SECTION 11 PROGRAMMING FOR SIMULTANEOUS 4-AXIS CUTS (2S Model)
•
Determine the cutting conditions so that a total of the cutting power required by the two turrets
will not exceed the capacity of the machine.
Other considerations
•
The use of the INDIVIDUAL switch allows the turrets to be operated independently, facilitating
checking of trial cuts.
•
Care should be taken to avoid interference:
•
Interference between the boring bar and the chuck
•
When performing end face cutting with the tools on turret A:
Interference between tools on turret A and boring bar on turret B,
Interference between tools on turret A and ID toolholder on turret B
•
Program movements of the tools on turret B taking into account those of turret A.
G02 and G03 should also be programmed taking cutting with the tools on turret A into account.
•
In constant speed cutting mode operation called for by G96, G110 and G111 select the turret on
which constant cutting speed is obtained: G96 G111 calls for constant speed cutting for turret B
and G96; G110 cancels G96 G111 and selects constant speed cutting mode on turret A.
This feature generates large differences in cutting speeds for the tools on turrets A and B when,
for example, performing simultaneous cutting on a workpiece with large diameter differences.
Therefore, the cutting portion handled by each turret and the cutting tip material should be
selected very carefully.

The G96
S, M and P commands of
turrets A and B must match.
Even when the constant
speed cutting mode is in
effect, it is active only on
turret A and turret B is
not this mode.
