Dimensional information for transverse axes

Transverse axes can be programed 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.

Transverse axis with diameter information (D1, D2)

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:

• DIAMCYCOF: Radius programming for G90 and G91 ON , for the HMI, the last active G

Reference is made exclusively to the transverse axis of the channel.

Axis-specific diameter programming for several transverse axes in one channel

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.
