This paper proposes a hybrid physics data-driven model-based fusion framework for tool wear prediction to improve low prediction accuracy of physical model and poor interpretation of data-driven model. In this framework, physical information and local features of sensor measurement signals are used as inputs to build a hybrid physics data-driven (HPDD) model. And data mining and physics principles are effectively integrated by using unlabeled samples for data expansion. Piecewise prediction is introduced to reduce difficulty in parameter estimation. Then, in order to manage prediction uncertainty of physical information and HPDD method, two prediction results are gradually combined based on Bayesian fusion mechanism to eliminate prediction error. Finally, the effectiveness of the proposed method is verified by experiment. Compared with existing methods, this method significantly improves prediction. The mean values of root mean square error (RMSE) and mean relative error (MARE) for tool wear prediction results are respectively 2.28 and 1.85.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"28 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140202906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fitting approach for shaft sleeve assembly is usually interference fit, which requires significant contact forces. Conventional assembly methods, though focused on safety, often struggle to achieve high efficiency. Reinforcement learning can effectively select appropriate assembly actions through interaction with the environment, making it well-suited for shaft sleeve assembly tasks. Firstly, a comprehensive workflow for shaft sleeve assembly is formulated, including system initialization, insertion, push, and completion. Our research focuses mainly on the insertion process. Secondly, the core control algorithm adopts a deep reinforcement learning method based on the Actor-Critic architecture. The reward function includes safety reward, step length reward, and step reward. Safety reward ensures assembly security, while step length and step reward enhance assembly efficiency from different perspectives. Finally, real-world experiments on shaft sleeve assembly are conducted, including ablation experiments, parameter tuning experiments on reward function, and comparative experiments with conventional methods. The results of the ablation experiments and parameter tuning experiments indicate that after combining safety reward, step length reward, and step reward, the assembly effect achieves the best, verifying the effectiveness of the proposed reward function. Comparative experimental results demonstrate that our approach not only enhances safety compared to conventional methods but also significantly improves assembly efficiency, indicating the feasibility of this method.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"86 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140203179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fast thermal simulations are thus needed to plan efficient and error-free AM processes. This paper addresses a fast thermal simulation method for a novel subsea wire arc additive manufacturing (SWAAM) repair procedure. Current commercial finite element (FE) codes for typical welding and AM are computationally expensive and slow. The presented 2D finite difference approach can be used to simulate SWAAM on a damaged plate with around 70 times acceleration compared to real welding times, without the use of parallelization. Although not being able to accurately represent the temperature in close vicinity of the welding torch, the approach shows excellent correspondence with FE simulations and experiments in regions of the plate where the temperature has assumed a distribution that is largely two-dimensional. Compared with FE simulations, the approach is experimentally verified to be accurate to 10 °C within 7 s after the welding torch has passed a point on the plate. Thus, the approach can provide a measure of the global temperature field in a thin-walled structure during repair. The thermal simulation is preceded by a welding path planner, which generates appropriate paths based on slicing of a 3D surface scan of the damage that is to be repaired. Damages to equipment or non-ideal welding conditions are prevented by automatically pausing the welding if the calculated temperature in the path ahead of the welding torch exceeds a predefined interpass temperature limit.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"28 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140203201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the location datum of the film cooling holes is changed, which has an impact on the machining accuracy. The majority of pertinent studies concentrate on the rigid location approach for the entire blade, which results in a modest relative position error of the blade surface but still fails to give the exact position and axial direction of the film cooling holes of the deformed blade. In this paper, the entire deformation of the blade cross-section curve is divided into a number of deformation combinations of the mean line curve based on the construction method of the blade design intent. The exact location of the film cooling holes in the turbine blade with deviation is therefore efficiently solved by a flexible deformation of the blade that optimises the position and axial direction of the holes. The verification demonstrates that the novel method can significantly reduce both the contour deviation of the blade surface and the location issue of the film cooling holes. After machining experiments, the maximum position deviation of the holes is reduced by approximately 80% compared to the rigid location method of the entire blade, and the average value and standard deviation are also decreased by about 70%.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"1 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140202908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrical discharge machining (EDM), one of the non-traditional machining, is increasingly used. However, there were hardly any studies on the evaluation of energy consumption and carbon emissions in EDM. In this study, a quantitative assessment model of carbon emission in EDM was built based on the emission factor method. The tool electrode wear, harmless treatment of residual tool electrodes and working fluid, and electrical energy consumed by the equipment were considered in this assessment model. EDM drilling experiments were conducted to verify the effectiveness of the proposed model. The effects of pulse width, pulse interval, and peak current on machining time, surface roughness, energy consumption, and carbon emissions were analyzed. The CNC system, cooling system, and power supply consumed about 95% of the total energy. In small hole EDM drilling, the total carbon emissions from the preparation and waste residue treatment of workpiece and tool electrode were almost negligible due to the small material removal volume. The carbon emissions generated by electrical energy consumption account for about 50% of the total carbon emissions. Carbon emissions can be minimized to 72 g and energy consumption can be reduced to a minimum of 37.48 Wh when processing a small hole with the diameter of 1 mm and the depth of 6 mm by EDM drilling.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"16 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140203328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the vibration velocities are not formulated in the empirical rubbing formulae, the process damping effect in chatter stability can not be modelled. In order to simultaneously guarantee the calibration accuracy of the cutting force coefficients and solve the chatter stability with process damping, a unified ternary-mechanism model is established in this article. First, the ploughing forces corresponding to the flank edge and bottom edge are formulated as the function of the indented area and the corresponding proportion factors based on Hertz contact theory. And the static and dynamic ternary cutting forces are explicitly formulated. Second, with the aid of the static equilibrium equation together with the expression of small disturbance, the dynamic model including ploughing-based process damping is established. Third, a fast procedure to calibrate the real-time cutting force coefficients is also derived based on the inverse process of static cutting force modelling. A series of test platforms are built to verify the correctness of the calibration method and the ploughing-based process damping model. Good consistency between the predicted and experimental results in both static cutting forces and dynamic chatter tests proves that above models have better accuracy.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"1 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140202912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its great promise in design flexibility, wide application of this technology is hindered by a lack of quality assurance in fabrication parts. Melt-pool morphological characteristics are eminent indicators for manufacturing process stability and part quality. However, existing studies on melt-pool morphology focused on key geometric properties (e.g., length, width, size) extracted from melt-pool images for characterizing its variations, and tend to overlook 3D morphological variations of melt pools and ejected spatters. In this paper, we develop a multiscale modeling framework to represent, characterize, and monitor melt-pool variations through 3D morphological features, including multiscale basis function modeling of 3D melt-pool morphology and an iterative search of predominant components for sparse representation of morphological variations in melt-pool images. A case study with real-world experimental data shows that the proposed framework effectively characterizes 3D melt-pool morphological variations and provides salient features for tracking process variations, predicting melt-pool sizes, and detecting spatters. This framework is generally flexible for a wide variety of additive manufacturing (AM)applications such as melt-pool simulation, process monitoring, and anomaly detection.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":"42 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140202994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
