Program spindle speed
Refer to your machine manual.
If you machine at constant cutting speed, the selected
gear range limits the possible spindle speed range.
The possible gear ranges (if applicable) depend on your
machine.
With turning you can machine both at constant spindle speed and
constant cutting speed.
If you machine at constant cutting speed
VCONST:ON
, the control
modifies the speed according to the distance of the tool tip to the
center of the turning spindle. For positioning movements toward
the center of rotation, the control increases the table speed; for
movements away from the center of rotation, it reduces the table
speed.
For processing with constant spindle speed
VCONST:Off
, speed is
independent of the tool position.
Use
FUNCTION TURNDATA SPIN
to define the speed. The control
provides the following input parameters:
VCONST: Constant cutting speed on/off (obligatory)
VC: Cutting speed (optional)
S: Nominal speed if no constant cutting speed is active
(optional)
S MAX: Maximum speed with constant cutting speed (optional).
Reset with S MAX 0
GEARRANGE: Gear range for the turning spindle (optional)
