Abstract null null The next-generation medical implants require locally customised biomechanical behaviour to echo the properties of hard tissues, making additive manufacturing (AM) an ideal route due to its superior manufacturing flexibility. AM of titanium alloys with designed porosity is the mainstream for artificial implants, which, however, hardly balance the strength-modulus combination. Here a martensitic TiNi biomaterial with low modulus and asymmetric mechanical behaviour that mimics hu...

Abstract Directed energy deposition (DED), also known as laser cladding, is one type of additive manufacturing where a high-power laser combined with a coaxial powder delivery system is used to produce metal components layer-by-layer. Despite many advancements in DED, little work has been accomplished in in-situ estimation of mechanical properties, such as Young's modulus and Poisson's ratio, during the DED process. In this study, an in-situ mechanical properties estimation technique was develop...

Abstract The research and application of high speed metal cutting (HSMC) is aimed at achieving higher productivity and improved surface quality. This paper reviews the advancements in HSMC with a focus on the material removal mechanism and machined surface integrity without considering the effect of cutting dynamics on the machining process. In addition, the variation of cutting force and cutting temperature as well as the tool wear behavior during HSMC are summarized. Through comparing with con...

Abstract Achieving small-radius bending of difficult-to-form tubular materials with large-diameter, thin-walled (LDTW, D/t > 20) geometry — as well as the properties of high-strength poor-hardening (HSPH) — is a continual target and challenging issue in the aerospace, marine, and healthcare industries. Based on the theoretical analysis of neutral layer shifting reconstruction (NLSR) by positively utilizing the temperature-dependent tension-compression (T-C) asymmetry of tubes, an innovative diff...

Abstract Directed energy deposition (DED) additive manufacturing (AM) is receiving growing attention in many applications, such as repair, remanufacturing, and fabrication of functionally graded structures. However, the laser-matter interactions and melt pool dynamics in laser DED with powder flow are still unclear, particularly in how pores form and flow inside the melt pool during the process. Understanding the porosity formation mechanisms is critical in the qualification, certification, and ...

Abstract The motion accuracy of a linear axis is represented by the geometric errors defined in the current standards. However, the geometric errors are the local properties for the error-included motion of the moving component and their values are related to the position of the measured function point or line. This will cause uncertainties for the results of an accuracy test. Thus, a new invariant approach is presented for the motion accuracy test and motion error identification of a linear axi...

Abstract null null The accurate prediction of chatter stability in milling operations is a continuous pursuit of manufacturing engineering. Physical-based stability analysis methods suffer from inaccurate model parameters, while data-driven methods lack generalisability and physical interpretability. This study proposes a physics-informed Bayesian inference framework for milling stability analysis. The framework leverages experimental data to infer the distribution of model parameters for probab...

Abstract Micro electroforming is a promising electrodeposition-based precision replication technique for the fabrication of microstructured moulds. In this process, a poor mass transfer inside the micro structure with a high aspect ratio significantly affects the replication accuracy of the mould. In this paper, a novel star pattern with a continuously changing line width in the range of 20–320 μm, corresponding to a variable aspect ratio of 0.16–2.5, is firstly proposed for the assessment of ma...

Abstract In milling, two different self-excited vibrations have been reported; regenerative and mode coupling chatter. The regenerative chatter mechanism has been extensively studied and validated with tests whereas mode coupling chatter mechanism was reported a long time ago for threading operations. The presented mode coupling chatter models were based only on current vibrations of the system but not on the delayed vibrations. With the increase in the research carried out on robotic milling op...
