Laser assisted machining is an alternative to conventional machining of hard and/or difficult-to-process materials which involves pre-heating of a focused area with a laser beam over the surface of the workpiece to cause localized thermal softening along the path of the cutting action. The main advantage that laser assisted machining has over conventional machining is the increased material rem...

Micro components are available in a variety of shapes typically sizing from 1 mm down to 0.01 mm. Their mass production is quite common using state of the art production technology. Micro spheres for example, are on the one hand available in lot sizes up to some thousands in a constant quality within micron accuracy [1]. On the other hand they are quite commonly provided as bulk material with d...

In the fabrication process of thin-walled micro-parts, both micro-cutting tools and micro-parts have characteristics small size low stiffness. Therefore, regenerative chatter during machining cannot be ignored. The influence tool runout error actual trochoidal trajectories cutting edge on micro-milling forces should also considered comprehensively. this paper, in is first analysed, an instantan...

Cutting force measurement is a quintessential task for status monitoring during machining. In the past, a number of cutting force sensors have been developed, each featuring a different set of performance advantages. In a pursuit to improve the measuring sensitivity and reduce the cross-interference error, in this paper we propose a triaxial cutting force sensor based on a commercial micro-elec...

Tool runout, cutting edge radius-size effect, and tool wear have significant impacts on the force of micro-milling. In order to predict micro-milling related performance, it is necessary establish a model including radius, wear. this study, an instantaneous uncut chip thickness (IUCT) considering nonlinear shear/ploughing coefficient cutting-edge friction embedded with flank width are respectiv...

Cutting processes are unstable machining processes. The influence of the instability on the deformation mechanism that leads to the chip formation at the atomic scale is analysed in this paper. Fundamental aspects of the crystalline networks deformation are underlined by using molecular dynamics technique applied to the microscopic level of the deformed material and are defined as basic instabi...

INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting ...

Recently, bubble-propelled micro/nanomotors have been considered as the cutting-edge micro/nano-sensing tools that use their unique features for fast detection of various hazardous environmental pollutants and biosensing.
