The quality of the rolled strips, among other factors, is strictly related to the friction conditions within the roll bite, initially unknown. The present paper proposes an accurate approach to inversely calibrate the coefficient of friction (CoF) at the roll/strip interface in a two-stands reversing cold mill (RCM) by combining numerical simulation, training of accurate regression model and a final optimization step managed by a multi-objective genetic algorithm. The process was reproduced in the virtual environment of the commercial code Abaqus by modelling both the blank and the rolls as deformable bodies. A set of simulations, arranged according to a full factorial plan, were run by changing the CoF of the first (µ1) and second stand (µ2). The discrepancy between numerical results (rolling forces and interstand tension) and the correspondent data acquired from the in-situ measurements allowed to train accurate regression models, subsequently used in an optimization managed by the MOGA-II genetic algorithm. The methodology was applied to evaluate the tribological performance of two lubricants, a natural based (GR) and a semi-synthetic (SS) one. The numerical simulations of the process highlighted a cross interaction between the rolling conditions of the two stands: in fact, the increase of the CoF in the first stand affects the interstand tension that, in turns, influences the distribution of the contact pressure in the roll bite of the second stand. Therefore, a precise calibration of the friction coefficients was possible only by looking simultaneously at the rolling forces and at the interstand tension. It was eventually demonstrated that GR lubricant showed comparable tribological performance to the SS one but with a non-negligible reduction on the rolling forces and a sensibly lower impact from the environmental perspective.</div></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"59 ","pages":"Pages 223-234"},"PeriodicalIF":4.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143799293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies in milling with this kind of tool focused mainly on multidirectional (MD) FRP composites. However, it is well known that fiber orientation is a critical parameter in FRP machining. Accordingly, this paper presents a machinability analysis of unidirectional (UD) FRP composites in edge trimming at various fiber orientations, for the specific case of burr tools. Edge trimming experiments are conducted using glass fiber reinforced polymer (GFRP) composites and diamond-coated burr tools. For each machining test, cutting forces, machined surface temperature and surface quality are quantified, as well as defects on external plies, which are characterized with a device specifically developed for this purpose. The results demonstrate that all the parameters are affected greatly by fiber orientation. The maximum temperature rise and the resultant force generally move in the same direction. The surface irregularities, and the maximum rise in temperature, move globally in opposite directions. Uncut fibers on the lower face of the workpiece are related to axial forces and may be facilitated by high temperatures. Moreover, the effect of fiber orientation on cutting forces in the workpiece plane, machined surface temperature and surface quality is analogous to previous literature on orthogonal cutting.</div></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"59 ","pages":"Pages 194-206"},"PeriodicalIF":4.6,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laser powder bed fusion (LPBF) is a promising additive manufacturing technique for fabricating complex heat-dissipation structural components. However, pure aluminum has important application prospects in the field of heat dissipation, but its lower melting point and laser absorption rate compared to alloys result in difficult processing characteristics during LPBF, which remains poorly understood. This work systematically investigated the influence of laser processing on the multi-scale microstructural features and the synergistic effect on the mechanical and thermal performance of LPBF-fabricated pure Al parts. Results revealed that increasing the scanning speed from 0.6 m/s to 1.2 m/s leads to refined grains, increased dislocation density, decreased maximum orientation density along &lt; 001 &gt; direction, and a higher fraction of high-angle grain boundaries. These microstructural changes, coupled with the evolving porosity content, result in an initial enhancement followed by a decline in both the ultimate tensile strength and elongation of the fabricated parts. The thermal conductivity gradually decreases with the increase of scanning speed, which is due to the increased grain boundaries, dislocations, and stress that enhance the scattering behavior of electrons and phonons. The established processing-microstructure-property relationships provide critical insights for developing LPBF-processed Al based materials with an optimal balance between mechanical and thermal performance, enabling their widespread applications in structural and thermal management components.</div></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":"59 ","pages":"Pages 207-222"},"PeriodicalIF":4.6,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It may be applied to fabricate components of functional materials such as the binary Mg<sub>2</sub>Si alloys with appropriate parameter optimization for energy harvesting applications. The L-PBF processing of such a material requires critical control over the input laser power and scan speed to minimise the structural defects in the end product. We developed a Computational Fluid Dynamics (CFD) model in MATLAB to simulate the thermal profiles of the dynamic molten pool to modulate the applied laser power and the scan speed. The material’s melting point and the conventional sintering temperature were used as the baseline numbers to scrutinize the suitable laser parameters. The CFD modeled laser parameters were tested to fabricate L-PBF processed Mg<sub>2</sub>Si and the conventional sintering temperature of 1173 K was found to be a better limiting criterion than the melting point to prevent excessive balling and Mg vaporization. The fluidic flow velocity and its effect on the melt pool dynamics were observed experimentally. The microstructural variations in such materials are known to affect their thermoelectric performance, and the high cooling rate during the solidification in the L-PBF process favors dendritic growth, which differs from the conventionally fabricated samples possessing equiaxed grains. The microstructure evolution from the rapid solidification of the melt pool was predicted using the phase field analysis considering the effects of perturbation and the strength of anisotropy. A computational domain was simulated with an initial nucleation site of diameter 0.35 µm, and the directional dendritic growth patterns for different laser power and scan rates were obtained and analyzed. A comparable interdendritic spacing between the simulated primary dendritic arms (0.46 µm) and that measured within the L-PBF processed sample (0.57 µm) as seen under a Scanning Electron Microscope (SEM) is obtained, indicating the model’s efficacy in simulating the possible growth mechanism.

Machine learning (ML) is used to predict VEs under no load and stable thermal conditions. Data is acquired using a scale and master ball artefact (SAMBA) and on-machine touch probing. A general process for determining the minimum number of balls required to generate data to satisfactorily train an ML model is proposed.

The NanoCyl can evaluate the three main components of cylindricity, as defined by ISO 12180–1: cross-section deviations through EST, median line deviations from harmonic signal analysis, and radial deviations using synchronised measurements from opposite probes.
