Abstract
Computer implemented method for making a die includes: selecting coating uniformity required to produce a particular coated product with the die and a value for one or more dimensions of the die; determining (using a mathematical model determined by regression analysis) total indicated run-out (TIR) of a die surface and dimensions of the die not having a user specified value; and machining die part or parts to the determined TIR and dimensions. A thermal treatment process for reducing the number of finishing (e.g., grinding) cycles needed to produce a desired die flatness is provided. A coating fluid rheological characteristic can be an input to the method.
