Experimental investigations, in which stainless steel AISI 301 was pre-immersed in liquid nitrogen for 12 hours and then subjected to static tensioning at normal temperature, report new findings on the combined effect of dynamic non-equilibrium …
Accurate and timely productivity prediction is critical in manufacturing, where uncertainties from operator variability, machine failures, and urgent orders frequently disrupt production schedules. Conventional approaches, such as discrete event …
The long-term durability of dissimilar material joints is critical for a wide range of engineering applications, where hybrid structures are increasingly produced by additive manufacturing. However, the effects of ageing on these joints remain …
Friction stir welding (FSW) is widely used for joining high-strength aluminum alloys in structural and fatigue-critical applications due to its solid-state nature and ability to produce defect-free joints. However, the influence of FSW on local …
GCr15 is mainly used as bearing ring material. In the traditional precision bearing machining method, the control of grinding force and grinding temperature (GF>) often depends on operator’s “experience”, and its measurement method is quite …
In auto-body assembly, accurate detection of key dimensional points is essential for reliable gap and flush measurement, especially under noise interference and data imperfections. This paper proposes a robust and generalizable framework for gap …

The hemispherical resonator gyroscope (HRG) is a high-performance gyroscope widely used in next-generation strapdown inertial navigation systems due to its exceptional accuracy, ultra-long lifespan, and high reliability. The core component, the …
To provide researchers with a deeper understanding of and solutions to the prominent deformation control challenges in milling of large metal thin-walled components (LMTWC), this paper focuses on the milling of these components and systematically …
Artificial intelligence (AI) and additive manufacturing (AM) have propelled the next wave of technological innovation by integrating data-driven intelligence with design freedom, thereby enabling adaptive, efficient, and multifunctional systems.
Due to the excellent nonlinear optical properties and high damage threshold of Potassium Dihydrogen Phosphate (KDP) crystal, it is critical for high-power laser systems and inertial confinement fusion. Chemical mechanical polishing (CMP), which …
Aircraft assembly quality has a significant impact on aircraft performance, service life, and cost-effectiveness. Riveting is an important way of aircraft assembly. However, it is difficult to realize automatic riveting assembly due to the narrow …
This study investigates the use of machine learning to predict bead geometry in cold metal transfer (CMT)–based wire-arc additive manufacturing (WAAM) of SS410 martensitic stainless steel. A dataset comprising 50 experimentally deposited single …
The paper deals with the problem of numerically simulating the formation of cracks in the axial zone of elements formed by cross wedge rolling (CWR). Experimental research has shown that the size of such cracks depends on both the forming …
Despite electrical discharge machining (EDM) is widely used in the processing of Ti-6Al-4V, this process forms recast layer on the machined surface, severely impacting the service life of parts. Therefore, the removal of the recast layer is …
Aiming at the core problem of edge electric field concentration-induced uneven electric field distribution which leads to poor roundness of micro-dimple formation and insufficient machining consistency in Masked Jet Electrochemical Machining …
Localised damage and ductile fracture are critical factors that limit the formability of sheet metals; therefore, their accurate prediction represents a key challenge in manufacturing. In this paper, the Lemaitre ductile damage model is used to …
The transient phase of cutting is the term used to describe the conditions during which the material processing by the cutting edge transitions from ploughing-dominated deformation to shear-dominated, stable chip formation. The transient phase …
Accurately measuring the rotor’s inner diameter in industrial manufacturing often faces several challenges, including perspective distortion, edge defects, and extraneous concentric circle patterns on the rotor surface. To address these issues …
