Common Parameters of Sheet Metal Commands > K-Factor

The parameter allows specifying the neutral layer coefficient. The parameter controls K-factor definition upon part bending and unbending. The parameter is required for all operations that have an unfolding. The neutral layer of a workpiece is its longitudinal section, whose geometry does not change during bending.

1 - Workpiece; 2 - Workpiece thickness; 3 - Neutral layer; 4 - Bend radius; 5 - Bend angle; 6 - Bent workpiece

The neutral layer coefficient value can either be entered by the user or defined by the system automatically, based on the table of The way of setting is determined by the drop-down list. To automatically determine the neutral layer coefficient, select the option From Table. Another option will allow you to set an arbitrary numeric value between 0 and 1. The value “0” means the neutral layer coincides with the workpiece face selected for bending, while “1” sets the neutral layer on the opposite face of the workpiece.

The K-factor dependency table is stored with the model document. You can view and change the table in the default parameters dialog for sheet metal.
