This paper looks at a current method of generating geometric forging models for jet engine components, specifically jet engine disks and aims to find geometric models that require less information and retain the existing model’s level of accuracy. In order to create models that require less information Attribute Estimating Relationships (AERs) are generated to estimate attribute dimensions, these estimated attribute dimensions are used to generate the forging model of the disk. AERs are generated using two different methods the Standard Deviation (SD) method and the Sum of Squares (SS) method. These two methods are analyzed and the SS method is determined to be superior in this case. Using the SS method to generate AERs it is possible to develop a geometric forging model that requires less information and also retains a high level of accuracy.
