“…An experimental investigation done on K9 glass shows that intermittent RUM can lead to reduction in the size of edge chipping while comparing with continuous RUM. This relationship is close to linear [8].Shape of the tool also plays a significant role in reducing the edge chipping size. An investigation of tool shape has been done on edge chipping in RUM and it is seen that the tool face surface's slope if modified from 0 to 30 degree, cause a drop in the value of stress peak up to 55% thus lowering the size of edge chipping [9].…”

“…An experimental investigation done on K9 glass shows that intermittent RUM can lead to reduction in the cutting force while comparing with continuous RUM and had a relationship close to linear [8]. An experiment performed on titanium alloy (Ti6Al4V) resulted that the cutting force can be reduced when we increase ultrasonic power at the given condition of low spindle speed and diameter of tool [27].…”

Ultrasonic machining (USM) is a process used for machining material with high hardness and brittle nature that are difficult to machine. The USM has an upper hand on the other non-conventional process like electron discharge and laser beam machining which have thermal effect on workpiece. Workpiece chracteristics are also not limited by chemical and electrical properties. This paper discusses about the rotary ultrasonic drilling (RUD) machining process which is a variant of USM and the recent developments that it gone under through the RUD. This paper also reviews about the various methodology adopted by researchers to achieve optimum output parameters like Material Removal Rate, Surface roughness, Edge chipping etc. by altering the process characteristics like spindle speed, feed rate, ultrasonic power etc. as well as machine characteristics like tool type, support length etc. The paper also deals with the material used with the RUD worldwide and the findings of researchers on them.

“…The experiments were performed by a recently developed novel surgical theater compatible machine prototype ( Figure 1). RUBD process differs from ultrasonic-assisted drilling in a way that RUBD process works on the principle of rotary ultrasonic machining (RUM), and uses a diamond abrasive-coated rotating tool with axial ultrasonic vibration for material removal, 29 whereas, in ultrasonic-assisted drilling, the ultrasonic vibrations are provided to the conventional rotating tool. The experiments were performed in two phases.…”

Cutting force and torque are important factors in the success of the bone drilling process. In the recent past, many attempts have been made to reduce the cutting force and torque in the bone drilling process. In this work, drilling on human cadaver bones has been performed using rotary ultrasonic bone drilling process to investigate the effect of drilling parameters on cutting force and torque. The experimental work was carried on a recently developed rotary ultrasonic bone drilling machine for surgical operations. The experimental work was performed in two phases. The first phase includes a comparative study between rotary ultrasonic bone drilling and conventional surgical bone drilling, to study the influence of various drilling parameters (rotational speed, drill diameter, and drilling tool feed rate) on the cutting force and torque. The results revealed that the cutting force and torque produced during drilling operations in rotary ultrasonic bone drilling were lesser (30%–40%) than conventional surgical bone drilling. In the second phase, response surface methodology was used to perform the statistical modeling of cutting force and torque in rotary ultrasonic bone drilling process. Analysis of variance was performed at a confidence interval of 95% to analyze the significant contribution ( p < 0.05) of process parameters (drilling speed, feed rate, drill diameter, and abrasive particle size) on the responses (cutting force and torque). The confirmatory experiments were performed to validate the developed statistical models. It was found that both cutting force and torque decrease with increase in drilling speed and increases with the increasing drill diameter, feed rate, and abrasive particle size.

“…In agreement with this, mechanical interlocking of the copper layer on the glass is because of the surface roughness. Therefore, mechanical roughening methods such as laser machining [128][129][130][131][132][133], ultrasonic machining (USM) [134][135][136][137][138][139][140], and electrochemical discharge machining (ECDM) [141][142][143][144][145][146][147][148][149] are used to enhance the adhesion by improving the glass surface roughness.…”

This article reviews the state-of-the-art electroless copper deposition on glass substrates and the associated challenges.The well-known issue of poor adhesion of electroless copper with the glass substrate was addressed and later, improved bymodifying the surface energy using a specific chemical treatment or by creating localized surface roughening. Localized surfaceregions in the glass were created by abrasive-based ultrasonic machining and hightemperature electrochemical-discharge machiningtechniques. The effect of critical process parameters on the surface roughness and morphology was explained. Both qualitative andquantitative adhesion measurement techniques, such as cross-hatch tests and 90°/180°p eel adhesion tests, were presented. Theadhesion strength is affected by the surface roughness of the substrate and residual stress build-up in the film. As the build-up stresscan be released by the post-deposition annealing, the adhesion strength is further increased. Finally, the electroless coppertechnology in making through-glass-vias and embedded redistribution lines are presented.
