Tool types/tool change with changed dimensions (G40, G41, G42)

Function
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 156 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.
