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.
