Experimental study on surface residual stress of titanium alloy curved thin-walled parts by ultrasonic longitudinal-torsional composite millingThe International Journal of Advanced Manufacturing Technology - Tập 115 - Trang 1021-1035 - 2021
Zhiming Zhang, Jinglin Tong, Junshuai Zhao, Feng Jiao, Penghui Zai, Ziqiang Liu
The production of thin-walled titanium alloy curved surfaces is of great significance to aerospace manufacturing industry. The magnitude and distribution of residual stress are one of the important factors affecting the surface integrity of the workpiece. In order to obtain larger surface residual compressive stress, improve the surface integrity of the workpiece, and realize the fatigue-resistant...... hiện toàn bộ
Research progress of transition layer and filler wire for laser welding of steel and aluminum dissimilar metalsThe International Journal of Advanced Manufacturing Technology - Tập 119 - Trang 4149-4158 - 2022
Yaowu Zhao, Yuhong Long, Zhaoyan Li
Steel-aluminum dissimilar metal welding has a robust application demand in automobile lightweight. However, the formation of Fe-Al intermetallic compounds (IMCs) reduces the steel-aluminum welded joint’s mechanical properties (tensile strength or linear load). This paper reviews the research results of transition layer and filler wire in improving the mechanical properties of steel-aluminum laser ...... hiện toàn bộ
Variable-period feed interpolation algorithm for high-speed five-axis machiningThe International Journal of Advanced Manufacturing Technology - Tập 40 - Trang 769-775 - 2008
Yuyao Li, Jingchun Feng, Yuhan Wang, Jianguo Yang
To alleviate the feed fluctuation and to maintain a smooth feed in conventional five-axis machining, an optimal feed interpolation algorithm (look-ahead) is proposed. However, the problem arises where the segment usually cannot be interpolated exactly in an integer period because of the nonzero joint feed at the junction. To overcome this problem, and to achieve faster machining speed and higher q...... hiện toàn bộ

Experimental analysis of an asymmetrical three-roll bending processThe International Journal of Advanced Manufacturing Technology - Tập 83 - Trang 1823-1833 - 2015
Jamel Salem, Henri Champliaud, Zhengkun Feng, Thien-My Dao
The asymmetrical three-roll bending process is commonly used to manufacture cylindrical and conical sections from flat plates. The roll bending forces, the residual stresses, and the required roll bending power are influenced by material properties and process parameters, such as yield stress, plate thickness, curvature, and conicity for a truncated cone. In the present paper, an analytical model ...... hiện toàn bộ
Production control policies for a multistage serial system under MTO-MTS production environmentThe International Journal of Advanced Manufacturing Technology - Tập 83 - Trang 449-459 - 2015
Paolo Renna
A manufacturing system composed by several stages in serial system is considered. Each stage can produce several types of products from a semi-finished product. At each stage, a production control strategy is performed to release MTO and MTS orders. The MTS orders try to reduce the lead times and increase the service level for the customers. This research proposes MTS control policies observing th...... hiện toàn bộ
A method to predict possibility of arcing in EDM of TiB2p reinforced ferrous matrix compositeThe International Journal of Advanced Manufacturing Technology - Tập 86 - Trang 2837-2849 - 2016
A. B. Pandey, P. K. Brahmankar
Electrical Discharge Machining (EDM) is very popular for machining conductive metal matrix composites (MMCs) because the hardness rendered by the ceramic reinforcements to these composites causes very high tool wear and cutting forces in conventional machining processes. EDM requires selection of a number of parameters for desirable results. Inappropriate parameter selection can lead to high overc...... hiện toàn bộ
