Fundamentals
2.8 Geometry settings
DAC:
DIC:
RAC:
RIC:
Note
With DIAMONA[<axis>] or DIAM90A[<axis>], the transverse-axis actual values are
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
During the replacement of an additional transverse axis because of a GET request, the status
of the diameter/radius programming in the other channel is accepted with RELEASE[<axis>].
Examples
Example 1: Modal axis-specific diameter/radius programming
X is the transverse axis in the channel, axis-specific diameter programming is permitted for Y.
Program code
N10 G0 X0 Z0 DIAMON
N15 DIAMOF
N20 DIAMONA[Y]
N25 X200 Y100
N30 DIAMCHANA[Y]
N35 X50 Y100
N40 DIAMON
N45 X50 Y100
Example 2: Non-modal axis-specific diameter/radius programming
X is the transverse axis in the channel, axis-specific diameter programming is permitted for Y.
Program code
N10 DIAMON

The DAC command sets the following dimensions to non-modal for the specified
axis:
Diameter in absolute dimensions
The DIC command sets the following dimensions to non-modal for the specified
axis:
Diameter in incremental dimensions
The RAC command sets the following dimensions to non-modal for the specified
axis:
Radius in absolute dimensions
The RIC command sets the following dimensions to non-modal for the specified
axis:
Radius in incremental dimensions
Comment
; Channel-specific diameter programming active for X.
; Channel-specific diameter programming off.
; Modal axis-specific diameter programming active for Y.
; Radius programming active for X.
; Y accepts the status of the channel-specific diameter/
radius programming and is assigned to this.
; Radius programming active for X and Y.
; Channel-specific diameter programming on.
; Diameter programming active for X and Y.
Comment
