Identification of the Composite Surfaces with the Application to the Casting and Deep Drawing Dies

Résumé

This article proposes a new method for the generation of concave casting surfaces of the dies for the casting parts, which in most of the cases, are very complex. This proposed method is designed to improve the accuracy of the casting dies manufacturing in order to avoid future corrections. Generation of the die surface is based on a polynomial equation having two variables – x, y. For each known values of x and y we will obtain z coordinate of each point on the concave die surface.
