Simulation of the Stir Casting Process
Non homogeneous particle distribution is one of the greatest problems in casting Metal Matrix Composites (MMC's). To optimize some of the parameters for uniform particle distribution for batch compocasting the present simulation studies were conducted. The simulation involves visualisation experiments. In the visualisation experiments liquid and semi solid aluminium are replaced by other fluids...
متن کاملOptimization of the Investment Casting Process
Rapid prototyping is an important technique for manufacturing. This work refers to the manufacture of hollow patterns made of polymeric materials by rapid prototyping technologies for its use in the preparation of ceramic molds in the investment casting process. This work is focused on the development of a process for manufacturing patterns diff erent from those that currently exist due to its ...
متن کاملNumerical Simulation of the Investment Casting Process
Determining alloy shrinkage factors is very important for the investment casting process. Casting dimensions can be obtained from numerical simulations of heat transfer and deformation phenomena. The accuracy of the dimensional results depends on heat transfer results. In order to validate heat transfer models, temperature data were obtained during casting of aluminum alloy A356 in shell molds ...
متن کاملReliability-based Casting Process Design Optimization
Optimum casting designs are unreliable without consideration of the statistical and physical uncertainties in the casting process. In the present research, casting simulation is integrated with a general purpose reliability-based design optimization (RBDO) software tool previously developed at the University of Iowa. The RBDO methodology considers uncertainties in both the input variables as we...
متن کاملCasting Process Planning Using Case Based Reasoning
We present an innovative approach to casting process planning based on case-based reasoning. Process planning involves deciding the methods, materials and machines for various steps in manufacturing. It is an important activity that affects product cost and quality, and requires experience. Such experience can be stored using a knowledge management system, then retrieved and modified for a new ...
