Frame
A frame change with
transformation. The path to be traversed is evaluated in the workpiece coordinate system of
the new frame - regardless of which frame was active in the previous block.
A rotary axis offset can, for example, be entered by compensating the inclined position of a
workpiece can be considered using a frame or as offset of the rotary axis.
The following setting is required for the axial complete frame of the rotary axis to act in the
transformation:
$MC_TRACYL_ROT_AX_FRAME_<t> = 1
Note
Changes in the axis assignments are converted every time the transformation is selected or
deselected.

Function restriction for transformation axes
The axes involved on the cylinder surface transformation must not be used for the following
functions:
● Positioning axis
● Oscillating axis
● Preset axis
● Fixed point approach
● Reference point approach
Manual traversal in JOG
When generated cylinder surface transformation with groove side compensation
($MC_TRAFO_TYPE = 513) is active in JOG mode, it must be noted that the axes are
traversed depending on the preceding status in
compensation, the axes so move differently than for deselected compensation. The part
program can therefore be continued (
