First Claim
1. A method performed by a computer system having a non-transitory, machine-readable memory and a processor for creating control values for controlling a computer numeric control (CNC) cutting device to cut a flat fiberboard sheet for configuration as a three-dimensional, engineered, shaped building panel, the method comprising:
- receiving within the computer system a first input of a plurality of structural properties of the flat fiberboard sheet-as a first set of variable values;
receiving within the computer system a second input of a plurality of physical and geometric properties of the three-dimensional engineered shaped building panel configuration as a second set of variable values;
storing the first set of variable values and the second set of variable values in the memory;
calculating with the processor structural and performance properties of the three-dimensional, engineered, shaped panel using a set of equations that incorporate a plurality of variable values from the first set of variable values and the second set of variable values;
calculating with the processor respective positions, widths, depths, and lengths for both a first cut on a top surface of the flat fiberboard sheet that extends to a first depth short of a bottom surface of the flat fiberboard sheet and a second cut on the bottom surface of the flat fiberboard sheet parallel to and spaced apart at a predetermined distance from the first cut that extends to a second depth short of the top surface of the flat fiberboard sheet using a set of equations that incorporate one or more variable values from the second set of variable values, wherein the positions of the first and second cuts are calculated to form a single hinged fold joint along the flat fiberboard sheet that fits the calculated structural and performance properties required to form the three-dimensional, engineered, shaped building panel configuration;
generating with the processor a set of control values corresponding to the respective positions, widths, depths, and lengths of the first cut and the second cut in a format configured to provide control instructions to the CNC cutting device; and
outputting the set of control values.

Abstract
A three-dimensional engineered shaped fiber configuration is formed using determined structural requirements for a three-dimensional engineered shaped fiber configuration and ascertained properties of an engineered molded fiber fiberboard material. A first cut on a top surface and a second cut on a bottom surface of the fiberboard material are calculated. These calculations are based, at least in part, on the structural requirements properties of the fiberboard material. The first cut and the second cut each have a depth, a width, and a position. The first cut and the second cut have a spacing between them such that the flat piece of fiberboard material can be folded at a point located in the spacing between the first cut and second cut to position a first portion of the fiberboard material at a particular angle with respect to a second portion of the fiberboard material.
