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].

Note
A programmable offset with TRANS X... or ATRANS X... is always evaluated as radius dimensioning. Description of this
function: see the next section.
8.2.5

Programmable work offset: TRANS, ATRANS

Functionality
The programmable work offset can be used:
● for recurring shapes/arrangements in various positions on the workpiece
● when selecting a new reference point for the dimensioning
● as a stock allowance when roughing
