W1: Tool offset
18.1 Short description
Toolholder with orientation capability
This function permits the machining of inclined surfaces with allowance for tool length compensation, provided
that the kinematics of the toolholder (without NC axes) permits a static orientation of the tool. The more complex
5­Axis transformation is not required for this case.

/FB3/Function Manual, Special Functions; 3- to 5­Axis Transformation (F2)
Appropriate selection of the tool data and toolholder data describes the kinematics for the control such that it can
make allowance for the tool length compensation. The control can take some of the description data direct from
the current frame.
Note
Please refer to the following documentation for further information on tools and tool
compensations and a full technical description of the general and specific programming
features for tool compensation (TLC and TRC):

Flat/Unique D number structure
Compensations can be selected via unique D numbers with management function.
Special handling of tool compensations
The evaluation of signs can be controlled for tool length and wear by the setting data:
SD42900 $SC_MIRROR_TOOL_LENGTH (Sign change tool length when mirroring)
SD42960 $SC_TOOL_TEMP_COMP (Temperature compens. regarding tool).
The same applies to the response of the wear components when mirroring geometry axes or changing the
machining plane via setting data.
