Abstract

Precision machines are essential elements in fabricating high quality micro product or micro feature and directly affect the machining accuracy, repeatability and efficiency. Some design issues of precision machines are presented in this paper, and emphasis is placed on the mechanical and structural design of precision machine and relevant design methodology. In the discussion of mechanical and structural design of precision machine, particular emphasis is placed on the machining dynamics issue to identify the major structural factors affecting the performance of the machining. This paper begins with a brief review of the design principles of precision machine tools, including tool-workpiece loops and machine tool vibration, and stiffness, mass and damping issues with emphasis in the machining dynamics; Then design processes of precision machine are discussed; And finally two case studies about design of a fast tool servo system and a 5-axis micro milling machine tool are given.

Abstract

This paper describes a new technology platform for polymeric micro optical fluidic systems. The platform consists of active and passive optical and fluidic elements for a surface plasmon resonance (SPR) biosensor for the detection of proteins. The platform includes the integration of polymer light emitting diodes, polymer photodiodes as well as polymer based fluidic valves and pressure generation elements. Surface functionalization for micro optical and micro fluidic parts as well as advanced manufacturing methods are other important parts of the presented technology platform.
