The point tip of the twist drill penetrates beyond the bone before neurosurgeons can rely on their haptic senses to detect the drop in thrust force and retract the drill. The tip of an over-penetrated twist drill may damage the brain or spinal nerve underneath the bone. The bone drilling devices with automatic retraction have the same issue of sharp twist drill over-penetration due to the small force drop at the point of penetration. This research designs a flat bottom drill capable of creating a flat bottom hole in bone drilling to overcome the over-penetration issue. This flat bottom drill has a sudden thrust force drop as a signal to stop and retract the drill without penetrating the bone. The flat bottom drill may also use the color change on the bottom surface of the drilled hole for visual feedback for retraction. The design and geometric features of the flat bottom drill are first introduced. A mathematical model is developed to calculate the rake and inclination angles on cutting edges. Four flat bottom drills are designed, manufactured, and evaluated in drilling the ex-vivo bovine bone. Results of the drilling thrust force and torque as well as the chip formation are compared with those of the twist drill. The flat bottom drill has demonstrated to be much more sensitive than the twist drill in penetration detection by sensing the sudden drop in thrust force at the end of bone drilling.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"144 ","pages":"Pages 326-338"},"PeriodicalIF":6.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is prone to internal defects, such as lack of fusion porosity and cracks, that may compromise the mechanical and microstructural properties, thereby, impacting the overall performance and reliability of manufactured components. This study focuses on in-situ monitoring and characterization of melt pools closely associated with internal defects like porosity, aiming to enhance defect detection and quality control in DED-printed parts. Traditional machine learning (ML) approaches for defect identification require extensive labeled datasets. However, in real-life manufacturing settings, labeling such large datasets accurately is often challenging and expensive, leading to a scarcity of labeled datasets. To overcome this challenge, our framework utilizes self-supervised learning using large amounts of unlabeled melt pool data on a state-of-the-art Vision Transformer-based Masked Autoencoder (MAE), yielding highly representative embeddings. The fine-tuned model is subsequently leveraged through transfer learning to train classifiers on a limited labeled dataset, effectively identifying melt pool anomalies associated with porosity. In this study, we employ two different classifiers to comprehensively compare and evaluate the effectiveness of our combined framework with the self-supervised model in melt pool characterization. The first classifier model is a Vision Transformer (ViT) classifier using the fine-tuned MAE Encoder’s parameters, while the second model utilizes the fine-tuned MAE Encoder to leverage its learned spatial features, combined with an MLP classifier head to perform the classification task. Our approach achieves overall accuracy ranging from 95.44% to 99.17% and an average F1 score exceeding 80%, with the ViT Classifier outperforming the MAE Encoder Classifier only by a small margin. This demonstrates the potential of our framework as a scalable and cost-effective solution for automated quality control in DED, effectively utilizing minimal labeled data to achieve accurate defect detection.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"145 ","pages":"Pages 11-21"},"PeriodicalIF":6.1,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the presence of defects has a significant impact on the implantation effect. The stability and flow state of the molten pool, which is controlled by processing parameters, are of great significance for the formation of defect-free components fabricated by laser powder bed fusion (LPBF). To date, the relationship among processing parameters, molten pool evolution, and defects has not been established yet. In this paper, single-track and bulk samples of pure Ta were fabricated using LPBF technology, and a powder-resolved computational fluid dynamics (CFD) model of pure Ta was established to study heat transfer and fluid flow characteristics in the molten pool. The effects of processing parameter variations on the types and quantities of defects were systematically analyzed, and the formation mechanisms of defects were revealed by combining simulation results of molten pool evolution under different parameters. The results show that increasing the laser energy density would promote higher temperature and faster velocity fields within the molten pool. Under the elevated temperature field, the spreading speed was faster than the solidification speed of the molten Ta, and the melt of powders was more sufficient, resulting in fewer keyholes after solidification. Under the rapid velocity field, the Marangoni convection was intense, which would lead to difficulty for bubbles to escape and an increase in gas pores. The coordination of temperature and velocity fields in the molten pool determined the types and quantities of defects in LPBF samples. Unmelted Ta powders acted as barriers to prevent the epitaxial growth of grains, depending on the melting state. This article presents a profound analysis of processing parameters, defects, molten pools, and microstructure changes, and is expected to provide scientific and theoretical support for the exploration of LPBF processing parameters and the causes of changes in the microstructure and properties of LPBF samples.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"144 ","pages":"Pages 311-325"},"PeriodicalIF":6.1,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work prepared multi-material structures of immiscible CuSn10-18Ni300 with an interlayer IN718 vertically, using two reversed building sequences by LPBF, to compare their interfacial segregation and microstructure, resulting mechanical properties, and behind mechanisms. Sequence I printed CuSn10 onto 18Ni300 via IN718; Sequence II printed 18Ni300 onto CuSn10 via IN718. Both sequences produce three shapes of interfacial macrosegregation (shape of beaches, peninsulas, and islands), but following different thermodynamic mechanisms. The microstructure highlights the traces related to those macrosegregation shapes, verifying the mechanism, and interestingly, the cracks are even healed by upper CuSn10 under Sequences I, benefiting interfacial bonding. Besides, a transition of cellular-columnar grains from 18Ni300 to IN718 is observed under both sequences, while less visible molten pool boundaries are seen in CuSn10. Those IN718 columns are either 〈001〉 oriented along the building direction under Sequence I, or randomly oriented under Sequence II with reduced temperature gradients. Finally, microhardness evolution and tensile behaviours successfully evaluate the structural reliability under two building sequences. A favourable ductile fracture within the CuSn10 region is produced with strength of 395 ± 29 MPa and elongation of 16.6 ± 2.6 % under Sequence I, benefiting from the healed cracks and enhanced interfacial bonding. Conversely, Sequence II causes a brittle fracture within the interlayer with lower tensile properties, due to the remaining cracks and microstrain.

A common example is biofouling, where biofilms form through extracellular substances and microbial cell matrices. Beyond reducing the efficiency of machines and components, fouling can significantly shorten the lifespan of materials by accelerating corrosion. Additive manufacturing (AM) is a collection of novel processes for fabricating tridimensional parts layer by layer. Among AM technologies, powder bed fusion using a laser-based system (PBF-LB) is widely used for processing pure metals and alloys due to its ability to create highly complex geometries. This capability enables the production of components with enhanced efficiency, such as heat exchangers, food mixers, and ship propellers – structures often exposed to biofouling. This study explores the effects of different gas protective atmospheres (Ar and N₂) on the microstructure, thermal properties, surface characteristics, and densification of stainless steel bulk samples fabricated via PBF-LB over a large processing window. When identical processing parameters (layer thickness, laser power, scanning speed, hatch spacing, scan rotation, and scan pattern) were used, variations in energy density due to atmospheric differences influenced thermal properties, grain size distribution, crystallographic orientation, nitrogen content, and surface roughness of bulk parts. These changes suggest that antifouling properties could be enhanced by selecting appropriate processing atmosphere. Antifouling surfaces are critical in industries such as naval, pharmaceutical, and food industries where microbial accumulation can compromise performance and hygiene.
