ORNT - Tool Orientation (Tool Geometry Data Table)
The control uses the value entered here to determine the orientation of the
tool’s cutting edge relative to the surface of the part. This is necessary for
the control to perform TTRC correctly. Refer to chapter 21.

The control uses the value entered here to determine the orientation of the
tool when Tool Tip Radius Compensation is active. Each tools’orientation
should be determined from Figure 3.5 and Figure 3.6 and its number
entered (0-9) on the geometry offset table for the ORNT parameters. From
that information the control can keep track of the orientation of the tool
currently being used and help catch some programming errors.
