Modifications during rotation of milling and tapping tools

The cutting edge position is recalculated appropriately during a rotation of a milling or tapping
tool. Cut direction and tool angle (clearance angle or holder angle) are not defined for milling
and tapping tools so that the change in cutting edge position is derived exclusively from the
rotation. Thus, for milling and tapping tools, the cutting edge position always changes when the
amount of rotation with reference to the zero setting is more than 45°.

Response in the event of an error
Different fault conditions can occur during the activation of the function "Modification of the
offset data for rotatable tools" (by an explicit call in the part program or by tool selection). For
errors with error numbers < 100 (see Diagnostics Manual), it is possible to define whether the
error will trigger output of an alarm and, if so, whether such an alarm will only be displayed or
will also trigger program stop. The setting is made in the following machine data:
MD20125 $MC_CUTMOD_ERR
150
