Once you set the Tool Path Graphics parameters for your particular solution, select [OK] or
[ENTER] to save your changes and to exit this window. The system notifies you of any
parameters that are set incorrectly. To exit this window without saving your changes, select
[CANCEL] or [ESC]. The previously saved parameters remain valid.
The following sections provide details about Tool Path Graphics parameters.
Sample Rate
The CNC uses this parameter to update the axis position data for Tool Path Graphics. The
sample rate (measured in fine scan time increments) ranges from 2 to 65,535 ms.
Process 1/Process 2
This indicates the number of the visualized process. This parameter is always set to “Process
1” unless you operate a dual-process system.
Inch/Metric
These buttons allow you to select the units used by the Tool Path Graphics configuration
parameters.
Horizontal axis name
This is the name of the axis that represents the abscissa.
Vertical axis name
This is the name of the axis that represents the ordinate.
IMPORTANT
If the rate you use is not an exact multiple of the fine scan time, the utility
automatically rounds up or down to the nearest incremental multiple of
the sample frequency.
TIP
For a more detailed image, we recommend using a
relatively low sample rate. The lower the sample rate, the
greater the number of points the system retrieves. The
system saves the last 16384 points. In the event that your
plot exceeds this limit, the latest points override the older
points.
