Although various heating technologies have been applied as RHCM techniques, low energy efficiency has caused productivity to decrease. To improve this issue, the RHCM process was implemented using a CNT web film for more efficient heating. A multilayer structure module was designed to apply the CNT web film to a full-size injection mold. The RHCM process was implemented by designing stable heat transfer and electrical insulation through a multilayer structure module. When power was applied, the temperature rose quickly, with the highest heating rate reaching 41 °C/s at 40 kW, and the highest temperature achieved at about 300 °C. The temperature uniformity and stability were tested on 6 points of the cavity surface, and an average of 97% temperature uniformity and stability was observed during heating. In production testing of the Center Fascia (CTR.FASCIA), which is an internal automobile part made of polycarbonate/polybutylene terephthalate composites, an RHCM process was conducted. The width and depth of weld lines in the molded products were eliminated, and a 26% improvement in glossiness and surface quality was observed compared to the conventional injection molding process (CIM). CNT web film is a versatile and flexible material that can be applied in various forms, and it has been confirmed that by utilizing this material to create a multilayer structure module, the RHCM process can be performed reliably.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140127303","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 Gaussian heat source model was applied to predict the temperature on the surface of the crankshaft connecting rod journal. Transient thermal analysis and investigation of material phase transformation were employed to explore the mechanism of grinding burns. The interaction effects among grinding parameters were analyzed using the Box-Behnken design, and a multiple linear regression equation was established for response surface optimization. The results demonstrated that applying the Gaussian heat source model and response surface optimization yielded the optimal solution, with a maximum deviation of 1.37% between the simulation and optimization results.

To evaluate the effect of laser separation distance on the mechanical properties of T joints, 2219 aluminum alloy double-sided laser beam oscillation filler welding experiments with different laser separation distances were conducted in this work. With laser separation, the symmetry of fusion zone was weakened. The keyhole stability at latter welding side was weakened. The number of pores in the T joint increased. The laser separation distance promoted the formation of porosity at latter welding side and the formation of porosity in the stringer. Most of the cracks in the tensile tests at the weld foot propagated in the partially melted zone. Porosity has no significant influence on the tensile strength of T joints. When laser separation distance was 3 mm, the mechanical performance of T joint was the best. The hoop tensile strength was 370.0 MPa. The T-pull tensile strength was 309.5 MPa. Based on the results of tensile strength testing, the mechanical performance of T joints welded by double-sided laser beam oscillation filler welding did not deteriorate with the laser separation distance less than or equal to 3 mm, which showed a good tolerance of laser separation distance for the welding process.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140127194","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 precision ECM could be processed only if the initial roundness error is decreased or eliminated and the inter-electrode gap (IEG) becomes steady after reaching an equilibrium state. However, a constant voltage is generally used in ECM process. And a long time and a large allowance are required to level the profile error of workblank if the initial profile error is large. In this study, the focus herein is on the acceleration of the leveling process of the rotary workpiece. A counter-rotating electrochemical machining (CRECM) process method with a variable voltage is proposed to improve the leveling ability. For a rotary workpiece with elliptical contours, the machining voltage can be dynamically adjusted based on the IEG through the approximate regulation of sine waves according to modeling-based analysis. The method aims to improve the leveling ability by expanding the difference in the magnitude of electric current between the high and low points on the profile of the anode workpiece under different voltages. The results of experiments confirmed that the proposed method significantly reduced the leveling time from 36 to 7 min (by 81%), and the depth of dissolution of the highest point on the profile from 1.68 to 0.45 mm while reducing the roundness error from 0.5 to 0.05 mm. The leveling ratio increased from 0.26 to 0.99.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140129920","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 method consists of measurements of roundness profiles in several cross-sections of the cylindrical surface. Usually, the distance between subsequent cross-sections is equal. The number of cross-sections used depends on the required accuracy of the assessment of the cylindricity deviation. If one wants to get only rough estimation of the cylindricity deviation, then the measurement can be made in a few cross-sections only. However, if the required measurement accuracy is high, measurements should be carried out in a large number of cross-sections. The consequence of taking the measurements in a large number of sections is significant extension of the measurement time. In this work, an adaptive method of measuring cylindricity is proposed, the purpose of which is to ensure the required measurement accuracy while reducing the necessary number of cross-sections in which roundness profile measurements should be conducted. The proposed strategy is iterative and it is based on carrying out measurements in the cross-sections of the measured part. The proposed method implies two criteria: the correlation coefficient and the predicted values of the form deviations in the non-measured areas of the measured part. The paper presents the fundamentals of the method and the selected results of its practical verification.

However, the conventional cutting strategy, in which the laser beam maintains a stationary posture along the hole path, lacks flexibility and fails to effectively leverage processing tolerances. In this study, we conduct a thorough analysis of the kinematics of a six-axis redundant laser cutting machine and resolve through a decoupling method with singularity management. We propose an innovative conic posture cutting strategy for 3D laser hole-cutting with thin materials. This approach adopts the geometry of a cone as the posture while cutting the hole path. In order to obtain the optimal vertex of the cone while minimizing the taper error generated by the conic posture and kinetic energy consumption of the actuators during motion, we formulate a multi-objective optimization problem and solve it using a genetic algorithm. Furthermore, we enhance the optimization by adopting a time minimization approach. Through the implementation of a B-pillar workpiece cutting experiment, we have successfully validated the credibility of our proposed cutting strategy, thereby demonstrating an enhancement of time on 26 hole-cutting paths.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140117543","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}

To better optimize and control the grinding process of the grinding head, this paper proposes a grinding force prediction method of the grinding head that combines surface measurement, statistical analysis, and finite element method (FEM). Firstly, a grinding head surface measurement system is constructed according to the principle of focused imaging. The distribution model of abrasive grains in terms of size, spacing, and protruding height has been established by measuring and counting the characteristics of abrasive grains on the surface of a real grinding head. Then, the undeformed chip thicknesses when the abrasive grains are cut are analyzed in depth, the material model of abrasive grains and workpiece is established, and the cutting process of abrasive grains with different characteristics on the surface of the grinding head is analyzed by finite element simulation. A single abrasive grain grinding force model is obtained. Finally, the grinding force prediction of the grinding head was realized by combining finite element simulation with grinding kinematics analysis. In addition, grinding experiments with different grinding parameters were conducted to verify the grinding force prediction model. The results show that the predicted grinding force of the grinding head is in good agreement with the experimental values. The average error of tangential grinding force is 7.42%, and the average error of normal grinding force is 9.77%. This indicates that the grinding force prediction method has good accuracy and reliability.","PeriodicalId":50345,"journal":{"name":"International Journal of Advanced Manufacturing Technology","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140126453","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 microstructure and mechanical properties of 304 WAAM entity and Ni60B coating were systematically investigated. The results show that a good metallurgical bond is achieved between the Ni60B coating and 304 substrate.

Slender columnar crystals and cellular crystals coexist in the 304 bonding region, while the bottom of the Ni60B coating consists of plane crystal and columnar crystals. Both molten pools appear to have a haphazardly growing dendrite structure inside. Compared to the 304 substrate, the hardness of Ni60B coating increases by 2.76 times, and the friction and wear mass loss is only 10.54% of the 304, significantly improving the wear resistance of the 304 substrate.
