Transmit Configuration - Siemens SINUMERIK 808D Function Manual

ZM Z machine axis (linear)
XM X machine axis (linear)
CM C axis (main spindle as rotary axis)
Required machine kinematics
The two linear axes (XM, ZM) must be mutually perpendicular. The rotary axis (CM) must travel parallel to the linear axis ZM
(rotating around ZM). The linear axis XM intersects the rotary axis CM (center of rotation).
Activation/de-activation of TRANSMIT
The TRANSMIT function is activated in the program with
● TRANSMIT in a separate block and de-activated with
● TRAFOOF in a separate block
TRAFOOF deactivates any active transformation function.

Explanation:
The movement of the machine axes XM and CM produces the contour on the face-end of the turned part with the milling
cutter in accordance with the X-Y path programmed (straight or circular path). The programmed Z axis (infeed) continues to
be traversed as the Z axis.

TRANSMIT configuration

Machine data
The names of the machine data, channel axes and geometry axes from the general machine data ($MN_AXCONF...) and
channel-specific machine data ($MC_AXCONF...) are also used for a transformation.
The geometry axis assignments specified in MD20050 AXCONF_GEOAX_ASSIGN_TAB only apply when the transformation
is de-activated. Additional assignments are specified for a transformation.
Note
The assigned machine axis names, channel axis names and geometry axis names must differ:
MD10000 AXCONF_MACHAX_NAME_TAB,
•
MD20080 AXCONF_CHANAX_NAME_TAB,
•
MD20060 AXCONF_GEOAX_NAME_TAB.
•
Exception for TRANSMIT:
The axis names of MD20060 and MD20080 (geometry and channel axes) can be the same, e.g. X, Y, Z. No Y axis exists
here outside the transformation.
