Abstract

Methods and systems are disclosed to optimize punching instructions. An example method disclosed herein obtains a tool bed layout, the tool bed including a description of a plurality of tool punch parts, each tool punch part further including tool definition information; obtains a component layout, the component including a description of a component having at least one feature requiring a punching operation; validates the component layout; advances the component to a position of optimum depth; determines a hit score at the position of optimum depth; and repeats the component advancing and the hit score determination until all of the at least one feature of the component is assigned to a tool punch part.

Claims

1. A method of optimizing punching instructions comprising:

obtaining a tool bed layout, the tool bed layout comprising a description of a plurality of tool punch parts, each tool punch part further comprising tool definition information;

obtaining a component layout, the component layout comprising a description of a component having at least one feature requiring a punching operation;

validating the component layout;

advancing the component to a position of optimum depth;

determining a hit score at the position of optimum depth; and

repeating the component advancing and the hit score determination until all of the at least one feature of the component is assigned to a tool punch part.

2. A method as defined in claim 1 wherein advancing the component to a position of optimum depth comprises advancing the component to align a feature thereon proximate to the tool punch part capable of forming the feature.

3. A method of claim 2 wherein aligning the feature proximate to the tool punch part capable of forming the feature includes at least one of aligning the feature directly under the tool punch part and aligning the feature directly under a maximum offset range of the tool punch part.

4. A method as defined in claim 1 wherein determining a hit score comprises evaluating punch capabilities for each of the plurality of tool punch parts at each of the at least one feature of the component.

5. A method as defined in claim 1 further including:

determining positions of optimum depth having a maximum hit score; and

assigning the maximum hit score positions as the optimized punch instructions.

6. A method as defined in claim 1 wherein obtaining the tool bed layout comprises parsing at least one of a formatted file, parsing an XML file, and querying a database.

7. A method as defined in claim 1 wherein obtaining the component layout comprises parsing at least one of a formatted file, parsing an XML file, and querying a database.

8. A method as defined in claim 1 wherein the tool definition information comprises at least one of tool index, tool use count, home location, offset range, dimensions, assignment status, and material type.

9. A method as defined in claim 1 wherein the component layout comprises at least one of component dimensions, component material gauge, number of features, feature type, feature indexes, and feature dimensions.

10. A method as defined in claim 1 wherein validating the component layout comprises determining if at least one of the tool bed layout and the component layout are in a valid format.

11. A method as defined in claim 1 wherein validating the component layout comprises comparing the tool bed layout to the component layout to determine whether the tool bed comprises tools required for punching features of the component layout.

12. A punching instruction optimizing system comprising:
