10. SPINDLE SPEED FUNCTION
G96 mode G97 mode
Specify the surface speed in m/min
Store the surface speed in m/min
(rpm) is used
The surface speed (m/min or
feet/min) is converted to the
spindle speed (rpm)
Commands other than G96
speed is used
for the surface
The stored surface speed (m/min or
feet/min) is used. If no surface speed is
stored, 0 is assumed.
The constant surface speed control is also effective during threading.
Accordingly, it is recommended that the constant surface speed control
be invalidated with G97 command before starting the scroll threading and
taper threading, because the response problem in the servo system may
not be considered when the spindle speed changes.
