AUTO LOAD CURVE

This function enables the user to calculate the drawbead bending and normal force based on the input of the drawbead geometry and the mechanical properties of blank. As shown in Figure 9.4.9, the user can select the drawbead type and input different parameters.

LIST CURVE

Lists a selected load curve or all load curves in the database.

MODIFY CURVE

Enables the user to edit the load curve data points.

READ CURVE

Allows the user to read an external load curve into the database. Refer to Section 11.11.5 for the format of curve data.

RENUMBER CURVE

Enables the user to edit the load curve identification number of a selected load curve. Refer to Section 11.11.7 for the procedure to renumber load curve.

SHOW CURVE

The user can show a curve by cursor selection at the draw bead or by property name. The rest of the options in this menu are similar to those described in Section 11.11.8.
