Fringe deflectometry technique (FDT) plays a more and more important role in specular surface measurement due to its large slope measurement range. However, its accuracy is heavily dependent on the quality of the extracted phase. The gamma effect of liquid crystal display (LCD) and CCD introduces significant phase distortion, resulting in a periodical phase error and measurement error. A mathematical model is established to illustrate phase error introduced by gamma effect, and an optimal algorithm based on four-time four-step phase-shifting (FFPS) is proposed to retrieve phase. Simulation results prove that FFPS phase retrieval method can compensate for the phase error caused by the nonlinearity of the LCD and CCD point-by-point, thus it is immune not only to calibration error, but also to the non-unitary of the gamma effect spatially and temporally. Experimental results are also presented to verify the performance of the proposed method.

A large amount of material is removed during the milling of a water chamber head manufactured of high-strength 508III steel. The performance and service life of coated cemented carbide inserts have significant influences on processing efficiency and the quality of nuclear power components. This study will conduct single-factor milling experiments of water chamber heads relevant to practical working conditions. Influences of different milling parameters on the insert failure behaviour are analysed based on experimental results and simulation data. The failure mechanism of insert wear and fracture was also discussed. Finally, the influences of coating types and thickness values on the wear behaviour of cemented carbide insert while cutting 508III steel were investigated. The results of this research can be implemented in the improvement of coated cemented carbide inserts in regards to failure resistance and service life.

The bath compositions are critical to mechanical performance of the coating layer for electroplated diamond tools. In this paper, the effects of different chemical components in bath solution on mechanical properties including tensile strength and hardness of the electroplated coating were investigated by orthogonal experiments. The influences of different chemical components including nickel sulphate, cobalt sulphate and sodium chloride on mechanical properties of the electroplated coating were analysed. The results showed that increasing the component of nickel sulphate caused an unstable situation on tensile strength and hardness of the electroplated coating. However, hardness of the electroplated coating could be improved by increasing the component of cobalt sulphate. The concentration of sodium chloride had no obvious effect on mechanical properties of the electroplated coating layer. The experimental results revealed that the optimised bath compositions were at 270 g/L nickel sulphate, 20 g/L cobalt sulphate, and 10 g/L sodium chloride.

ZrO2 ceramic materials have outstanding propertied, like high wear resistance, good corrosion resistance, low thermal conductivity, etc., and has been widely applied in modern industry. However, ZrO2 ceramic is one of the difficult-to-machine materials, which would lead to rapid tool wear and poor surface quality. Micro turning combined with pulse laser, as a new kind of process in machining ZrO2 ceramic, is studied in this paper. And a comparative research between micro turning with and without pulse laser assisted of ZrO2 ceramic has been conducted. The results revealed that under the same machining parameters, both the cutting force and machined surface roughness obtained in pulse laser assisted micro turning was smaller than that in micro turning without pulse laser, and the pulse laser could effectively reduce the tool wear. The work carried out in this paper would be helpful to the further research on the pulse laser assisted micro machining of ZrO2 ceramic.

The increasing demand for energy, coupled with concerns over pollution and climate change, has led governments to establish policy frameworks to reduce CO2 emissions. Moreover, rises in energy price and increasingly greener customer behaviour are pushing the manufacturing industries to develop more sustainable processes. As a major source of energy consumption in manufacturing systems, machine tools have been the focus of sustainability research communities worldwide. This paper provides a survey of manufacturing industry's sustainability trends and presents a technology-foresight-based methodology for gathering key information on the research development in this topic. Furthermore, a correlation between real world aspects, such as legal, economic and environmental, and the development of research on energy consumption and efficiency of machine tools is provided. The results highlight the leading countries, institutions, authors and subject areas in this field. Research and development shows a high correlation with governmental actions, and appears to be of core importance to meet CO2 reduction targets.

Axicon lenses, characterised by their cone shape, have rotational symmetry. The generatrix of axicons is the surface profile going across the apex of the axicon and the cone angle of the axicon can be calculated from the generatrix. Axicons, widely used in optical alignment and Bessel-Gauss beam generation, require high accuracy in surface and cone angle metrology. However, current methods focus on measuring the cone angle with a stylus profiler, a process in which misalignment and displacement are common when measuring the generatrix. A method is proposed that multiple parallel measurement paths near the apex of the axicon will obtain the generatrix with the specific algorithm. In experiments, the axicon with a cone angle of about 90° was measured by the stylus profiler method (Taylor-Hobson PGI 3D) in the 0.5 mm, 0.4 mm and 0.3 mm distances, whose results show good agreement in the cone angle range and generatrix error. Experimental results prove the feasibility of the proposed method.

AISI 52100 steel has been widely used in various types of bearings in machinery equipment due to its excellent mechanical properties and high availability. In the final manufacturing process of bearing parts usually involve lapping and polishing methods on the ultra-precision machining in order to achieve high accuracy of profile and fine surface quality. The essence of this process is abrasive wear of AISI 52100 steel material. Therefore, in order to improve the super finishing process of bearings super finishing, the experiment of abrasive wear of AISI 52100 steel materials were carried out in this paper. The effects of different abrasive diameter and pressure on the material removal amount of AISI 52100 steel were investigated; the abrasive correction coefficient K in Preston formula was computed and obtained. The result shows that reducing the abrasive diameter can increase the material removal rate and improve surface quality when other factors are maintained constant.

In recent years, micro-milling techniques have attracted great attention and interest from academia and industry. Inconel 718 is a nickel-based superalloy with good tensile, fatigue, creep and rupture strength and can find great application in nuclear and aerospace industry. In this paper, the response surface methodology (RSM) was applied to develop the model for predicting surface roughness in micro-milling Inconel 718. The magnitudes of cutting parameters affecting the surface roughness, which were depth of cut, spindle speed, and feed rate, were analysed by the analysis of variance (ANOVA). The validity of the surface roughness prediction model was proved due to the tiny error between the measured values and the prediction results. Then, genetic algorithm (GA) was used to determine the optimal cutting parameters achieving minimum surface roughness in micro-milling Inconel 718 process. All experiments show that the optimised results agree well with the test ones.

The tunable range and beam linewidth of distributed feedback laser were determined by fabrication quality of the periodic linear micro-groove array on substrate, which grooves are high sloped and ranged sub-micron to few microns. Compared with the common micro-groove arrays (size from tens of microns to sub-millimetre), the ultra-precision cutting of these tiny and high-sloped linear micro-groove arrays are more difficult to realise. In this paper, a series of investigations was proposed for ultra-precision cutting of linear micro-groove array on polymethyl methacrylate (PMMA). Firstly, the different cutting processes included planing and fly-cutting were conducted. The workpiece morphology, surface quality and machining efficiency of these processes were investigated. Then, the fly cutting process was optimised by the calculation of non-free chip zone and the analysis of chip interference by cutting experiments. Finally, a novel tool positioning method based on acoustic emission was presented in order to realise high accuracy control of micro-groove arrays dimensions.

KDP crystal is a kind of excellent electro-optic material used in many laser facilities, which is also widely acknowledged to be extremely hard to machine. In this work, we developed a process to finish KDP crystal to a precision and clean engineering specimen. A micro-nano water dissolution principle and its planarisation mechanism in the machining process are illustrated, which turns the disadvantaged deliquescence property of KDP crystal into the driving force for ultra-precision polishing of the crystal. Micro emulsion fluid with nano water nuclei can precisely control the material removal and realize the selective polishing, thus forming a super smooth and precise surface. Then a subsequent cleaning process developed specially for this ultra-precision polishing method helps to get rid of the polishing fluid, and finally reduces the residue off the crystal to a clean and tidy surface with 1.964 nm rms roughness for engineering application.
