Precision Measurement of Cylinder Surface Profile on an Ultra-Precision Machine Tool

Profile Generation for Brittle Materials by Using Ultra-precision Lathe with On-machine Measurement System

Dynamic Accuracy Design Method of Ultra-precision Machine Tool

Ultra‐precision machine tool is the most important physical tool to machining the workpiece with the frequency domain error requirement, in the design process of which the dynamic accuracy design (DAD) is indispensable and the related research is rarely available. In light of above reasons, a DAD method of ultra‐precision machine tool is proposed in this paper, which is based on the frequency d...

Precision surface measurement.

Surface size, geometry and texture are some of the most influential subjects in the fields of precision and ultra-precision engineering, defining the functional interface through which emerging products operate. Next-generation products demand super-smooth surfaces, freeform geometries or even deterministically introduced microstructures to provide functional performance. Technological progress...

An integrated system for ultra precision machine tool design in conceptual and fundamental design stage

This paper presents an integrated system used for ultra precision machine tool (UPMT) design in conceptual and fundamental design stage. This system is based on the dynamics, thermodynamics and error budget theory. The candidate configurations of the machine tool are first selected from the configuration library or a novel configuration designed by the user, according to the functions of the ma...

Atomic Step Formation on Sapphire Surface in Ultra-precision Manufacturing

Surfaces with controlled atomic step structures as substrates are highly relevant to desirable performances of materials grown on them, such as light emitting diode (LED) epitaxial layers, nanotubes and nanoribbons. However, very limited attention has been paid to the step formation in manufacturing process. In the present work, investigations have been conducted into this step formation mechan...
