Abstract

A numerical control arrangement, comprising a sheet metal data file defining a part blank having a plurality of position elements from a processed design file; a machine controller comprising tool-related operations and control data from said sheet metal data file defining a plurality of position elements, the operations and position elements being associated with machining tasks; and a machine controlled by said machine controller to form a sheet metal part and appropriate means and computer-readable instructions.

Claims

1. A numerical control arrangement, comprising:

a sheet metal data file defining a part blank having a plurality of position elements from a processed design file;

a machine controller having tool-related operations and control data from said sheet metal data file defining a plurality of position elements, the operations and position elements being associated with machining tasks; and

a machine controlled by said machine controller to form a physical part.

2. The numerical control arrangement of claim 1, wherein said sheet metal data file has a plurality of calculated bend parameters corresponding to a plurality of identified linear bends.

3. The numerical control arrangement of claim 2, wherein said calculated bend parameters includes one of a bend angle, an inside bend radius, and a part thickness.

4. The numerical control arrangement of claim 2, wherein said calculated bend parameters include an over-bend as necessary.

5. The numerical control arrangement of claim 1, wherein the numerical control arrangement provides numerical control of a machine tool and a robot.
