in dry conditions were conducted on AISI 316L, an alloy of widespread use in industry. The finished surfaces roughness were studied along with basic considerations on tool wear for both conventional milling and an array of frequencies for UVAM in a wide range of cutting conditions. Surface residual stresses and cross-cut metallographic slides were used to investigate the hidden effects of UVAM.Experimental results showed competitive results for both surface roughness and residual stress in UVAM when compared with conventional milling especially in the low range of frequency with similar trend for tool wear.

“…Moriwaki et al also developed an elliptical vibration milling system which aligns the tool spindle slightly off the rotating axis of the servo motor. 7 Since they used a vibration frequency of 167 Hz, the maximum spindle rotation frequency was set at 1,500 RPM so that the vibration frequency would be much higher than the spindle rotation frequency. They have demonstrated that cutting forces and tool wear are reduced during the designed milling process under low cutting speed.…”
