Hundreds of optic units are used in large high-power laser facility. The misalignment problem of those optic units has a very negative impact on performance of carrying high-power laser. In this paper, using the example of reflecting mirror, we have carried out a fundamental analysis on the misalignment of optical unit in assembly, transfer and deployment. It is found out that there is an obviously existing conflict to meet the both requirements of stable fixturing and precise alignment, if considering the mirror's stiffness. Some improvement suggestions are given finally, and further work is undertaking to develop an optimized assembly design of optical unit.

The kinematic joints of machine tool feed system are crucial for the dynamics modeling. It affects the dynamic characteristics of machine tool feed system, and then there will be a significant influence on machining quality of workpieces. Considering the gravity of spindle box components, a dynamic model of vertical axis feed system was established using lumped parameter method in this paper. The axial stiffness of the screw-nut and up/down bearings was calculated based on the dynamics model. The transmission stiffness of the feed system was obtained when the nut moved to the middle of the screw. Furthermore, the feed system's natural frequency and acceleration vibration response in transmission direction were analyzed. Taking the vertical axis ball screw spindle box feed system of a three-axis high-speed vertical machining center as an example for analysis, the results show that the stiffness of the screw-nut, the stiifness of the up bearing and the down bearing, the transmission stiffness of the feed system varied about 34. 8%, 10.0%, -12.5%, 12.5% respectively compared with the situation ignoring gravity effect. The natural frequency and the amplitude of acceleration vibration response varied about 6.3% and 7.0% respectively. The theoretical data of natural frequency varies about 4.7% compared with the experimental data while that of the amplitude of acceleration vibration response is about 18.0% lower than the experimental data. When the gravity effect is ignored, the analytic value of natural frequency changes about 10.4% compared with the experiemental value, while the analytic amplitude of acceleration vibration response drops about 23.4% than the experimental one. Thus, the dynamic model of vertical axis feed system considering the gravity effect presents higher analytical accuracy.

In this paper Au ring microelectrodes are fabricated and characterized. With an optical fibre core as a substrate Au film with thickness 300nm was coated by an electron beam evaporation system, then on this Au coated substrate a parylene passivation layer was deposited, forming the desired Au ring microelectrode. Scanning electron microscopy (SEM) was used to characterize the quality of the deposited films and the adhesion at the interfaces. With a CHI660D electrochemical workstation the electrochemical characterizations were performed at room temperature in a conventional three-electrode system. Cyclic voltammograms as a function of scan rate were sigmoidal form, a typical electrochemical response of microelectrodes. AC impedance frequency spectrum of the fabricated Au ring microelectrode was also obtained in a reversible system, and good agreement was found with the Randels-type equivalent circuit.

The act of surface refurbishment of worn components is of itself both environmentally friendly and something which can be accomplished in a timely and convenient manner. It is environmentally friendly since it conserves both material and energy which would be otherwise expended in producing new components. It thus follows that it is also a convenient time-saver. There are many approaches to surface refurbishment, which include Laser Engineered Net Shaping (LENS), and weld repair, to name just two. All are likely to involve machining in the generation of the new surface. It is true to say that, indeed, most metallic surfaces will have experienced some degree of machining. This leads to the possibility that the properties of surfaces generated by machining are likely to be affected by their superficial state of stress and characteristics of the refurbished layer. Therefore our proposed research is in the characterization of the machinability of the remanufactured surface and the subsequent component performance. Such characteristics include fatigue, corrosion and oxidation.

In order to diagnose the location and size of fault in rolling element bearing system accurately, two-DOF dynamic model and six-DOF dynamic model of fault bearings are built and compared with each other based on the generation mechanism of bearing fault. The models not only consider the influencing factors of variable stiffness caused by bearing clearance, but also introduce a unit resonator to simulate high frequency inherent vibration arising with the bearing fault in sixDOF dynamic model. Dynamic models of localised fault on outer race, inner race and rolling element of rolling element bearing are simulated and analyzed by using Runge-Kutta method. The simulating results are in accordance with experimental results, which proves the accuracy and practicality of the models used in engineering application.

With the rapid printing speed and low cost, Three Dimensional Printing (3DP) is widely used. However, the dimensional accuracy of components are not perfect due to the shrinkage and deformation of component after the printing and post-processing. This study analyzes the factors affect the printing accuracy in 3DP and determines the range of shrinkage of the printing process. Neural Network (NN) is used to describe the complicated relationship between the dimensional accuracy of component and printing parameters. In order to minimizing dimensional error of specimen, Genetic Algorithm (GA) is used to optimize the 3DP print parameters such as binder saturation, the layer thickness and shrinkage compensation in X, Y and Z directions respectively. The four experiments with default parameters, the limits in the range of print parameters, and parameters from NN-GA are conducted, and the results show that the dimensional error is much lower using the printing parameters from NN-GA, and also show that the NN-GA is capable to promote the dimensional accuracy of 3DP and provide the reference for other forms AM technology.

Traditionally, analyzing the load-bearing characteristics of complex structural components pays more attention to static factors ignoring dynamic factors. Static elements focus on the distribution of stress while dynamic element on the flowing tendency of various loads in different directions. Load path is a new expression of dynamic element and this paper take the engine's cylinder head as study object to analyze the load-bearing characteristics of complex structural components using load path theory. In order to simplify the problem, slices of the first cylinder are researched and conclusions are drawn to prove the effectiveness of load path theory.

3D vision-based recognition as well as grasping of complex objects is required not only for detection and categorization but also for pose estimation and robotic pick-and-place operations. In this paper, we propose a structured light camera based 3D visual perception and tracking system application with robot arm grasping for manufacturing. In the first step, we use a geometric surface primitive patch segmentation approach based on Hough transforms to obtain accurate surface normal estimations from 3D point clouds for the identification of patch primitives. The most relevant primitives for our application include planar and cylindrical surface patches. We extract primitive surface patches from automotive CAD models in DXF or 3DS format. The models are then decomposed to simple entities such as planar polygons, vertexes and lines. Our system takes advantage of the available CAD data for both object recognition and for pose estimation. In the final step, we propose point based KLT tracking method with dominant features from object recognition results both raw data and CAD. Our experimental results demonstrate that we can show application results from YASKAWA MOTOMAN robots demonstration. Whole processes perform within few seconds, an accurate pose and reasonable tracking.

Nonlinear stiffness of rolling bearing is the root cause of the nonlinearity of a bearing rotor system. In this paper, bearing stiffness is calculated with a complete model for angular contact ball bearing. The bearing stiffness matrix is then integrated with finite element model of a rotor to study the nonlinear stiffness of rolling bearings. Calculated results are compared with the results of FAG's online tool (BearinX®) and experiments as well. The good agreements show the accuracy of the presented model. Based on the model of a two-bearing rotor system, the variations of bearing stiffness are studied from three aspects, i.e., external axial forces effects, external radial forces effects, and high speed effects, which may provide theoretical proofs for the study of bearing rotor systems.

In order to ensure full utilization of modern multi-functional manufacturing technologies, it is important that up-to-date information of the resource capabilities is always available for the design and planning activities. This paper presents an ontological approach for representing resources and their capabilities, and a framework in which the resource capabilities are matched with product requirements. The paper integrates two separate works of different universities, TUT and LUT. In order to show a practical example of the usage of the capability model and capability matching developed by TUT, the approach is applied to a case study from sheet metal manufacturing. The extensive research of LUT on the interconnectedness of turret punch press machines and tools with product properties is used as an input for the formulation of the capability description of turret punch press and for formulating the rules for the detailed capability matching.
