Online tool length offset

Functionality
Effective tool length can be changed in real time so that the length changes are also considered
for changes in orientation of the tool. The system variable $AA_TOFF[<geometry axis name>]
includes tool length compensations in 3-D according to the three tool directions.
None of the tool parameters are changed. The actual compensation is performed internally by
means of transformations using an orientable tool length compensation.
The number of active compensation directions must be the same as the number of active
geometry axes. All offsets can be active at the same time.

Comment
; orientation transformation active.
; interpolate tool orientation as vector
; select large circle interpolation.
; orientation in the Y/Z plane by 45
; degrees rotated, at the block end the
; orientation (0, 1 / (root of 2),
; 1 / (root of 2) is reached.
; the orientation vector is interpolated on a
; conical surface with direction
; (1 / (root of 2), 0, 1 / (root of 2)
; in the clockwise direction,
; the angle of rotation is 270 degrees.
; The tool orientation traverses a complete
; rotation on the same peripheral surface of the
cone
