Analysis of Casting Defects using Casting Simulation Technique and Using Design of Experiment: A Review
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Computer simulation of casting process has emerged as a powerful tool for achieving quality assurance without time consuming trials. Software packages for simulating the solidification of molten metal in the mould enable predicting the location of shrinkage defects and optimizing the design of feeders to improve the yield; more advanced packages perform coupled simulation of mould filling and casting solidification. Simulation is the process of imitating a real phenomenon using a set of mathematical equations implemented in a computer program. In Casting simulation the mould filling and solidification analysis is done by using an algorithm or program based on finite volume method, to identify the hot spots and hence defects like shrinkage, hot tears, cracks, etc. [4]. In casting processes, there are various parameters which works at different levels may influence the casting defects. For each type of defect, several causes have been listed under differing categories such as design, moulding and pouring/melting related parameters. The literature review indicates that Taguchi Method is the best option for Design of Experiments. This paper reviews the various literatures on the casting simulation technique and DOE for casting defects analysis.
