Effect of Technological Parameters on the Quality and Dimensional Accuracy of Castings Manufactured by Patternless Process Technology

Abstract

Submitted article deals with the effect of selected technological parameters on the quality and dimensional accuracy of prototype castings made by Patternless process technology. During experiments were used two types of molding compounds (foamed gypsum and compound based on silica sand and resin). Experiments were focused on optimization of cutting parameters in terms of efficiency, accuracy and possibilities to minimize tool wear. Article deals also with the dimensional and shape accuracy of the castings made by Z-Cast technology. The main aim of the research is to optimize Patternless process technology to such an extent, that achieved dimensional and shape accuracy will be comparable to castings made by the Z-Cast technology.Keywords: silica sand, patternless process, cutting parameters, gypsumArtykuł dotyczy wybranych parametrów technologicznych, które wpływają na jakość i dokładność wymiarową odlewów prototypowych wykonanych technologią bezmodelową. Podczas eksperymentów wykorzystano dwa rodzaje form (spienionego gipsu i mas do formowania na bazie piasku kwarcowego i żywicy). Badania mają na celu optymalizację parametrów cięcia w zakresie wydajności, dokładności i zminimalizowania zużycia narzędzi. Artykuł zajmuje się również dokładnością wymiarów i kształtem odlewów wytwarzanych za pomocą Z-cast. Głównym celem tego badania jest bezmodelowa technika optymalizacji tworzenia do takiego stopnia, aby osiągnąć dokładność wymiarów i kształtu odlewu wytworzonego zpomocą Z-cast.

“…Reparable defects are deviations where by using a well suitable repair procedure (flattening, annealing, welding) that is according to the specification. [13][14][15] However, there are some factors that influence the results of the ultrasonic testing method. Among the device and the probe most significant are acoustic binding, tested surface, tested material, shape of the component and the properties of the defect.…”

Identifying the cause of cutting tool failure by using simulation software

“…At different heights the cutting force is not so high and the dynamic strain on the machine and tool is lower. Cutting energy (integrated area under the cutting force curve) is for cutting with the identical height of the punches theoretically equal to the total of cutting energy for classes of punchers with the same height [8,10,11].…”
