Blank
The Blank GCD Type includes a single GCD named Blank, which represents the flattened sheet metal part after the external contour is cut. This GCD is available for the Sheet Metal process group. The GCD details include:
 
Cost drivers
Description
GCD
Name
The name and number that identifies the GCD. This information is an identifier only and is not used in any cost calculation.
Properties
Perimeter (mm)
The sum of lengths of all edges in the contour.
 
SER Length (mm)
The length of the smallest enclosing rectangle. This value can be edited by you if aPriori determines an incorrect blank size.
 
SER Width (mm)
The width of the smallest enclosing rectangle. This value can be edited by you if aPriori determines an incorrect blank size.
 
Thickness (mm)
The thickness or gauge of the sheet metal blank or part (mm). This value is extracted from the CAD model.
 
Chamfer Direction
Indicates the direction of the chamfer with respect to the main surface.
 
Curved Length (mm)
The sum of lengths of non-straight edges in the contour.
 
Is Chamfered
Indicates if the edges of the GCD are chamfered. If true, the edges are chamfered.
 
Max Radius (mm)
The maximum radius of the curvature for non-straight edges of the contour. The value equals 0 if all edges are straight.
 
Min Radius (mm)
The minimum radius of curvature for non-straight edges of the contour.
 
Number of Coining Chains
The number of contiguous chains of coined edges.
 
Num Curved Edges
The number of non-straight edges in the contour.
 
Num Edges
The number of edges in the contour.
 
Straight Length (mm)
The total length of the straight edges on the perimeter of the part.
 
Worst Peninsular Ratio
The maximum (Peninsula Length/Peninsula Width) for all peninsula on a contour. Peninsula are the outstanding tabs on a contour of blank or complex hole.
 
Worst Peninsular Ratio2
The maximum (Peninsula Length/Peninsula Width2) in 1/mm. Peninsula are the outstanding tabs on a contour of blank or complex hole.
Technique
Requested
The technique selected by you. If you have not selected a technique, this field is set to auto-select.
 
Selected
The technique used by aPriori. If the requested technique cannot be used, aPriori will select a technique that can be used.
Results
Status
The costing status of the GCD or technique. A green icon indicates that costing was successful, a yellow icon indicates that costing succeeded with a warning, and a red icon indicates that costing failed.
