The Riser Design System Of Large Steel Castings

With the development of computer hardware and Windows operating system,3D-CAD has been used widely on PC during the latest decade. In the field of castingprocess CAD, the3D software is the inevitable trend in the future, because it is easier torealize the integration of casting process CAD/CAE/CAM. Unigraphics softwaredeveloped by UGS Corporation becomes all-important choice of more and more foundrycompanies for its powerful solid modeling and assembly environment. In the traditionalcasting process design, it demands technologist to master plenty of theory and referring tomany correlative manuals, and it is cockamamie and fallible to design the size of riser.However, riser design is not only the key of casting process, but also very important forCAE simulation. So it is strongly recommended to do some research on it.This riser CAD system is not only a main module of the casting process CADsoftware but also an independently software. It has provided friendly user interface andindependent data operating, and it also shares the same style with UG.In the course of research, the design methods of riser for steel casting have been finedby referring lots of casting process resources, and shrink the range of riser parameters, sothe accuracy of riser design by the methods has been improved markedly. On the otherhand, the riser drawing system improves the efficiency of drawing riser by the parametertechnique and assembly environment in UG. This riser system is easy-to-use relating withpractical production, so it will have a bright application prospect.
