Abstract Details

2010, Master of Science, Ohio State University, Mechanical Engineering.
The estimation of forging die wear and cost are both important issues. Die wear accounts for a large portion (almost 70%) of die failures. This leads to increased costs to replace the die, through downtime and the cost of the die itself. Through finite element method (FEM), forging processes can be simulated and the die wear can be predicted. This allows for optimization of the forging process and increase in die life, as well as reduction in die try-out time and a proactive replacement of dies, which helps reduce scrap and downtime. Through two case studies of elevated temperature extrusion, it is shown that wear and plastic deformation prediction is possible. With these predictions, the extrusion processes can be improved for better die life and part quality in the future. Accurate die cost estimation helps with early stage quoting processes. If a forger or purchaser is able to get an idea of the die costs, then it makes the whole procedure a little less of a guess. However, accurate quotes require a large amount of information. Thus, if it is possible to relate final part geometry to die cost, then a good estimate can be achieved almost immediately. The procedure to estimate cost has been outlined and the initial steps have been started.
