Abstract:
1. A control module that controls a draw die process comprising: a press parameter database stored in memory that contains a plurality of press parameter combinations corresponding to a plurality of different mechanical properties of materials, wherein each one of the plurality of different mechanical properties has at least one press parameter combination corresponding thereto, and wherein each specific press parameter combination of the plurality of press parameter combinations has associated therewith a probability of one of a successful draw die process and a failed draw die process given the specific press parameter combination and the one of the different mechanical properties corresponding to the specific press parameter combination; a parameter determination module that receives mechanical properties corresponding to a plurality of blanks that are to undergo the draw die process, retrieves a press parameter combination based on the received mechanical properties and a probability associated with the retrieved press parameter combination, the probability being indicative of a likelihood of one of a successful draw die process and a failed draw die process given the retrieved press parameter combination and the received mechanical properties, and provides the retrieved press parameter combination to a draw die system that performs a first draw die process on a first blank from the plurality of blanks; and a feedback module that receives a result of the first draw die process, determines whether the first draw die process resulted in failure or in success, and adjusts the probability associated with the retrieved press parameter combination based on whether the first draw die process resulted in failure or in success.
