Process-level Feasibility
Process feasibility depends on the values you supply for the geometric PSOs. Turret Press is feasible only if all the following hold:
• You have supplied values for all required PSOs.
• You have supplied nonzero values for all the following PSOs:
o Part Volume
o Width of the flat pattern’s Smallest Enclosing Rectangle
o Length of the flat pattern’s Smallest Enclosing Rectangle
o Thickness of the flat pattern’s Smallest Enclosing Rectangle
• Length of the flat pattern’s SER is greater than or equal to Width of the flat pattern’s SER.
• If your routing includes surface treatment, you have supplied a non-zero value for the PSO Surface Area of the Part.
• If your routing includes surface treatment or other secondary processes, you have supplied nonzero values for all the following PSOs:
o Length of the finished part’s Bounding Box
o Width of the finished part’s Bounding Box
o Height of the finished part’s Bounding Box
• If your routing includes surface treatment or other secondary processes, both the following hold:
o Height of finished part’s Bounding Box is less than or equal to Width of finished part’s Bounding Box
o Width of finished part’s Bounding Box is less than or equal to Length of finished part’s Bounding Box.
• For each conditionally required PSO, you have supplied a nonzero value if and only if you have supplied a nonzero value for its associated PSO. For example, you have supplied a nonzero value for total bend length if and only if you have supplied a nonzero value for number of bends.
• If you supplied a value greater than 0 for Number of Small Rounded Sections, you supplied an equal or smaller value for Unique Radii in Number of Small Rounded Sections.
• If you supplied a value greater than 0 for Number of Small Round Holes, you supplied an equal or smaller value for Unique Radii in Number of Small Round Holes.
• If you supplied a value greater than 0 for Number of Holes made with Cluster Punches, then Number of Holes made with Cluster Punches divided by Number of Unique Cluster Punches is greater than or equal to Average Number of pins per Cluster Punch tool (9 by default).
• If you supplied a value greater than 0 for Number of Forms, you supplied an equal or smaller value for Number of Unique Forms.
• If you supplied a value greater than 0 for Number of Flanged Holes, you supplied an equal or smaller value for Number of uniquely shaped Flanged Holes.
• If you supplied a value greater than 0 for Number of Countersunk Holes, you supplied an equal or smaller value for Unique Sized in Number of Countersunk Holes.
• If you supplied a value greater than 0 for Number of Tapped Holes, you supplied an equal or smaller value for Unique Sized in Number of Tapped Holes.

Bend Brake Feasibility
Bend Brake is included in a routing only if one of the following holds:
• Part has hemmed bends (PSO Number of Hemmed Bends is greater than 0).
• Part has bends (PSO Number of Bends is greater than 0)
Bend Brake is feasible only if both the following hold:
• Maximum Bend Radius >= Minimum Bend Radius.
• Either part has hemmed bends or part’s minimum bend radius is not too small.
Minimum bend radius is considered too small if and only if PSO Minimum Bend Radius is greater than or equal to the product of PSO Thickness of Part and cost model variable minBendRadiusRatio (0.5 in aPriori basleines).
