Notice of RetractionNumerical simulation and experiment on precision forging of driven spiral bevel gear
In this paper, the numerical simulation of precision forging on driven spiral bevel gear was explored based on its physical simulation. The forming stage and the metal flow characteristic were analyzed; thereby the process of precision forging was designed. The material was 20CrMnTi and the equipment was friction press. The workblank of driven spiral bevel gear was manufactured successfully at 950°C~1000°C. It was indicated that the numerical simulation of was reliable and effective. Moreover, the results would be beneficial to industrialization producing driven spiral bevel gears using precision forging.
Recent development of process simulation for industrial applications
Abstract Manufacturing technologies have advanced over the past decades in many areas. These include process control, manufacturing tolerances, die design, CAD/CAM and process simulation. The constant pressures on manufacturers to reduce cost, minimize lead times and improve quality are ongoing. Automotive, aerospace, energy products, fastener, metals producers and other manufacturing industries are very competitive. Margins are tight even during strong periods of the business cycle. In this paper, the application of process simulation, as applied to the forging, cold heading and heat treatment is discussed. Several applications are presented, with an emphasis on industrial cases.
The “state of the art” in cold forming simulation
Abstract Cold forming technology has advanced over the past two decades in many areas. These include process control, manufacturing tolerances, die design, CAD/CAM and process simulation. The constant pressures on cold formers to reduce cost, minimize lead times and improve quality are ongoing. Automotive, fastener and aerospace manufacturing industries are very competitive and margins are tight even during strong periods of the business cycle. In this paper, the application of process simulation, as applied to the cold forming process is discussed. Industrial examples are presented with an emphasis on die stress analysis.
