M1: Kinematics transformation
2.3 Oblique angle transformation (inclined axis) TRAANG (option)
Selection and deselection
● An intermediate motion block is not inserted (phases/radii).
● A spline block sequence must be terminated.
● Tool radius compensation must be deselected.
● The current frame is deselected by the control system. Corresponds to programmed G500.
● An active working area limitation is deselected by the control for the axes affected by the
transformation (corresponds to programmed WALIMOF).
● An activated tool length compensation is included in the transformation by the control.
● Continuous path control and rounding are interrupted.
● DRF offsets must have been deleted by the operator.
● All axes specified in machine data MD24110 $MC_TRAFO_AXES_IN_n must be
synchronized on a block-related basis (e.g. no traversing instruction with POSA...).
Tool change
Tools may only be changed when the tool radius compensation function is deselected.
Frames
All instructions which refer to the workpiece coordinate system are permissible (FRAME, tool
radius compensation). Unlike the procedure for inactive transformation, however, a frame
change with G91 (incremental dimension) is not specially treated. The increment to be
traversed is evaluated in the workpiece coordinate system of the new frame - regardless of
which frame was effective in the previous block.
Extensions
When the oblique angle transformation (TRAANG) is selected and deselected, the assignment
between geometry axes and channel axes can change. The user can apply these geometric
contour sections to the axial frame as a translation, rotation, scaling and mirroring in relation to
the x and z planes with respect to the inclined infeed axis.

Function Manual Basic Functions; Axes, coordinate systems, frames
Unusable functions
The following functions cannot be used in channel axes involved in the transformation:
● Set actual value (PRESETON)
● Travel to fixed stop (FXS)
● Reference point approach (G74 or manual reference point approach)
