Minimizing the Sand Casting Defects Using Taguchi Method
Abstract: The global market is becoming more and more quality conscious now a days. This Research work includes minimization of sand casting defects in C.I. based foundry. The survey was carried in small scale CI based foundry (Surat). Major defects were observed are misrun, coldshut, blowholes, and porosity. Taguchi method is used to optimize the control parameters like moisture, permeability, pouring time, pouring temperature. L18 orthogonal array is used in this …

Optimization of Green Sand Casting Process Parameters by Artificial Neural Network
Abstract: In this paper, artificial neural network (ANN) is used to train the network which can predict the casting defect. L27 orthogonal array is used as input matrix for training of neural network. NN tool is used to train the network for prediction of defects. Major defects observed on shop floor were; misrun, blowholes, inclusions and porosity. Moisture, permeability, LOI, compressive strength, volatile content, vent holes, pouring time, pouring temperature, mould …
