First, according to the characteristics of the problem, a strategy for determining the group to be outsourced is considered to generate the promising initial solutions. Second, a two-stage co-evolutionary method is used to explore the solution space in depth. In the first stage, a hybrid local search (HLS) is proposed to obtain more extreme solutions. In the second stage, the reference points adaptation mechanism is employed to enhance the global search capability of the algorithm, which can select high-quality solutions. These two stages are working cooperatively during the iterative process so that the population evolves towards the true Pareto front. In addition, an energy saving strategy based on idle time is proposed to better optimize TEC.

Micro-injection molding (μIM) is a viable method for producing BCS with precise geometries and surface finishes. Yet, the inherent complexities of BCS geometry and the poor melt flow index (MFI) of material present significant obstacles to successful μIM fabrication. In this study, poly-lactic acid (PLA), was modified with triethyl citrate (TEC), a bio-based plasticizer, to enhance its MFI and processability. A comprehensive characterization of the PLA-TEC formulations was conducted, encompassing mechanical strength, thermal stability, and rheological behavior, to optimize material performance for μIM. Subsequently, process parameters were optimised utilising response surface methodology to mitigate manufacturing defects such as underfilling and flash formation, ensuring the production of high-quality BCS.

In the literature, most of the stability models consider single-point contact with shallow axial cutting depths, i.e., point milling, where the mode shape dependent dynamic response is ignorable. On the other hand, as far as high depth milling processes, i.e., flank milling, are concerned there is a line of contact along the axial direction of the milling tool, rather than a single-point of contact. Consequently, mode shape dependent dynamic response turns out to be significant for accurate prediction of stability limits. In this study, the axial variation in the frequency response function (FRF) of the milling system is considered in prediction of stability diagrams. The novel contribution of this study is the experimental verification of the proposed stability model by using a practical workpiece dynamics model.

However, slicing thinner 4H-SiC wafers using diamond wire sawing (DWS) process generates significant heat due to the extended contact length between the diamond wire and work material. This heat adversely affects the surface quality of as-sawn wafers, accelerates diamond wire wear, and poses challenges in accurately measuring the sawing temperature due to the heat dissipation through the unsliced ingot thickness. To address this, the study employed a rocking mode sawing strategy to mitigate the temperature rise caused by the prolonged contact length, while Fourier’s thermal conduction law and finite element analysis (FEA) were employed to accurately evaluate the sawing temperature. The study compares the measured sawing temperatures under rocking mode and traditional sawing conditions with Fourier’s and FEA simulations. Additionally, the effect of sawing temperature on the surface quality of the as-sawn wafer and diamond wire wear has been examined. Results demonstrate that the rocking mode sawing strategy effectively minimizes sawing temperature by 8.266 % in contrast to the traditional sawing process, attributed to its reduced contact length. Fourier’s thermal conduction law analysis proved instrumental in accurately determining sawing temperature.

A robotic drilling system was used to study both ideal and non-ideal boundary conditions. Under ideal boundary conditions, optimal drilling parameters were identified: a cutting speed of 85 m/min and a feed rate of 0.01 mm/rev for CFRP, and 60 m/min with 0.05 mm/rev for AA7075-T6. Therefore, parameter switching strategies were implemented to improve hole quality at the material transition zone. Then, under non-ideal boundary condition, variable clamping forces (0 N, 250 N, and 400 N) were applied by the robot's end effector, demonstrating that higher clamping forces significantly reduce interlayer gaps, leading to up to 60.27 % reduction in entry burr and 16.10 % decrease in delamination factor.

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}

Cutting tools with specific geometries, such as burr tools with many pyramidal teeth, help to reduce this type of defect. 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}
