“…However, (Aoki and Nishimura, 2004) oppose the claim and stated that in glass fibre-reinforced plastics (GFRP), the surface roughness increases in case of UAD. Application of UAD on metal matrix (AL/SiC) composite showed no change in surface roughness with or without the application of vibration on the tool (Liu et al, 2005).…”

Carbon fibre-reinforced plastics (CFRPs) gained substantial acclaim in recent decades and are used in aerospace, automotive and structural applications due to their high strength-to-weight ratio, high stiffness, high fatigue and corrosion resistance. CFRPs are manufactured near to net shape but some machining processes such as drilling cannot be avoided. Drilling induces damage (delamination, matrix cracking, matrix burning, lamina cracking and fibre pull out) in CFRP because of high axial thrust forces and a temperature rise. In this research an attempt is made to use ultrasonically assisted drilling (UAD) to reduce the axial thrust forces. In UAD high frequency (~ 20 kHz) vibrations are superimposed on a drill bit, preferably in axial direction, to reduce the thrust forces. In this study, experiments are conducted in two stages. At the first stage an initial setup with an existing UAD transducer is used to compare UAD with conventional drilling (CD) of CFRP. A reduced thrust force is experienced in case of UAD when compared to CD. At the second stage, drilling dynamics, i.e. feed speed, is changed along with the improvement of the transducer, and an enormous amount of force reduction (>80%) is observed in case of UAD (as compared to CD).

“…Ultrasonic cleaning [2], forming [3], peening [4], casting [5] are only a few common industrial applications of this kind of technology. Nowadays, ultrasonic vibration is applied as an assisting process for traditional machining operations such as turning, drilling and milling leading to highest productivity and performance in all manufacturing operations, especially for machining of those hard-to-cut materials [6][7][8][9][10].…”

A recent and promising technique in advanced material processing techniques is the use of ultrasonic assistance in almost all cutting, forming and shaping processes. Optimizing manufacturing costs through reducing process forces and tool wears, improving machinability through enhancing surface finish and quality with minimal production time and energy, and delivering products with prolonged service life are some of the most important features of the vibration assisted manufacturing methods.To study the effect of ultrasonic vibrations on the milling process of the stainless steels, a series of experiments was designed and then implemented on a difficult-to-machine material. The result of the surface roughness and the cutting force tests has been comprised with and without processing by ultrasonic assistance. Experiments prove that under ultrasonic assistance, cutting forces are reduced, surface quality is improved and in all, a better machinability is achieved. It is concluded that dry aero-acoustical lubrication conditions and materials softening are of crucial importance in the machinability of difficult-to-cut AISI 304 materials.

Needle vibration tissue cutting is a method that has been shown to reduce tissue cutting force and thereby improve needle position accuracy inside the body. Needle accuracy is crucial for minimally invasive needle operations such as the radiation cancer treatment of brachytherapy. This article uniquely determines the importance of needle geometry in minimizing cutting force in needle vibration tissue cutting. This article also determines how vibration specifically affects cutting force. This new information was found by performing needle cutting experiments with five varying conical tipped needles being inserted into ex vivo bovine liver as well as a polyurethane sheet at varying vibratory amplitudes and frequencies. Results show that applying vibration to sharper needles greatly reduced the insertion force by up to 67%, where the blunter needles saw diminishing benefits. The tissue phantom experiments showed that vibration reduced the force needed to propagate the created crack but showed no improvement over the initial puncture force. This greater understanding of needle vibration tissue cutting can lead to improved needle geometry designs that work with vibration to reduce tissue cutting force.
