MD24210 TRAFO_AXES_IN_2[n]
Channel axes for transformation 2
MD24220 TRAFO_GEOAX_ASSIGN_TAB_2[n]
Geometry axes for transformation 2
Required assignment of channel axes for TRANSMIT transformation in machine data MD24110/MD24210:
Channel axis number of axis perpendicular to rotary axis
Channel axis number of rotary axis
Channel axis number of axis parallel to rotary axis
Machine data specifically for TRANSMIT
● MD24900 TRANSMIT_ROT_AX_OFFSET_1
Rotational position of Cartesian coordinate system x-y plane with respect to the defined zero position of rotary axis in
degrees (0... < 360)
● MD24910 TRANSMIT_ROT_SIGN_IS_PLUS_1
If the rotary axis rotates in an anti-clockwise direction on the X-Y plane opposite to the positive Z axis, then the MD must
be set to 1, otherwise to 0.
Direction of rotation for MD value = 1:
● MD24920 TRANSMIT_BASE_TOOL_1
The control is informed of the position of the tool zero point in relation to the origin of the coordinate system declared for
TRANSMIT. The MD has three components for the three axes of the Cartesian coordinate system.
Assignment of axis components:
TRANSMIT_BASE_TOOL_1[0]=Tx
TRANSMIT_BASE_TOOL_1[1]=Ty
TRANSMIT_BASE_TOOL_1[2]=Tz (see following figure)
Position of tool zero in relation to origin of the Cartesian coordinate system (center of rotation):
● MD24911 TRANSMIT_POLE_SIDE_FIX_1 = 0
Pole traversal continuous
The pole is defined as the center of rotation at point X=0, Y=0 of TRANSMIT plane (X machine axis intersects the center of
rotation).
In the vicinity of the pole, small positional changes in the geometry axes X, Y generally result in large changes in the
machine rotary axis position (exception: path only results in a movement of the XM axis).
Workpiece machining operations close to the pole are therefore not recommended since these may require sharp feedrate
reductions to prevent overloading of the rotary axis. Avoid selecting TRANSMIT when the tool is positioned exactly on the
pole. Ensure that the path of the tool center point does not travel through the X0/Y0 pole.
