Compared to conventional machining (CM), ultrasonic vibration-assisted machining (UVAM)
with high-frequency and small-amplitude has exhibited good cutting performances for …

Texturing of the surface is a technique to form the surfaces of the desired pattern. It is
extensively used to alter the mechanical and tribological properties, such as increased …

Microlens arrays of single-crystal silicon are required increasingly in advanced IR optics. In
this study, we attempted to machine spherical concave microlens arrays on a single-crystal …

The need for using alternative processes rather than electro-discharge machining (EDM) for
micro-parts has allowed micro-manufacturing (also known as precision engineering) to …

The machinability and tool wear behavior of 7050-T7451 aluminum alloy versus cutting
parameters and vibration frequency are compared between conventional cutting (CC) and …

This study presents a two-frequency elliptical vibration texturing (TFEVT) method that adds
elliptical vibration cutting (EVC) to a conventional texturing (CT) method. The TFEVT method …

The knowledge of cutting forces in various machining processes is of great importance not
only for the designer-manufacturer of machine tools, but also for the user, since the cutting …

Hardened steel has been widely used in the aviation and automotive fields owing to its
unique properties. However, the poor machining performance for finishing hardened steel …

Three-dimensional ultrasonic vibration-assisted turning with a dual-frequency drive can
improve the machinability of workpieces. The output path of the vibrating tool nose in this …

Although the direct texturing processes using dynamic cutting depth modulation have been
widely demonstrated for generating micro/nano-structured surfaces, the material shearing …
