As a new type of damage-tolerance titanium alloy, TC21 alloy is widely used in aerospace. However, TC21 is a difficult-to-machine material owing to its low thermal conductivity, high chemical activity and low elasticity modulus. In this work, minimum quantity lubrication (MQL) with graphene nanofluid was adopted in TC21 milling. In order to evaluate the effects of graphene nanoparticle on the surface integrity, a series of milling experiments were performed under the dry, gas, pure MQL and graphene nanofluid MQL condition respectively. Results showed that the graphene additive was effective for improving the surface integrity. Overall, the results could be explained that graphene additive could enhance the cooling and lubrication performances of the oil film formed in cutting zone. The findings of this work are expected to give a feasibility and some experimental basis for the application of the graphene additive in MQL milling.

An experimental investigation is reported on the surface grinding of intermetallic gamma titanium aluminide using electroplated cubic boron nitride grinding wheel. In order to implement the wide acceptability of this material in various fields, the machinability investigation finds crucial especially during grinding. In the present work, the machinability of gamma titanium aluminide of two different compositions was investigated by analysing the normal and tangential force, surface integrity, chip morphology and the condition of grinding wheel after the experiments. The minor variation in the composition of titanium aluminide has influence on the generated cutting forces, the knowledge of which is essential for satisfactory use of this material in various applications. The observations from the machined surface have shown the presence of various surface defects and the analysis of chip morphology revealed the occurrence of high temperature during the grinding. The topography of the grinding wheel is also investigated after the experiments.

The ultrasonic vibration assisted grinding is widely used in machining of hard and brittle material. This paper presents a study on the material removal mechanism in ultrasonic vibration assisted grinding of glass. The single diamond grain grinding experiments were performed with and without ultrasonic vibration assisted. The grinding force and acoustic emission signal were measured and analysed, and the ground groove morphology was observed and analysed in detail. The following conclusions can be obtained: 1) the material removal mechanism is changed from continuous crack propagation in conventional grinding to micro crack breakage in ultrasonic vibration assisted grinding; 2) the addition of ultrasonic vibration in grinding of brittle material can reduce the crack propagation distance; 3) compared with the conventional grinding, the energy distribution of acoustic emission signal in ultrasonic vibration assisted grinding is more concentrated.

The implantation of ceramic matrix composites (CMCs) is limited due to their high machining costs. To overcome this problem, modified grinding wheels, one macro-structured by segmenting and another laser-structured were used. The grinding tests were carried out at different material removal rates and cutting speeds. The grinding forces, surface roughness, and induced residual stress were compared. The results showed that the wheel structuring resulted in a better performance of the grinding wheel. The grinding forces were respectively 30% and 20% lower in the case of segmented wheel and laser-structured wheel in comparison with the conventional grinding. In addition, the tensile residual stress was reduced as a negative output of the grinding process via structuring. A high-speed high-efficient grinding of CMCs without presence of surface damage was achieved by optimising the process parameters. The material removal rate could be elevated without changing the grinding forces with application of the structured wheel.

With the rapid development of carbon fibre reinforced polymers (CFRPs) as main aerospace structural materials, it is necessary to manufacture CFRP structural components for high dimensional accuracy by means of precision machining. In this paper, orthogonal cutting was used to investigate machining process and surface quality of CFRP materials for precision machining. An intensive discussion was given about fibre orientation and cutting parameter range when machining CFRP for high accuracy application and optimised cutting method, including cutting speed, cutting depth, edge radius, fibre orientation, was obtained to reduce cutting force and surface roughness and get smooth surface topography. The cutting speed over 200 m/min and small cutting depth slightly large than edge radius were advisable, the fibre direction 0~45° and 90° were found suitable for precision machining. This paper provides theoretical and experimental supports for application of precision machining of CFRP materials.

This study focuses on one of the applications of nanofibre: abrasive buffing. We proposed the oil adsorption physical model of abrasive buffing and compared it with experimental results to develop a nanofibre buffing pad. For realising the free-form nano surface, such as moulding die surface, we conducted a base experiment with different diameter fibres and different size grains and investigated its base polishing characteristics compared with commercial felt buff. From the experimental results, we considered the buffing mechanism of fibre and grain contact the workpiece surface to polish. As a result, the effect of combination of mesh size and grain size on polished surface roughness of the workpiece was demonstrated, and controlling the polished surface roughness using this low-cost new abrasive material in abrasive machining was realised.

The five factors (abrasive grain, grain size, grade, structure and bonding material) of the three main elements (abrasive grain, bonding material and pore) of a grinding wheel are important parameters affecting surface quality and grinding efficiency, however it is difficult to determine an optimal combination of grinding conditions for workpiece material. In previous research, we constructed a support system for effectively selecting an appropriate grinding wheel using decision tree technique. We also proposed a visualisation process to show how grinding wheel elements and factors correspond to the materials characteristics of the workpiece material. In this research, to evaluate the usefulness of prepared visualisation maps and their effectiveness in deciding grinding wheel elements, we performed comparison experiments applying the surface grinding technique to JIS SUS310S material using PA abrasive grain as recommended by the grain-type visualisation map and WA and GC abrasive grains for comparison purposes. We found that visualisation maps enable quick selection of a grinding wheel even for the grinding of difficult-to-cut materials for which grinding wheel selection is usually difficult.

Based on the chip geometry, a new mathematical model is established to correlate specific grinding energy with the maximum undeformed chip thickness, the cutting length, and grinding parameters. This work investigates the energy of cemented carbide (YG8) grinding with a vitrified diamond wheel in high speed regime (the grinding speed of up to 120 m/s). The results indicate that the specific grinding energy increases with the rise of the cutting length, while decreases with the increase in the maximum undeformed chip thickness. The distribution mechanism of the grinding energy shows that the grinding energy is mainly expended for sliding and ductile plowing. A nearly proportional relationship is obtained between the consumed power per unit width and the plowed surface areas generated by all cutting points per unit width. Compared to conventional grinding, it is found that specific grinding energy requirement is increased for high speed grinding of cemented carbide.

The machine tool is the main execution unit in the cyber-physical system (CPS system), which can improve the product quality by dynamic monitoring and real-time perception of its wear status. In order to realise the online signal acquisition and monitoring of tool wear status, the spindle power signal acquisition system was implemented. The cutting force signal is used as contrast analysis. The HHT method and wavelet transform method are introduced to construct the tool wear coefficients, which are corresponding to the tool wear status. Compared with the wavelet transform, it is proved that Hilbert-Huang transform can restrain the noise signal effectively and improve the accuracy of the monitoring. Finally, the new tool wear monitoring method is applied to drilling 45# steel and titanium alloy TC4 to catch the tool wear state, and the power signal is used to carry out comprehensive online tool state monitoring. It is accurate and practical in the drilling test, which shows prospective usage in the near future.

Zirconia ceramics have wide applications in the fields of aerospace, defence industry, new energy, automotive, electronics and biomedical. However, scratches, micro-cracks and sub-damage are inevitable by using conventional methods. The magnetic-assisted polishing with MCF slurry is considered as a friendly polishing method which can not only achieve smooth surface but also reduce the defects. However, the investigations on the high precision polishing of zirconia ceramics by using the MCF slurry were not conducted so far. In this work, the polishing method by using magnetic compound fluid (MCF) slurry under the rotary magnetic field was proposed for the zirconia ceramics polishing. The principle and the constructed experimental setup were presented at first. Then, the spot polishing was conducted. Finally, the effect of parameters on the finishing of work surface was investigated. Experimental results showed that zirconia ceramics workpiece could be smoothed effectively with the optimised polishing conditions.
