Calling the Tool Table

Before you start machining, select the tool you are using from the tool
table. ND 780 then takes into account the stored tool data when you
work with tool compensation.

Tool call

Press the TOOL soft key.
TOOL NUMBER
Use the UP/DOWN ARROW keys to cursor through
the selection of tools (1-16). Highlight the tool you
want.
Verify the proper tool has been called, and press the
C key to exit.

Datum Soft Key

Datum settings define the relationships between the axis positions
and the display values.
The easiest way to set datum points is to use the ND 780's probing
functions – regardless of whether you probe the workpiece with an
edge finder or a tool.
Of course, you can also set datum points in the conventional manner
by touching the edges of the workpiece, one after the other with a tool
and manually entering the tool positions as datum points (see
examples following this page).
The datum table can hold up to 10 datum points. In most cases this
will free you from having to calculate the axis travel when working
with complicated workpiece drawings containing several datums.
