Calling the Tool Table
Before machining starts, select the tool to be used from the tool table.
ND 522/523 then takes into account the stored tool data when
working with tool compensation.
Tool call
Press the TOOL hard key.
Use the UP/DOWN ARROW keys to cursor through
the selection of tools (1-16). Highlight the tool to be
used.
Verify the proper tool has been called, and press the
C key to exit.
Datum Hard 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 522/523's
probing function when probing the workpiece with an edge of a tool.
Datum points can also be set in the 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 eliminate from having to calculate the axis travel when working
with complicated workpiece drawings containing several datums.
