3.1 Flexible NC programming
Examples
Example 1: Indirectly programming a spindle number
Direct programming:
Program code
S1=300
Indirect programming:
Program code
DEF INT SPINU=1
S[SPINU]=300
Example 2: Indirectly programming an axis
Direct programming:
Program code
FA[U]=300
Indirect programming:
Program code
DEF AXIS AXVAR2=U
FA[AXVAR2]=300
Example 3: Indirectly programming an axis
Direct programming:
Program code
$AA_MM[X]
Indirect programming:
Program code
DEF AXIS AXVAR3=X
$AA_MM[AXVAR3]
Example 4: Indirectly programming an axis
Direct programming:
Program code
X1=100 X2=200
