Radial growth is the phenomenon where the bend radii increase during bending. For example, the bend die may be machined at a 1-inch centerline radius, but the tube radius after bending expands to 1.050 inches.
VTube-LASER Can Measure Bend Radii
VTube-LASER can measure the actual radius using the Bend Profile measure process. See this page for more information.
