Casting process optimization by the regression analysis applied on the wear resistant parts moldingSlavković, Radomir (Avtor) Arsovski, Slavko (Avtor) Veg, Aleksandar (Avtor) Jugović, Zvonimir (Avtor) Jovićić, Aleksandar (Avtor) Dučić, Nedeljko (Avtor) castingmathematical modelquality managementwear resistanceConducting a comprehensive research of the casting process of wear resistant parts (white hard casting), a significant correlation is established between the technological parameters (temperature, aging time in the mold and coolant flow) and the final product hardness. The fundamental theory of Box-Wilson's gradient method marked the baseline for the foreseen researches. The method defines the coherence of the process parameters, since their dispersion in the examined process is relatively small. Main target of the experiment was a definition of the optimal casting conditions. Therefore the different technological routes are identified and the casting process is modified until the best outcome is achieved. Target function was initially in a hypothesized form, while later on evolved into a consistent form due to the application of experiment-statistics, process optimization and process management based on empirical feedback.20122017-07-11 11:56:40Znanstveno delo66802ISSN: 1330-3651UDK: 621.941:004.89OceCobissID: 15346181COBISS_ID: 18034966ISSN pri članku: 1330-3651NUK URN: URN:SI:UM:DK:PYNWZMPQsl
