The effect of different welding parameters on joint strength and fracture surfaces was investigated, and the optimal welding parameters were determined using the Taguchi method. Results revealed that low heat generation led to weak mechanical interlocking between GFRP and the thermoplastic interlayer, while high heat generation caused degradation of the aluminum/thermoplastic polymer interface. The tool traverse speed was found to be the most influential parameter in terms of joint strength, followed by plunge depth and rotational speed. Moreover, thermal measurements were conducted during the welding process using thermocouples. An uneven thermal distribution was discovered across the overlap area due to dissimilar substrates. This issue was resolved by incorporating aluminum thermal insulation, resulting in improved heat distribution and a significant enhancement of 94% in joint strength. Scanning electron microscopy (SEM) was employed to identify joining mechanisms and examine the effect of welding parameters on joint microstructure. Furthermore, Fourier-transform infrared spectroscopy (FTIR) was used to investigate chemical bond formation at the aluminum/thermoplastic polymer interface.

Firstly, two cutting mechanisms (shear-slip and plough-slip) are distinguished according to the relative tool sharpness (RTS) which is determined by the cutting tool radius and cutting depth, and the fine characterization model for drilling stress of the workpiece is constructed by considering the two cutting mechanisms. Then, in order to overcome the problem that model parameters are difficult to be accurately determined, the sub-interval decomposition optimization method (SDOM) and the improved particle swarm optimization (PSO) are employed to identify parameters in the model.

Moreover, grinding is widely used as a finishing process in workpieces since it provides excellent surface roughness and dimensional tolerances. Due to the high volume of cutting fluid used in conventional lubrication (flood), associated with harmful effects such as contamination and intoxication, alternative methods have become highly necessary. The minimum quantity lubrication (MQL) technique reduces fluid use but has low cooling capacity, in addition to barely removing chips, making it essential to seek improvements to make it competitive. In this sense, adding water to the MQL can improve the cooling capacity at the cost of reducing lubrication. At the same time, applying a wheel cleaning jet (WCJ) of compressed air assists in chip removal. Thus, this work aims to analyze the results of external cylindrical grinding of alumina (Al<sub>2</sub>O<sub>3</sub>) using a synthetic diamond grinding wheel, comparing the techniques of conventional MQL, diluted MQL, and MQL + WCJ against the flood method. Surface roughness, roundness deviation, diametrical wheel wear, G ratio, grinding power, tangential cutting force, grinding cost analyses, and CO<sub>2</sub> pollution emission were conducted for this. The results show that adding water to MQL, associated with WCJ, significantly improved roughness, wear, and grinding power.

This research work investigates the microstructure and mechanical properties of PH 13–8 Mo martensitic stainless-steel parts produced via LMD. The workshop trials were conducted using an LMD system collaborated with a robotic arm to deposit single-track thin walls and horizontal blocks. The microstructural characteristics of the additively manufactured parts were analyzed using an optical microscope. The mechanical properties were evaluated through hardness measurements and uniaxial tensile tests. The influence of energy density and powder deposition density on the characteristic geometry of straight walls was also investigated. The microstructural analysis showed that the microstructure consisted of columnar dendrites that grew epitaxially from the substrate, with primary austenite cells containing intercellular ferrite and martensite laths that were roughly parallel with the retained austenite. When the energy density increased from 43 to 86 J/mm<sup>2</sup> (a doubling of energy density), there was an increase in secondary dendritic arm spacing (SDAS) by approximately 250% in the first layer and approximately 90% in the top layer. The difference in SDAS change between the first and top layers can be attributed to the difference in cooling rates experienced by each layer during the additive manufacturing process. Increasing powder deposition density from 0.5 to 1 g/min results in a decrease in porosity from 3% to less than 1% and an increase in strength from 800 to over 1000 MPa. The hardness of the deposits was found to range from 300 to 400 HV.

Porosity, microstructure, residual stresses, and fatigue life of Inconel 718 samples manufactured by laser powder bed fusion (LPBF) and then treated by LSP have been evaluated.

The LSP setup was the waterjet arrangement without protective coating. Residual stress distribution as a function of depth was determined by the hole-drilling method. Fatigue specimens were LSP treated on both sides and then cyclic loading was applied with <i>R</i> = 0.1. Residual stress profiles of as-built specimens showed tensile residual stresses while specimens with LSP exhibited compressive residual stresses. Fatigue life in specimens with stress relief heat treatment plus LSP showed an increase of 18–22% with respect to that of as-built specimens. Porosity levels were lower than 1% in the tested specimens, while surface microhardness increased due to LSP.
