Application of Computers and Rapid Prototyping Technique as an Element of the Cost-Effective Process of Casting Manufacture
The article describes the advantages that result from the application of computers and rapid prototyping technique. The essence of computer application (simulation of the casting process) consists in acquiring the largest possible volume of information on the run of the technological process, including identification of possible threats. By conventional means and tools, such information and data can be obtAlned in numerous tests, requiring a repeated metal melting operation, which is the most energy-consuming link in the whole casting process. Less frequent melting is possible designing the technological process in a way such that reducing to minimum the uncertAlnty factor and error becomes realistically possible. Due to this it is also possible to reduce the demand for energy consumed in metal melting and emitted during the reverse process. One of the important steps in process studies and design is computer simulation. The second energyconsuming factor in the casting process is the stage of pattern tooling manufacture. Modern systems based on CNC machine tools speed up and shorten the cycle of this manufacturing process. Unfortunately, all these techniques are based on the principle of removing (subtracting) a predetermined amount of the excess material, which in practice means generating heaps of the waste and consumption of large energy volumes. The waste has to be recycled, thus additionally increasing the energy consumption used by the re-processing system. The application of rapid prototyping technique in the fabrication of foundry tooling considerably reduces both the manufacturing cost (due to the reduced level of energy consumption) and the amount of waste produced in the manufacturing cycle, as in this particular case, the manufacturing process consists in additive construction. So, it is a waste-free production and equipment used in this process consumes up to 80％ less energy. Studies on the problems related with reduced energy consumption in casting manufacture have been and are carried out by the Centre of Design and Prototyping operating at Foundry Research Institute in Krakow.
