Forms
The Forms GCD Type includes one or more Form GCDs, each representing a deformation of metal other than bends. Usually, this is achieved by pressing a shaped punch into the material from one side. The far side can either deflect or not. Depending on their aspect ratios, forms are made by a variety of operations: coining/swaging when the metal thickness is significantly changed, embossing when the deformation depth is relatively shallow, drawing when the metal is significantly stretched, and deep drawing when the metal is extremely stretched. These GCDs are 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
Area (mm2)
The area of the GCD in a flattened state.
 
SER Length (mm)
The length of the smallest enclosing rectangle.
 
SER Width (mm)
The width of the smallest enclosing rectangle.
 
Sub Type
The sub type of the current GCD type. Possibilities include TAB, BRIDGE, EMBOSS, and STAMP.
 
Depth Down (mm)
The depth of the form. This is measured as the maximum distance that any point on the form’s main surface is displaced. It is always a positive number.
 
Depth Up (mm)
The depth of the form. This is measured as the maximum distance that any point on the form’s main surface is displaced. It is always a positive number.
 
Perimeter (mm)
The sum of lengths of all edges in the contour.
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.
