12.3 Dimensional information for transverse axes

12.3 Dimensional information for transverse axes
Transverse axes can be programmed with respect to both diameter and radius. Generally, they are diameter-
related, i.e. programmed with doubled path dimension so that the corresponding dimensional information can be
transferred to the part program directly from the technical drawings.

Switching the diameter programming on/off
Channel-specific diameter programming
The activating or deactivating of the diameter programming is done via the modally active parts program
statements of the G group 29:
• DIAMON: Diameter programming ON
• DIAMOF: Diameter programming OFF, in other words, radius programming ON
• DIAM90: Diameter or radius programming depending on the reference mode:
- Diameter programming ON in connection with absolute dimensioning G90
- Radius programming ON in connection with incremental dimensioning G91
• DIAMCYCOF: Radius programming for G90 and G91 ON , for the HMI, the last active G code of this group
remains active
Reference is made exclusively to the transverse axis of the channel.
Axis-specific diameter programming for several transverse axes in one channel
Note
The additionally specified axis must be activated via MD30460
$MA_BASE_FUNCTION_MASK with bit2=1.
The axis specified must be a known axis in the channel. Geometry, channel or machine axes
are permitted.
Programming is not permitted in synchronized actions.
The following axis-specific modal statements can be programmed several times in a parts program block:
