W artykule zostały przedstawione techniki powstawania prototypowych odlewów z zastosowaniem połączenia technologii odlewniczych z technikami szybkiego prototypowania. Pokazano kolejne etapy procesów wykonywania odlewów gazo-hamulca, części uchwytu kierownicy, odbojnika pojazdu gąsienicowego, elementu stawu kolanowego.

The techniques of the creation of prototype castings using a combination of casting technologies and rapid prototyping techiques are presented in the paper. The successive stage of he gas-brake part, steering handle, tracked vehicle and knee joint casting process are shown.

This paper deals with production of safety inlay for steam locomotive valve by the Patternless Process method. For the moulds creation was used moulding mixtures of II. generation, whereas binder was used a water glass. CNC miller was used for creation of mould cavity. Core was created also by milling into block made of moulding compound. In this article will be presented also making of 3D model, setting of milling tool paths and parameters for milling.

Device for production of prototype moulds by milling

This paper deals with a new mode of production of prototype castings by the method of Patternless Process and a device for production of moulds used in the method of patternless process. The principle of the Patternless Process method consists in creating a 3D model in the CAD system and subsequent milling to form a casting from the block of moulding sands without using of pattern equipment by using a CNC machine tool. This method markedly reduces the time needed to produce the casting, because this method does not need the production of pattern. The paper deals with selecting a machine for production of prototype castings by Patternless Proccess and a detailed description of a device to be used for making moulds. The paper describes in detail the design of the device and individual components needed in the construction of the machine.
