The study summarized the characteristics of large board and shaft components. The high-end large machine equipment and clamping devices should be developed in machining for high requirements. Additionally, some non-conventional methods have became a increasing for large components. For measurements, the developing and advanced methods were summarized, and the compensation methods were also complement to realize the high precision and efficiency. If that the component’s size has greatly exceeded the range of the current equipment, the mobile equipment are recommended for machining and measurement, and its detection technology is developed essentially for multiple mobile ones. Thus the study has guiding significance for achieving the high-precision and efficiency machining and measurement for large components, which is a great need in related industries.

“…Residual stresses can be determined through experimental measurement or simulation processes. Experimentally, residual stresses can be determined via destructive, semidestructive or non-destructive methods [12]. All destructive and semi-destructive residual stress measurement methods, such as hole drilling, digital image correlation, and contour methods, work on the same premise of stress relaxation followed by strain or deflection measurements [13].…”

The study reviews the numerical methods for predicting residual stresses in parts manufactured with additive manufacturing (AM) technique, such as laser powder bed fusion (L-PBF). L-PBF is a fast-growing technology with enormous potential for creating complex geometries with improved properties as compared to conventional processes. However, parts produced with L-PBF are susceptible to higher magnitudes of residual stresses, particularly tensile stresses as compared to compressive stresses, leading to geometrical distortions. While newly developed materials offer excellent properties and benefits to the industrial sector, the residual stresses that develop when parts are produced using the L-PBF process remain unexplored. The study evaluates three numerical simulation methods, such as thermomechanical modelling (TMM), inherent strain method (ISM), and multi-scale modelling (MSM) used to predict residual stresses in L-PBF parts. Each method has its advantages and limitations, and the best method depends on the specific application and available resources. The review highlights the potential benefits of numerical simulation methods for predicting residual stresses in L-PBF parts and compared to experimental results. Thus, the study recommends that future research should focus on improving the accuracy of numerical simulation methods for predicting residual stresses in L-PBF parts through refinement processes and exploring the impact of residual stresses on the L-PBF parts through detailed characterization.

Nowadays, one of the most crucial focus in the aluminium-foundry sector is the production of high-quality castings. Mainly, High-Pressure Die Casting (HPDC) is broadly adopted, since by this process is possible to realize aluminium castings with thin walls and high specific mechanical properties. On the other hand, this casting process may cause tensile states into the castings, namely residual stresses. Residual stresses may strongly affect the life of the product causing premature failure of the casting. Various methods can assess these tensile states, but the non-destructive X-Ray method is the most commonly adopted. Namely, in this work, the residual stress analysis has been performed through Sinto-Pulstec μ-X360s. Detailed measurements have been done on powertrain components realized in aluminium alloy EN AC 46000 through HPDC processes to understand and prevent dangerous residual stress state into the aluminium castings. Furthermore, a comparison with stresses induced by Rheocasting processes is underway. In fact, it is well known that Semi-Solid metal forming combines the advantages of casting and forging, solving safety and environmental problems and possibly even the residual stress state can be positively affected.
