TERMINOLOGY and basis of measurement for curved on plan/bent glass
|a°||Angle||Measured in degrees|
|A||Arc/Girth||Measured in mm|
|T||Thickness of glass|
ANGLE – The angular measurement of a segment of a curved
ARC – The outside length of the curved portion of the bend
(Generally described as either interior arc or exterior arc)
CHORD – A straight-line segment that joins two points of an arc
CONCAVE – The ‘hollow’ face of curved glass
CONVEX – The ‘bulge’ face of curved glass
DEPTH OF BEND – The measurement from the width to the furthest point of curve
GIRTH – The distance around the concave or convex surface measured perpendicular to the rise including any flats.
TEMPLATE – A device manufactured at a scale of 1:1 to determine the shape of the glass bend to be made. (This would be required if none of the above measurements are available.
