Chapter 8 - Sheet Metal Feature Creation and Part Parameters2. Click the Parameters Tab.Set your sheet metal material parameters of:• Stock Thickness - The thickness of the sheet of metal used to manufacturethe part.• Minimum Bend Radius - The minimum Bend Radius to be allowed in themodel. If you attempt to enter a radius smaller, it will automatically go to thisminimum. Default Value = thickness / 2.• Global Bend Radius - The default bend radius used in all instances unlessotherwise specified during feature creation. Default Value = thickness / 2.• K-Factor - During a forming process, "elongation" of the material occurs - achanging of shape due to the radius pushing material into another location.The "elongation" is called the K-Factor, or bend deduction. K-factors can bedetermined by using material charts.• Global Bend Relief - A small cut made in the material to prevent the bendradius from causing a distortion in the metal. Type can be Rectangular(produces a rectangle shape cut) or Round (produces a rectangular cut with around on the short edge).• Default values:• Type - rectangular• Width - thickness• Depth - thickness*2208
