Workpiece Alignment

To Define the Cut Position:
1 Use the X/Y-Axis Controls to move the Camera to the reference point.
2 Click Finish. The System automatically calculates and displays the
cut map for that angle in the Main Workspace Window in the Video
Workspace, according to the recipe parameters.
When the User has completed the two steps that comprise Manual
Alignment, the entire procedure is repeated for the other angles defined in
the Recipe for that Workpiece. For instance, if Angles 0º and 90º have been
defined, Manual Alignment is first performed at 0º then at 90º. Switch
between the two angles by changing the Theta using the Z/T Axis Controls
(selecting
then or ).
6.1.2 Auto Alignment
During normal operation, the Model 7100 uses Auto Alignment when
processing a large number of identical Workpieces. In order to use Auto
Alignment, the following two procedures must first be performed:
• Teach Index (obligatory for "Street" alignment type only)
• Teach Alignment
Note: For APC algorithm the defined cut position is normally the point where
the blade enters the Workpiece. For GPC algorithm, the defined cut position is
anywhere in a center of a street. The cut map is displayed according to the cut
position referred to the chuck center.
