Mill shapes, tool data
The table below gives an overview of the tool shapes
which may be used in face milling operations as well
as tool data limit values.
The shape of the tool shaft is not taken into
consideration – the tools 120 and 155 are identical in
their effect.
If a different type number is used in the NC program
than the one listed in the table, the system
automatically uses tool type 110 die-sinking cutter.
An alarm is output if the tool data limit values are
violated.

compensation (intersection longitudinal
