This function enables the user to generate the nesting result of two identical blanks with common orientation. The Setup and Constraint settings in this function are similar to those described in One-up Nesting. Refer to Section 6.6.1 for a description of commonly used parameters.

The Manual button and Save button are activated after the nesting calculation is completed. This Manual button enables the user to adjust the relative position between two blanks by moving, rotating, and mirroring the blank. Click on the Manual button to open the Manual dialog box illustrated in Figure 6.6.23.

X-Y STEP

This function allows the user to set incremental value in X and Y direction for transformation. The default X-Y step is 10. The setup of parameters is similar to the one in the Constraints page. Refer to Section 6.6.1 for a detailed description.

ANGLE STEP

This is the angle increment for blank rotation. The default angle step is 2 degrees. The setup of parameters is similar to the one in the Constraints page. Refer to Section 6.6.1 for a detailed description.

SELECT BLANK

This function enables the user to select master blank and slave blank respectively, to perform operations such as translation, rotation and mirroring, and adjust the position between blank nestings manually for multiple parts nesting. Once a blank is selected, the outline of this blank turns to grey. Since Master Blank mainly controls the pitch size during nesting, the adjusting button can only be enabled after selecting the Slave Blank option from the list.

The user is also allowed to adjust the blank and cut-off profile directly in the view area. Click on the Position button and the view area is illustrated in Figure 6.6.24. There are green feature points labeled in the center of blank, pitch, width and the side length of cut-off profile. Moving the mouse cursor to the feature point, the program will show the translation and rotation arrows near the cursor for the user to adjust the blank and cut-off profile shape directly. The user can also adjust them through manual adjustment buttons in the Position dialog box. No matter which adjustment method is selected, the current values of the corresponding parameters will be displayed in the position dialog box during adjustment.

When the user selects Two-up Nesting, Two-pair Nesting, Mirror Nesting or Multi blanks Nesting, there are green feature points labeled in the center of the master blank, the center of the slave blank and the center of the two connecting points in the graphic area. The user is allowed to rotate the master blank, the slave blank, or both master and slave together, maintaining their relative orientation, and adjust the positions of the master blank and slave blank.

MANUAL

This function enables the user to manually position the blanks through translation, rotation and mirroring.

TRANSFORMATION

 Move selected blank outline in positive X-Axis direction according to incremental distance.

 Move selected blank outline in negative X-Axis direction according to incremental distance.

 Move selected blank outline in positive Y-Axis direction according to incremental distance.

 Move selected blank outline in negative Y-Axis direction according to incremental distance.

Rotation

 Rotate selected blank outline clockwise by incremental angle.

 Rotate selected blank outline counter-clockwise by incremental angle.

MIRROR

 Mirror the selected blank about Y-Axis.

 Rotate the selected blank 180 degrees about X-Axis, and then mirror it about Y-Axis.

PARAMETERS

this function is used to show the current parameters, and the user may adjust these values directly. According to the adjusted parameters, the program automatically calculates and shows the nesting results, width, pitch and utilization.

L Angle: This option is only available when parallel nesting, isosceles trapezoid nesting, and trapezoid nesting are selected. It is used to show the current angle when adjusting the cut-off profile shape.

R Angle: This option is only available when trapezoid cut-off profile nesting is selected. It is used to show the current angle when adjusting the cut-off profile shape.

Radius: This option is only available when arc nesting is selected. It is used to show the current radius of arc when adjusting the cut-off profile shape.

Angle: Shows the current angle of blank rotation when adjusting the blank position.

Pitch: The program automatically calculates the nesting result, and shows the current pitch of blank on strip according to the adjusted blank position and cut-off profile shape.

Width: The program automatically calculates the nesting result, and shows the current width of blank on strip according to the adjusted blank position and cut-off profile shape.

Utilization: The program automatically calculates the current utilization of blank nesting according to the adjusted blank position and cut-off profile shape.

RECORD

this function enables the user to record the maximum value of utilization calculated from the adjusted nesting results. Besides the maximum utilization, the program will also save the corresponding blank position and cut-off profile shape. Clicking  button, the program will automatically show the nesting result for the maximum utilization in view area and the dialog box.

OK

Click the OK button to confirm the modified nesting result and exit the Manual dialog box.

Cancel

Exit the Manual dialog box without any modification.
