Application of Non-Destructive Methods to Quality Assessment of Pattern Assembly and Ceramic Mould in the Investment Casting Elements of Aircraft Engines/ Zastosowanie Nieniszczących Metod Do Oceny Jakości Woskowych Zestawów Modelowych Oraz Ceramicznych Form W Procesie Odlewania Precyzyjnego Elementów Silników Lotniczych
The aim of this paper is manufacturing of turbocharger engine jet blades made of nickel superalloys. Processes for producing molds and casting realized in a production line are special processes. It means that the results are known only after inspection of the finished product. There is lack of the methods and techniques of effective and efficient quality control of the work in stock, above all molds. Therefore, the unknown is the state ceramic mold for the precision casting, which resulting in risk of referral to a defective mold of the casting process and thus give the product does not comply, is eliminated in the final inspection.
One method of reducing this risk is particularly thorough monitoring of all parameters of each process and keeping them in the desired operating point. Operating point is a set of parameters of processes. Such monitoring is possible with the commitment to the methods and techniques to automatically, without human intervention, data collection and processing methods appropriate for use in operational control.
The paper presents results of research on the attitude to the problem of a special process. This change is the introduction to the process efficient and effective form of quality control tools in the course of its preparation. In this case, the method of photogrammetry, thermal imaging and computed tomography were used.
With the infrared camera will be possible to determine the temperature field, the disorder in relation to the pattern indicates the type of defect. Computed tomography and will be used to develop patterns of correlated defects associated with thermal imagers. Photogrammetry is the use of a model set of quality control (comparison of the actual state of the model *.CAD). It also allows the designation of a wall thickness of the mold.
