Frame for selection and deselection of transformations
This function is available with NCK 51.00.00 and higher. Transformations TRANSMIT, TRACYL and TRAANG
are supported.
As a rule, the assignment of geometry axes to channel axes changes when selecting and deselecting
transformations. It is not possible to uniquely assign axial frame components to geometric contour frame
components when carrying out transformations, in which rotary axes become linear axes and vice versa. The
contour frame must be conditioned using special treatment for such non-linear transformations.
The mode, set with MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 1 and 2, is expanded in such a way as
to take the above transformations into account.
When selecting transformations, the contour frame is connected to the axial frames. With transformations
TRANSMIT, TRACYL and TRAANG, the virtual geometry axis is subject to special treatment.
TRANSMIT
Transmit expansions:
The machine data below can be used to take the axial complete frame of the TRANSMIT rotary axis, i.e., the
translation, fine offset, mirroring and scaling, into account in the transformation:
MD24905 $MC_TRANSMIT_ROT_AX_FRAME_1 = 1
MD24955 $MC_TRANSMIT_ROT_AX_FRAME_2 = 1
A rotary axis offset can, for example, be entered by compensating the oblique position of a workpiece in a frame
within a frame chain. As a rule, this offset can also be included in the transformation as an offset in the rotary
axis. A c axis offset, as in the figure above, then leads to corresponding x and y values.
NOTICE
Transformations with virtual axes
When selecting TRANSMIT or TRACYL, offsets, scaling and mirroring of the real Y axis are
not transferred and accepted in the virtual Y axis. Offsets, scaling and mirroring of the virtual
Y axis are deleted for TRAFOOF.
