Value Meaning
Orientation axes with Hirth joint
Bit 4: 1st orientation axis
Bit 5: 2nd orientation axis
Bit 6: 3rd orientation axis
0 The orientation axis is not Hirth-coupled.
1 The orientation axis is Hirth-coupled.
Note
● Parameters of the Hirth joint
The following machine data is evaluated for the parameters of the Hirth joint:
– MD30501 $MA_INDEX_AX_NUMERATOR
– MD30502 $MA_INDEX_AX_DENOMINATOR
– MD30503 $MA_INDEX_AX_OFFSET
MD30505 $MA_HIRTH_IS_ACTIVE is not evaluated. I.e. the axis does not
have to be parameterized as a genuine Hirth axis.
● Modulo rotary axes
For modulo rotary axes (MD30310 $MA_ROT_IS_MODULO==TRUE),
MD30330 $MA_MODULO_RANGE is evaluated instead of MD30501
$MA_INDEX_AX_NUMERATOR. The distances of the permitted axis positions
are then calculated for:
Distance = $MA_MODULO_RANGE / $MA_INDEX_AX_DENOMINATOR
MD30503 $MA_INDEX_AX_OFFSET is also evaluated for modulo rotary axes
7 An additional constant element of the type "OFFSET" is automatically NC-internally inserted
into the subchain for the workpiece reference point in such a way that the chain is closed.
0 The element connects the workpiece reference point to the machine zero point.
1 The element connects the end point of the element that is referenced
by $NT_CLOSE_CHAIN_P (Page 292) to the machine zero point.
8 An additional constant element of the type "OFFSET" is automatically NC-internally inserted
into the subchain for the tool reference point in such a way that the chain is closed.
0 The element connects the tool reference point to the machine zero point.
1 The element connects the end point of the element that is referenced
by $NT_CLOSE_CHAIN_T (Page 293) to the machine zero point.
9 The scope of functions of TRANSMIT or TRACYL transformations is specified more precise‐
ly. If a center offset axis has been specified via $NT_ROT_AX_NAME, the behavior can be
set.
0 The center offset axis can be interpolated in any way and has no influence on the
transformation.
1 The center offset axis compensates the tool offset in the Y direction. Processing up
to the center of rotation is possible.
0 Parameterizes TRACYL without slot side offset.
1 Parameterizes TRACYL with slot side offset.
In connection with bit 9 = 1, you can set whether TRACYL is operated with or
without slot side offset upon activation of the transformation via TRAFOON. The
default setting is slot side offset active
If you are working with slot side offset, $NT_GEO_AX_NAME must contain a ref‐
erence to a linear axis (slot side offset axis).
