Therefore, it is necessary to optimize the stacked assembly of the multi-stage rotor to improve assembly quality. In this paper, the Pareto-optimal schemes combining multi-objective optimization algorithms for stacked assembly of multi-stage rotors are proposed. First, the error propagation model for stacked assembly of multi-stage blisks based on tensor coordinate transformation is deduced. Taking blisk assembly phase as the design variable, the mathematical descriptions of geometric error and unbalance of the multi-stage rotor assembly are then established. The stacked assembly problem of the multi-stage rotor is formulated mathematically as a multi-objective optimization problem. The minimum geometric error and the minimum unbalance of multi-stage rotor are considered as optimization objectives. The Pareto-optimal assembly schemes are then solved based on the elitist non-dominated sorting genetic algorithm (NSGA-II). The simulation analysis and experimental study for the Pareto-optimal assembly schemes of multi-stage rotor are performed. Results show that compared with random stacked assembly, the geometric error is reduced by 40.6%, and the initial unbalance is reduced by 35.7%. The Pareto-optimal assembly schemes proposed in this paper can effectively improve stacked assembly quality of multi-stage aeroengine rotors.</p></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140906480","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}

However, it imposes greater demands on the computational efficiency, accuracy, and stability of the algorithm. In this paper, a real-time path planning method based on frame feature extraction and chronological feature optimization is proposed for the milling of attached frame-skin. The method uses a line laser to scan the surface features of both skin and frame structures, facilitating real-time extraction of feature structures. Periodic calculations of position and posture are conducted based on the time series, and a non-fitting method is used to generate a smooth and high-precision machining trajectory.

The plasma pressure during the workpiece heating phase alters the vaporization phenomenon and melt ejection, warranting an in-depth understanding. In light of this, the current work proposes a two-dimensional (2-D) multiphysics numerical model of the melt pool hydrodynamics during EDMM. The model incorporates thermal evolution along with the effects of active plasma pressure during the heating phase of the substrate with the help of a coupled thermo-fluidic model. The simulation results reveal the predominant role of plasma pressure on the crater morphology evolution, plasma flushing efficiency (PFE) and recast layer thickness (RLT).

For the non-destructive detection of these damages also known as grinding burns, micromagnetic methods have found increasing interest. Existing studies on the detectability of grinding burn by Barkhausen noise evaluation point out the need for a combination of different characteristic values to distinguish between damage-free surfaces and different pronounced damages. Besides Barkhausen noise, the 3MA-II-method offers three additional measurement techniques that were also investigated in this study. Results show the potential of a combination of Incremental permeability and Harmonic analysis for the detection and distinction of different classes of grinding damages. On the other hand, no clear definition exists to categorize different levels of damages. The classification provided by the observed grey-scale after nital etching is often used, which is rather subjective and cannot be quantitatively described in terms of surface-near properties. Therefore, the present study gives a new attempt to define a parameter that describes quantitatively the existing surface state and its level of damage based on X-ray diffraction analysis. It describes the surface state characterized by the peak width, related to hardness and residual stresses in one single parameter. The investigations show that this approach could be validated for different workpieces and heat treatment conditions, and could allow a quantitative classification of damages thus making non-destructive analysis easier to apply.</p></div>","PeriodicalId":56011,"journal":{"name":"CIRP Journal of Manufacturing Science and Technology","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1755581724000543/pdfft?md5=bc85ab860ea54e4ea3d0329b0c525fa2&pid=1-s2.0-S1755581724000543-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140554643","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}

Advances in modeling of machining-induced residual stresses are fundamental to achieve more accurate predictions. Due to the low computational efficiency and the lack of consideration of the whole residual stress formation process, a framework to simulate the residual stress in the machining of Ti-6Al-4 V titanium alloy using CEL (Coupled Eulerian and Lagrangian) and Lagrangian approaches is proposed. A model of the cutting and workpiece unloading processes is simulated using CEL approach and explicit time integration scheme. Then, a model of the cooling process of the workpiece is developed in order to calculate the residual stresses. To improve computation efficiency and to reduce the effects of cumulative errors, this model is simulated using Lagrangian approach and implicit time integration scheme. Data transfer between these two models is performed by combining a strategy of data transfer and mesh rebuilding. The cutting force and residual stress are obtained by simulation with average errors of 18% and 21%, respectively. The predicted and measured thicknesses of the layer are reasonable well predicted. The computational time of proposed approach can be greatly reduced from 81 h to 5.3 h by comparison with traditional one.
