“…Meanwhile, the thrust force and torque values were significantly increased when the feed rate was increased as shown in Fig. 15 (Rahim & Sasahara, 2011). The thrust force and torque are strongly correlated with the chip thickness, which is associated with the feed rate (Liao et al, 2007). This is because high feed rate results in a larger cross sectional area of the undeformed chip, and, consequently, greater thrust force and torque are produced.…”

“… Conventional deep micro-hole mechanical drilling of Inconel ® 718 is a time consuming process. A noticeable improvement in terms of circularity was observed and 50% increase of MRR was reported, while using the hybrid process combing mechanical drilling with laser and ultrasonic vibration, respectively (Okasha et al, 2010;Liao et al, 2007).  On the other hand, recast layer and spatter cannot be completely eliminated if an individual laser drilling process is used.…”

“…By continuous frequency vibration of cutting tools during drilling operations, the quality of the deep micro-holes can be significantly improved. Azarhoushang and Akbari (2007) developed a drilling tool with high frequency and low amplitude ultrasonic oscillation for the drilling of Inconel ® 738-LC, which showed a noticeable improvement in terms of average surface roughness and circularity, but, Liao et al (2007) argued that the vibration amplitude of more than 12 µm is likely to result in negative effects, such as reducing tool life. Heisel et al (2008) and Potthast et al (2008) designed a piezoelectric actuator and a piezoelectric transducer, which was used for deep hole drilling of electrolytic copper.…”

Today, hybrid manufacturing technology has drawn significant interests from both academia and industry due to the capability to make products in a more efficient and productive way. Although there is no specific consensus on the definition of the term 'hybrid processes', researchers have explored a number of approaches to combine different manufacturing processes with the similar objectives of improving surface integrity, increasing material removal rate, reducing tool wear, reducing production time and extending application areas. Thus, hybrid processes open up new opportunities and applications for manufacturing various components which are not able to be produced economically by processes on their own. This review paper starts with the classification of current manufacturing processes based on processes being defined as additive, subtractive, transformative, joining and dividing. Definitions of hybrid processes from other researchers in the literature are then introduced. The major part of this paper reviews existing hybrid processes reported over the past two decades. Finally, this paper attempts to propose possible definitions of hybrid processes along with the authors' classification, followed by discussion of their developments, limitations and future research needs.

“…Several researchers (Liao, et al, 2007, Zhang, et al, 2014, Suzuki, et al, 2011, Nambu, et al, 2011, and Liu, et al, 2012 have shown that ultrasonic vibration-assisted machining resulted in the reduction of the cutting force, the improvement of the machined surface, and the extension of the tool life in the drilling of steel, Inconel, tungsten carbide and composite materials. In a previous study, the authors proposed an ultrasonic vibration-assisted helical milling method, and evaluated the effects of the grinding parameters on surface chipping (Noma, et al, 2014).…”

This paper deals with axial ultrasonic vibration-assisted machining with workpiece bending. It was proposed as a novel machining method for the reduction of the chippings at the machined holes during micro through-hole drilling of chemically strengthened glass. In micro through-hole drilling of chemically strengthened glass, machining accuracy and efficiency tend to be low because the material's high hardness and brittleness cause rapid tool wear and large chippings at the inlet and outlet of the machined holes. In order to machine small holes with high accuracy, the reduction of the tensile stress that causes large chippings at the outlet of the machined holes is an issue of primary importance that deserves investigation. In the proposed machining method, the glass plate is bent slightly to be convex upward through the application of a compressive stress at the posterior surface of chemically strengthened glass, with a specially designed jig. Using this proposed method that can reduce the tensile stress, the chipping size at the outlet of the machined holes was successfully reduced with applied compressive stress values of 38.9 MPa. In conclusion, it has been clear that the axial ultrasonic vibration-assisted machining with workpiece bending has the potential for achieving high-precision and high-efficiency machining for chemically strengthened glass.
