Due to the large size and complicated features, brake discs of high-speed trains are difficult forge, so a reasonable design process die parameter prerequisites for successful forming. The flow stress 23CrNiMoV, forged-steel disc material trains, was investigated by uniaxial compression experiment on Gleeble 1500 test machine. Based obtained flow-stress data, series numerical simulation analyse...

As a traditional high energy-consuming industry, the forging industry consumes a lot of energy. The activity consuming highest energy during forging process is the forging and heating. In order to solve the problem regarding how to separate work pieces with different holding temperature intervals and combine them for charging, a group of work pieces with compatible holding temperatures are anal...

This paper describes a review of automation techniques as currently practiced in the forging and forming industry. That industry has been relatively resistant to handling automation because of the severe challenges that are faced by having typically small batch sizes, extremely challenging operating conditions in terms of temperatures and pressures and lighting conditions. The paper discusses h...

Abstract Two-way multi-axial forging was performed on a newly designed closed-die tool. The tool operated an MTS 810 material testing system. connected computer recorded force and crosshead displacement as function of time during operation. sample the four-step experiment CuE copper alloy. plastic deformation 0.8 per step, thus rate cumulative equivalent strain 3.2 by end process. speed movemen...

Editorial Forging Ahead 'All I know,' wrote Seamus Heaney, 'is a door into the dark 1 .' Me too. The world of radiology is figuratively and perhaps, on occasion, literally just that. Our game is the image, not the written word. Pretty pictures. Yet, now we increasingly find ourselves integral to the medical paradigm. This, clearly, is no reflection on us, but underpins the requirement, primacy,...

Abstract— Forging is a very complex process and the measurement of actual forces for real material is difficult and cumbersome. The main objective of this document is to use the analytical methods for measuring parameters such as load, and stress distribution of forging process and use them to make simple, reliable, fast and non-expensive simulation tools, contrary to the commercial software’s ...

High-strength steels are pre-heated in gas-fired furnaces before undergoing the open-die forging process. This process increases thermal oxidation on steel surfaces, affecting interfacial friction between ingot and anvils during deformation. Two medium carbon high-strength with different nickel contents were oxidized, mechanical characteristics of oxide layers investigated by micro nano-indenta...

This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...
