NX-based Development of Mold Interference Checking Software

An auto mold interference checking software in which cast processing properties were taken into consideration was developed based on the application development of Unigraphics NX 3D design platform. During auto mold structure design, casts, such as punch , blank holder and so on, need to add margin on specific surfaces during casting process because of cast deviation, then numerical control is used to process these surfaces. In checking the interference of all the mold assembly structures, this software can comprehensively considerate the clearance between cast and cast, cast and NC process surface, NC process surface and NC process surface. At last a mold example is used to show the interference checking.
