Dual-Axial Tool Servo Diamond Turning of Hierarchical Micro-Nano-Structured Surfaces

نویسندگان

چکیده

This paper reports on a dual-axial tool servo diamond turning method for the one-step fabrication of hierarchical micro-nano-structured surfaces. With respect to motion (XZ), z-axis can generate primary surface with complex shape, and x-axis is used synchronously form secondary structure via controlling residual marks. The toolpath determination algorithm developed described in detail, effect machining parameters basic feature sizes generated structures investigated through conducting numerical simulation both generation. result indicates that additional x-axial effective deterministic generation variety structures. Finally, taking advantage an ultra-precision lathe self-developed tri-axial FTS, high accuracy practically generated.

Fabrication of Micro-Optical Devices Using Slow Tool Servo Diamond Turning Process

Micro-optical devices, e.g., micro lenses, micro mirrors, play an important role in high speed data, voice and video signal transmissions. In this study, a new method of fabricating micro optical devices was investigated. The method is different from traditional fabrication processes in the sense that that the micro optical elements were simultaneously machined in a process known as slow tool s...

Fabrication of Micro and Diffractive Optical Devices by Use of Slow Tool Servo Diamond Turning Process

In recent years it has become possible to fabricate freeform optics using multi-axes ultraprecision machines. Unlike conventional process where a single diamond tool is used to machine each individual lens one at a time, this research demonstrates the development of an innovative diamond tool trajectory which allows the entire microlens array or diffractive lens to be machined in a single opera...

Flexible Shape Extraction for Micro/nano Scale Structured Surfaces

Surface feature is the one of the most important factors affecting the functionality and reliability of micro scale patterned surfaces. For micro scale patterned surface characterisation, it’s important to extract the surface feature effectively and accurately. The active contours, known as “snakes”, have been successfully used to segment, match and track the objects of interest. The active con...
