Praca dotyczy procesu budowy zrobotyzowanego stanowiska do mycia, suszenia i sprawdzania szczelności form odlewniczych aparatów kierujących lotniczej turbiny niskiego ciśnienia. Proces przygotowania precyzyjnych wielowarstwowych ceramicznych form odlewniczych jest etapem żmudnym i czasochłonnym. Formy ceramiczne dotychczas czyszczono i myto w sposób ręczny i odkładano do magazynu w celu samoistnego wysuszenia. Przeprowadzono robotyzację tych dwóch podstawowych procesów oraz dodano etap sprawdzania szczelności form. Na poszczególne podzespoły i stację zrobotyzowanego zgłoszono wynalazki do Urzędu Patentowego a zaprojektowaną i zbudowaną stację wdrożono w firmie CPP (Consolodated Precision Products Poland sp. z. o.o.).

The work concerns the process of building a robotic stand for washing, drying and checking the tightness of casting molds of the steering apparatus of a low pressure aviation turbine. The process of preparing precise multilayer ceramic casting molds is a tedious and time consuming stage. Until now, ceramic molds have been cleaned and washed manually and placed in a warehouse for self drying. Robotization of these two basic proceeded was carried out and the stage of checking the tightness of the molds was added. The inventions were submitted to the Patent Office for individual components and the robotic station, and the designed and built station was implemented at CPP (Consolodated Precision Products Poland sp. z. o.o.).

During excavation of the cremation cemetery of urnfield culture in Legnica at Spokojna Street (Lower Silesia, Poland), dated to 1100-700 BC, the largest - so far in Poland – a collection of casting moulds from the Bronze Age was discovered: three moulds for axes casting made out of stone and five moulds for casting sickles, razors, spearhead and chisels, made out of clay. This archaeological find constituted fittings of foundrymen’s graves. In order to perform the complete analysis of moulds in respect of their application in the Bronze Age casting technology analytical methods, as well as, computer aided methods of technological processes were used. Macroscopic investigations were performed and the X-ray fluorescence spectrometry method was used to analyse the chemical composition and metal elements content in mould cavities. Moulds were subjected to three-dimensional scanning and due to the reverse engineering the geometry of castings produced in these moulds were obtained. The gathered data was used to perform design and research works by means of the MAGMA5 software. Various variants of the pouring process and alloys solidification in these archaeological moulds were simulated. The obtained results were utilised in the interpretation of the Bronze Age casting production in stone and clay moulds, with regard to their quality and possibility of casting defects occurrence being the result of these moulds construction. The reverse engineering, modelling and computer simulation allowed the analysis of moulds and castings. Investigations of casting moulds together with their digitalisation and reconstruction of casting technology, confirm the high advancement degree of production processes in the Bronze Age.

The article deals with the effect on the quality of casting moulds (metal, bentonite mixture) on the structure of the alloy AlZn5,5MgCu and selected mechanical properties of the alloy. The effect of foundry moulds can significantly affect formation and range of crystal segregation and the subsequent thermal process of homogenization which has an influence on the final quality of the alloy. The research focuses on the formation and range of crystal segregation and its removal with homogenization annealing, in which the observed influence of individual factors influencing the diffusion process and quality of the aluminium alloy.
