Examples
Example 1: Activating the constant cutting speed with speed limitation
Program code Comment
N10 SETMS (3)
N20 G96 S100 LIMS=2500 ; Constant cutting speed = 100 m/min,
max. speed = 2500 rpm
...
N60 G96 G90 X0 Z10 F8 S100 LIMS=444 ; Max. speed = 444 rpm
Example 2: Defining speed limitation for four spindles
Speed limitations are defined for spindle 1 (master spindle) and spindles 2, 3, and 4:
Program code
N10 LIMS=300 LIMS[2]=450 LIMS[3]=800
LIMS[4]=1500
...
Example 3: Y-axis assignment for face cutting with X axis
Program code Comment
N10 G18 LIMS=3000 T1 D1 ; Speed limitation at 3000 rpm
N20 G0 X100 Z200
N30 Z100
N40 G96 S20 M3 ; Constant cutting speed = 20 m/min, is dependent
upon X axis.
N50 G0 X80
N60 G1 F1.2 X34 ; Face cutting in X at 1.2 mm/revolution.
N70 G0 G94 X100
N80 Z80
N100 T2 D1
N110 G96 S40 SCC[Y] ; Y axis is assigned to G96 and G96 is activated (can
be achieved in a single block). Constant cutting
speed = 40 m/min, is dependent upon X axis.
...
N140 Y30
N150 G01 F1.2 Y=27 ; Plunge-cutting in Y, feedrate F = 1.2 mm/revolution.
N160 G97 ; Constant cutting speed off.
N170 G0 Y100
