12.2 Defining a geometry axis as transverse axis

12.2 Defining a geometry axis as transverse axis
Definition of a transversing axis in the channel
The definition of one geometry axis as transverse axis is realized using machine data:
MD20100 $MC_DIAMETER_AX_DEF (geometry axis with transverse axis function?)
Example:
MD20100
$MC_DIAMETER_AX_DEF="X"
For this axis, diameter programming and assigning a constant cutting speed with G96/G961/G962 are both
permitted.
Several transverse axes in the channel
The axis-specific machine data:
MD30460 BASE_FUNCTION_MASK (axis functions)
allows the definition of additional transverse axes, for which the functionality of the axis-specific diameter
programming is permitted:
Bit Value Meaning
2 0 Axis-specific diameter programming is not permitted.
1 Axis-specific diameter programming is permitted.
Note
The setting MD30460 bit 2 = 1 is only possible for linear axes.
An axis can be simultaneously defined in MD20100 and in MD30460 (bit 2). For this, the channel-specific
MD20100 has a higher priority than the axis-specific MD30460.
With:
• MD20100, the function G96/G961/G962 is assigned to the transverse axis during power up.
• MD20100, the channel-specific diameter programming DIAMON, DIAMOF, DIAM90, DIAMCYCOF is
assigned to the transverse axis during power up.
After power up, this axis has the axis-specific basic position DIAMCHANA[AX].
• MD30460 bit2 the additional enabling of the axis-specific operations DIAMONA[AX], DIAMOFA[AX],
DIAM90A[AX], DIACYCOFA[AX], DIMCHANA[AX].
