The presence of initial residual stress is a major contributor to machining distortion. To control machining distortion, the transition structure before the finishing stage is optimized in this paper. The first step is to create a machining distortion analysis model for long beam parts based on initial residual stress. The transition structure's topology optimization model is then established. Finally, a verification case is used. The proposed model is verified by simulation and experiments.

In order to enhance the accuracy of predicting grinding forces during the surface grinding of knife-like tool blades, a novel analytical-regression correction method has been introduced. This method analyzes the changing contact line between the grinding wheel and the tool and refines the variable edge-width grinding force model through the use of exponential coefficients in a regression analysis. This significantly improves the predictive accuracy of the model.

A contour error prediction model based on LSTM (long short-term memory) is established. By inputting power, vibration signal, and temperature values, the contour error of parts can be predicted to adjust the feed speed in real time.

The model is compared with other models, and the optimal model is selected to obtain the optimal prediction effect.

According to the structural characteristics of the blisk, a new adaptive belt tool system for the blisk finishing is developed. Due to the strong nonlinearity of the pneumatic system, a two-dimensional fuzzy PID controller is developed for the pneumatic force control. Finally, the experiments show that the polishing process is very stable and the roughness after polishing is less than 0.4 μm, which proves the effectiveness of the proposed new belt tool system and the fuzzy PID controller.

In order to improve modification effectiveness, a novel UV-assisted chemical modification (UVA-CM) strategy is proposed based on UV photocatalytic theory, which contributes to developing a novel hybrid chemo-mechanical process monocrystalline silicon. A series of comparative experiments was performed to evaluate modification effectiveness among different strategies. The results show that the liquid–solid chemical modification effect is obviously enhanced through UV advanced oxidation reactions.

Liquid-metal direct writing is a cost-effective and green technology, which is very promising for the customized fabrication of flexible circuits and functional devices. The smooth flowing and conveying of liquid-metal ink are still huge challenges that need significant attention. In this paper, the force mechanism of liquid-metal ink transported by ball rotation and translation of the printing head was analyzed. The flexible complex circuit and functional electronic pattern were printed.

In this paper, a lined pipe was formed through a drawing process. In double-layered pipes, shear strength is the most important design factor. We verified the effect on shear strength by changing the pipe surface roughness. In order to apply the surface roughness in FEM analysis, the surface roughness was converted to the friction coefficient. Through FEM analysis, we obtained a critical value for the change in shear strength.

Non-circular grinding is used in the grinding of crankshafts. In this study, an equation for detecting the angle error in non-circular grinding is established. Previous studies did not exclusively detect the errors caused by bending deformation and torsional deformation. However, the established equation detects these errors separately. The angle error was found to be up to 0.44 arcsec, which is 5 % of the angle error obtained from previous studies.

The paper proposed a normal contact stiffness model considering 3D topography and elastic–plastic contact of rough surfaces. The proposed model is validated using experimental tests conducted on two types of specimens and is compared with published theoretical models. The proposed model can provide a tool for efficient calculation of the contact force, deformation, and contact stiffness in engineering surfaces.

The paper highlights the importance of process parameters in the electromagnetic sheet metal forming process. Aluminium alloy I(Al6061T6) sheets with varying thicknesses were deformed by varying current, voltage and number of turns of the coil. A numerical model was also developed to predict the behaviour of the sheet under different processing conditions. The simulation and experimental results were in good agreement.

This research investigates the outcome of wire EDM process over the taper cross-sectional workpieces of Titanium Alloy (Ti6Al-4V). The outcomes result in better kerf width, surface finish, wire wear and metal removal rates, which can be controlled by taper angle of the workpiece, current, and pulse-off time. The effect of these parameters over the four outcomes of the wire EDM process have been studied in this research. Mathematical models have been developed to predict the outcomes.

Rotary forging is a continuous local pressure plastic forming technology. The equipment to realize the rotary forging technology is called the rotary forging machine. In this paper, the finite element analysis of the frame of the rotary forging machine is carried out, and then the structure and size of the machine frame are optimized. Finally, the experimental results show that the grain size and hardness of the formed workpiece are improved, which shows that the optimization scheme is reasonable.

The paper provides a comparative study of dry, wet and cryogenic turning of Ti-6Al-4V. Usually, it is recommended that titanium should be machined under lubrication, however, conventional lubricants are considered carcinogenic and health hazards. In this regard, cryogenic cooling using liquid Nitrogen provides an environment friendly option to machine Titanium based alloys.
