  • Entry
  • Associated product(s)
The behavior in relation to tool compensation when changing the tool geometry is dependent on the version of the CNC software.

The behavior is dependent on the version of the CNC software installed:

840D

Wear is deleted upon changing the geometry.


828D / 840D sl

CNC SW 2.6

Wear is deleted upon changing the geometry.

CNC SW 2.7, 4.3, 4.4, 4.5 - 4.5 SP4, 4.7 - 4.7 SP1

Wear is NOT deleted upon changing the geometry.

CNC SW 4.5 SP5 & 4.7 SP2 or later

Wear is deleted upon changing the geometry (default setting). Can be set via SD54215 $SNS_TM_FUNCTION_MASK_SET:
Bit 13 = 0: Wear is deleted upon changing the geometry
Bit 13 = 1: Wear is not deleted upon changing the geometry

Note
If Bit 13 is not visible, activate the checkbox “show all bits”.
