Bends

The Bends GCD Type includes one or more StraightBend GCDs, which represent only co-axial cylinders having the same radius. These GCDs are available for the Sheet Metal and Bar and Tube process groups. 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	Bend Angle (deg)	The total angle that the bend passes through. Unbent, this angle equals 0. A hem equals 180 degrees.
	Clock Angle (deg)	Angle measured in a plane perpendicular to the tube/bar axis
	Bend Direction	Indicates the direction of the bend with respect to the main surface. Possible values include UP, DOWN, BOTH, EITHER, and UNKOWN.
	Bar Position, From (mm)	Distance from the bar origin to the start of the bend GCD.
	Bar Position, To (mm)	Distance from the bar origin to the end of the bend GCD.
	Length (mm)	The length of the GCD.
	Min Bend Radius (mm)	The minimum radius of any bend surface along the chain measured from the bend interior.
	Neutral Bend Radius	Radius of bend measured to the neutral axis.
	Bend Flap Size	The maximum distance between two neighboring bends or a bend and a neighboring blank contour.
	Is Straight	Indicates whether the bend goes along a line axis. If true, the bend is straight.
	Is Gusset	Indicates whether the bend has a gusset (a special type of emboss) put across the bend as a strengthener.
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.
