Chapter 8 - Sheet Metal Feature Creation2. Click the Parameters Tab.Set your sheet metal material parameters of:• Stock Thickness - The thickness of the sheet of metal used to manufacture the part.• Minimum Bend Radius - The minimum Bend Radius to be allowed in the model. If youattempt to enter a radius smaller, it will automatically go to this minimum. Default Value =thickness / 2.• Global Bend Radius - The default bend radius used in all instances unless otherwisespecified during feature creation. Default Value = thickness / 2.• K-Factor - During a forming process, "elongation" of the material occurs - a changing ofshape due to the radius pushing material into another location. The "elongation" is calledthe K-Factor, or bend deduction. K-factors can be determined by using material charts.• Global Bend Relief - A small cut made in the material to prevent the bend radius fromcausing a distortion in the metal. Type can be Rectangular (produces a rectangle shapecut) or Round (produces a rectangular cut with a round on the short edge).Default values:Type - rectangularWidth - thicknessDepth - thickness*23.
