Abstract :
Develops a model that identifies changes in process control parameter values by analysing the geometry of a product from a forging process. That is, shape variations from the norm of a forged part are linked to the variations of the process parameters of the forging process. This is an important aspect of inspection analysis because it implies that the analysis of shape variation can return the potential errors within the product and also the changes needed to the process control parameters to correct errors in the product shape. Our model can identify whether input parameters of interest are too high or too low to an accuracy of at least 70%. Given the complexity of the forging process these initial results show promise
