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
N15 G0 G90 X20 Y40 DIAMONA[Y]
N20 G01 X=RIC(5)
N25 X=RAC(80)
N30 WHEN $SAA_IM[Y]> 50 DO POS[X]=RIC(1)
N40 WHEN $SAA_IM[Y]> 60 DO POS[X]=DAC(10)
N50 G4 F3
Further information
Diameter values (DIAMONA/DIAM90A)
The diameter values apply for the following data:
● Actual value display of the transverse axis in the workpiece coordinate system
● JOG mode: Increments for incremental dimensions and handwheel travel
● Programming of end positions:
Interpolation parameters I, J, K for G2/G3, if these have been programmed absolutely with
AC.
If I, J, K are programmed incrementally (IC), the radius is always calculated.
● Reading actual values in the workpiece coordinate system for:
MEAS, MEAW, $P_EP[X], $AA_IW[X]
Non-modal axis-specific diameter programming (DAC, DIC, RAC, RIC)
The statements DAC, DIC, RAC, RIC are permissible for any commands for which channel-
specific diameter programming is relevant:
● Axis position: X..., POS, POSA
● Oscillating: OSP1, OSP2, OSS, OSE, POSP
● Interpolation parameters: I, J, K
● Contour definition: Straight line with specified angle
