Computer Aided Manufacturing Of Models For Moulding Out Of Synthetic Materials For Producing Sand Casting Moulds

Paper is presenting computer aided machining of models for moulding out of synthetic materials. Goal of the project was to produce a manikin (dummy) from aluminium alloy for testing protective clothes for intervention services. Usage of state-of-the-art software for CAD modeling and CAM machining has been applied. At planning of the machining strategies, the software package UGS NX 7 has been used. Machining of certain models has been done on CNC machining centre Heller BEA 1. Due to dimensional restrictions on the machine workspace we had to part up the models on smaller segments. The model pieces have been made out of synthetic material Sikablock (R) M700. Producing of the models was pretentious and extensive. In project were successfully captured demands for aluminium casting, with these basics we produced objects and produced final casts.
