“…Compared with macro assembly, the critical challenges in the micro-assembly include the required positional precision and accuracy, the mechanics of interactions due to scaling effects, and the highly precise hand-eye coordination of the operator [3]. In conventional microscope, there is a bottle neck that limits the observation and depositing of objects with higher precision.…”

Abstract. The ability to manufacture and manipulate components at the microscale is critical to the development of micro systems. This paper presents the technique to manipulate micro/nano parts at the micro/nano-scale using an integrated Focused Ion Beam (FIB) system composed of scanning electron microscope, micro manipulator and gas injection system. Currently the smallest gears manufactured with traditional techniques were reported to have a module of 10 μm. As a test example, in this research we applied the above integrated FIB technique and had successfully fabricated micro gears with module of 0.3μm, with the precision improved for more than thirty times compared to the traditionally manufactured gears. Currently the integrated FIB technique is extended to cover the micro-assembly of devices in our centre, besides the micromanufacture procedure.

“…(2) The impact on the stability of the coordination. For clearance fit, due to the unevenness on the micro surface of the workpiece, the fit gap gradually increases during the working process, which affects the fit properties; For interference fit, the micro peaks and valleys may be smoothed out during the assembly process, resulting in a low actual effective interference and reducing the connection strength of the workpiece [4][5][6][7][8] (3) The impact on fatigue strength. For most mechanical parts, they are mostly in a state of metal fatigue, which refers to the phenomenon of material rupture under alternating stress.…”

Conduit connectors are widely used in the manufacturing of aviation equipment such as aircraft engines and aircraft assemblies. The surface roughness of conduit connector is a key quality characteristic to ensure the sealing connection of pipeline systems. Small deviations in the surface quality of conduits can lead to significant quality issues in aircraft, so high-precision measurement of micro roughness of conduit connector surfaces is of great significance for controlling aircraft quality and optimizing support manufacturing processes. Compared with contact measurement methods, optical measurement methods take an irreplaceable position in micro-nano scale roughness measurement which have many advantages such as non-destructive, high-precision and high-speed. An optical measurement method for surface roughness of aircraft conduit connector based on a triangular structured illumination system is proposed in this article, which combines high-precision fringe phase analysis algorithm and accurate height mapping algorithm to realize morphological restoration and the calculation of the roughness of the tested area. Relational experiment is carried out to verify the feasibility of the proposed method.

The thesis presents research carried out in the field of design for microassembly (DFIlA), a field that has hereto been characterised by the absence of well defined methodologies intended to facilitate transfer of prototypes from the research lab to production on industrial scale. A DFIlA methodology has been developed, serving the purpose of integrating product and micro assembly process development. It aims in particular at increasing the efficiency of the microproduct development process, decreasing the development time and the product and process cost, and enhancing the product quality.Chapter 1 presents the motivations, objectives, and structure of the thesis. The work carried out is inspired by the need to overcome barriers currently existing between the making of single research products and production on an industrial level. The main objective is to contribute to the creating of a novel DFIlA that supports product design and process selection, thereby facilitating the efficient assembly of complex three-dimensional miniaturised devices. This is complemented by a range of secondary targets that deal with the development and verification of supporting methods and models related to DFIlA.The summary of a comprehensive literature review is given in chapter 2. The survey provides results of studies closely related to the work reported in this thesis and relates that work to a larger ongoing dialogue about the topic of assembly and design in the microworld.
