Influence of die geometry on self-piercing riveting of aluminum alloy AA6061-T6 to mild steel SPFC340 sheets
Springer Science and Business Media LLC - Tập 7 - Trang 209-220 - 2019
The self-piercing riveting (SPR) process was used to join 2.0-mm-thick aluminum alloy 6061-T6 and 1.2-mm-thick mild steel SPFC340 sheets. SPR joints produced with a conventional flat-bottom die and conical-section dies were investigated both experimentally and numerically. Lap shear tests were conducted under quasi-static conditions to evaluate the load-carrying capability of these SPR joints. The...... hiện toàn bộ

Mechanical properties of U-0.95 mass fraction of Ti alloy quenching and aging treatment: a first principles study
Springer Science and Business Media LLC - Tập 3 - Trang 244-251 - 2014
First principles plane wave pseudopotential method was executed to calculate the mechanical properties with respect to the uranium-0.95 mass fraction of titanium (U-0.95 mass fraction of Ti) alloy for quenching and aging, including the elastic modulus, the value of shear modulus to bulk modulus (G/B) and the ideal tensile strength. The further research has also been done about the crack mechanism ...... hiện toàn bộ
Multi-objective resource optimization scheduling based on iterative double auction in cloud manufacturing
Springer Science and Business Media LLC - Tập 7 - Trang 374-388 - 2019
Cloud manufacturing is a new kind of networked manufacturing model. In this model, manufacturing resources are organized and used on demand as market-oriented services. These services are highly uncertain and focus on users. The information between service demanders and service providers is usually incomplete. These challenges make the resource scheduling more difficult. In this study, an iterativ...... hiện toàn bộ
Machining of circular micro holes by electrochemical micro-machining process
Springer Science and Business Media LLC - Tập 1 - Trang 314-319 - 2013
Machining of micro holes with micro electrochemical machining (micro ECM) process has been carried out with an indigenously developed set up. This paper describes relevant problems and solutions for the circular micro holes machining process on 304 stainless steel sheets with 60 μm thickness using high speed steel cylindrical tool of diameter 500 μm and using dilute H2SO4 as electrolyte. The taper...... hiện toàn bộ
Precision wire electrochemical machining of thick structures in powder superalloy René 88DT using a partially insulated tube electrode
Springer Science and Business Media LLC - Tập 11 - Trang 618-635 - 2023
Wire electrochemical machining (WECM) is a potential method for manufacturing macrostructures from difficult-to-cut materials, such as turbine slots, with good surface integrity and low costs. In this study, a novel tube electrode with array holes in the front and insulation in the back was applied using WECM to improve the machining precision and efficiency. Additionally, assisted by an immersion...... hiện toàn bộ
Experimental technique to analyze the influence of cutting conditions on specific energy consumption during abrasive metal cutting with thin discs
Springer Science and Business Media LLC - Tập 10 - Trang 260-271 - 2021
Specific energy consumption is an important indicator for a better understanding of the machinability of materials. The present study aims to estimate the specific energy consumption for abrasive metal cutting with ultra-thin discs at comparatively low and medium feed rates. Using an experimental technique, the cutting power was measured at four predefined feed rates for S235JR, intermetallic Fe-A...... hiện toàn bộ
Surface integrity evolution of machined NiTi shape memory alloys after turning process
Springer Science and Business Media LLC - Tập 9 - Trang 446-456 - 2021
Owing to their shape memory effect and pseudoelasticity, NiTi shape memory alloys (SMAs) are widely used as functional materials. Mechanical processes particularly influence the final formation of the product owing to thermal softening and work-hardening effects. Surface integrity is an intermediate bridge between the machining parameter and performance of the product. In this study, experiments w...... hiện toàn bộ
Bionic tracking method by hand & eye-vergence visual servoing
Springer Science and Business Media LLC - Tập 4 - Trang 157-166 - 2016
Animals rotate their eyes to gaze at the target prey, enhancing the ability of measuring the distance to the target precisely for catching it. These animals, visual tracking includes the triangular eye-vergence control and their body’s motion control by visual servoing. The research aims to realize a bionic robot tracking performance, in which the body links moves together with eyes’ view orientat...... hiện toàn bộ
Real-time process control of powder bed fusion by monitoring dynamic temperature field
Springer Science and Business Media LLC - Tập 8 - Trang 380-391 - 2020
This study aims to optimize the uniformity of the temperature field during sintering to improve part performance. A temperature-field monitoring system is established based on an infrared thermal imager and the temperature field data obtained during the sintering of a part can be measured in real time. The relationship among the sintering temperature field, sintering process parameters, and part p...... hiện toàn bộ
