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.

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.
