Process for optimizing a core die

Abstract

A process for optimizing a core die is provided. By iteratively modifying the ceramic core without changing the core die, it is possible to ascertain an optimum core without modifying the core die every time. In a last step, an optimum core die is produced using the optimum ceramic core.

1 - 4 . (canceled) 
     
     
         5 . A process for producing a new core die for a ceramic casting core, comprising:
 producing a ceramic core using an initial core die;   carrying out a casting process using the ceramic core, and   carrying out specification measurements on an obtained cast component,   wherein when the cast component deviates from its desired values, the initial core die is not modified, but instead the ceramic core is in turn produced using the same initial core die and the ceramic core is processed to form a modified core,   wherein the modified core is used for casting until the modification of the ceramic core or the modified core have the effect that the cast component complies with the required specifications, and   wherein the new core die is then produced using the modified core.   
     
     
         6 . The process as claimed in  claim 5 , wherein elevations are produced as the modification or are modified. 
     
     
         7 . The process as claimed in  claim 5 , wherein the modification is distributed only in a partial region of the modified core. 
     
     
         8 . The process as claimed in  claim 5 , wherein a rate of flow through an interior of the cast component is determined in order to determine a deviation from the specification.
