Brief 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 more information about 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
Setting data
SD42900 $SC_MIRROR_TOOL_LENGTH
to
SD42960 $SC_TOOL_TEMP_COMP
can be used to control the evaluation of the signs for tool length and wear.
The same applies to the response of the wear components when mirroring geometry axes or
changing the machining plane via setting data.

– Collision detection selectable:
Possible contour violations are detected predictively, if:
- Path is shorter than tool radius
- Width of an inside corner is shorter than the tool diameter
– Keep tool radius compensation constant
– Intersection procedure for polynomials
