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.
Claims13
A numerical control arrangement, comprising:
- a sheet metal data file defining a part blank, the sheet metal data file having a plurality of position elements associated with machining tasks and having at least one bend defined by a plurality of pre-bends, each pre-bend in the plurality of pre-bends having an associated bend angle that is a portion of a total bend angle of the one bend;
- a machine controller having tool-related operations and control data from said sheet metal data file, the operations associated with machining tasks;
- and
- a machine controlled by said machine controller to form a physical part.
1 more element
A method, comprising:
- receiving a design file for a sheet metal part in a computer;
- recognizing at least one bend by the computer;
- creating, by the computer, a sheet metal data file corresponding to the design file, the sheet metal data file defining the at least one bend by a plurality of pre-bends, each pre-bend in the plurality of pre-bends having an associated bend angle that is a portion of a total bend angle of the one bend;
- and
- storing the sheet metal data file for use by a computed numerically controlled (CNC) machine to create the sheet metal part.
