“…9, has also been called ultrasonic drilling, ultrasonic abrasive machining, ultrasonic cutting, ultrasonic dimensional machining, and slurry drilling (Thoe et al, 1998). In this process, low-frequency electrical energy is converted to a high-frequency electrical signal which is converted into mechanical vibrations by a transducer (Perkins, 1972;Scab, 1990;Thoe et al, 1998). This causes the tool to vibrate along its longitudinal axis at high frequency (usually ≥ 20 kHz) with an amplitude of 5-50 μm (Kennedy and Grieve, 1975;Thoe et al, 1998).…”

Titanium and its alloys (Ti) are attractive for many applications due to their superior properties.However, they are regarded as hard-to-machine materials. Drilling is an important machining process since it is involved in nearly all Ti applications. It is desirable to develop cost-effective drilling processes for Ti and/or improve the cost-effectiveness of currently-available processes. Such development and improvement will be benefited by a comprehensive literature review of drilling processes for Ti. This paper presents a literature review on mechanical drilling processes for Ti, namely, twist drilling, vibration assisted twist drilling, ultrasonic machining, and rotary ultrasonic machining. It discusses cutting force, cutting temperature, tool wear and tool life, hole quality (diameter and cylindricity, surface roughness, and burr), and chip type when drilling of Ti using these processes.

“…This electrical signal is supplied to the transducer for conversion into longitudinal or transverse low amplitude mechanical vibrations (Thoe et al, 1998). Electric energy supplied by the ultrasonic generator is converted to high-frequency vibratory energy (20-60 kHz for the applications reviewed) by the transducer, a piezoelectric stack.…”

“…This abrasive slurry is thought to propagate further material removal by material microchipping for industrial ultrasonic applications (Thoe et al, 1998;Moreland, 1984). It is possible that a similar mechanism occurs for harder biological tissue, although this has not been investigated.…”

“…These mechanisms include mechanical abrasion by direct hammering of abrasive particles against the tool surface, microchipping by impact of free-moving abrasive particles and cavitation effects from the abrasive slurry (Thoe et al, 1998). Their combined effect results in shear, fracture and material removal from the surface.…”

Ab s t r a c t High-power low-frequency ultrasound in the range 20-60 kHz has wide ranging clinical applications in surgical and medical instruments for biological tissue cutting, ablation or fragmentation, and removal. Despite widespread clinical application and common device operating characteristics, there is an incomplete understanding of the mechanism of tissue failure, removal and damage. The relative contribution of cavitation, direct mechanical impact and thermal effects to each process for specific tissue types remains unclear. Different and distinct mechanisms and rates of tissue removal are observed for interaction with soft and hard tissue types. Device operating parameters known to affect the interaction include frequency, peak-peak tip amplitude, suction and application time. To date, there has been little analysis of the effect of variations in, and interactions of, these parameters on tissue removal and damage for individual biological tissue types. Potential controllable damage mechanisms occurring in tissues include alteration in global biomechanical properties, histomorphological changes, protein denaturation and tissue necrosis. This paper presents a critical review of the literature on the clinical application, mechanism of tissue interaction, removal and residual tissue damage. It describes known mechanisms for distinct tissue types.
