Command for the activation of the independent axis-specific diameter
programming
The effect of DIAMONA is independent of the programmed dimensions
mode (G90/G91 or AC/IC):
• for G90, AC: Dimensions in the diameter
• for G91, IC: Dimensions in the diameter
Command for the activation of the dependent axis-specific diameter
programming
The effect of DIAM90A depends on the programmed dimensions mode:
• for G90, AC: Dimensions in the diameter
• for G91, IC: Dimensions in the radius
Command for the deactivation of the axis-specific diameter programming
Axis-specific radius programming takes effect when diameter
programming is deactivated. The effect of DIAMOFA is independent of the
programmed dimensions mode:
• for G90, AC: Dimensions in the radius
• for G91, IC: Dimensions in the radius
Command for the deactivation of axis-specific diameter programming
during cycle processing.
In this way, computations in the cycle can always be made in the radius.
The last G function active in this group remains active for the position
indicator and the basic block indicator.
Axis identifier of the axis for which the axis-specific diameter
programming is to be activated
Permitted axis identifiers are as follows:
• Geometry/channel axis name
or
• Machine axis name
Range of The axis specified must be a known axis in the
values: channel.
Other conditions:
• The axis must be permitted for the axis-specific
diameter programming via
MD30460 $MA_BASE_FUNCTION_MASK.
• Rotary axes are not permitted to serve as
transverse axes.
