Radius / diameter dimensions: DIAMOF, DIAMON, DIAM90

Functionality
For machining parts, the positional data for the X–axis (transverse axis) is programmed as
diameter dimensioning. When necessary, it is possible to switch to radius dimensioning in
the program.
DIAMOF or DIAMON assesses the end point specification for the X axis as radius or
diameter dimensioning. The actual value appears in the display accordingly for the
workpiece coordinate system.
For DIAM90, irrespective of the traversing method (G90/G91), the actual value of the
transverse axis is always displayed as a diameter. This also applies to reading of actual
values in the workpiece coordinate system with MEAS, MEAW, $P_EP[x] and $AA_IW[x].
