Study on Solidification Behaviour of LM6 Castings by Using Computer-Aided Simulation Software

摘要

Method layout of a casting is an important aspect of tooling development. It involves decisions regarding part orientation in mould, parting line, cores, cavity layout, feeders, neck and gating system. An improper method layout leads either to poor quality or low yield, which affects the productivity. Method design is mostly carried out manually, using 2D drawing of the cast part Then, tooling fabricates the sample castings, which undergo 3-4 trials, which involves lot of production cost in the farm of wastage of manpower, time and hamper the day-to-day schedule of the particular production. Computer simulation provides a clear insight regarding the location and extent of internal defects, ensuring right casting as first time and every time. In the present study, chunky castings were considered to study the solidification behaviour of LM6 (Aluminium Alloy) at different sizes of riser and riser neck. The VEM-based casting simulation software is used to study the solidification behaviour of above castings. The simulated results were compared with the experimental results. It is expected that this work will be of immense importance equally to the academicians, as well as, to the industrial methoding engineers.
