To execute the constant surface speed control, it is necessary to set the
work coordinate system, and so the coordinate value at the center of the
rotary axis, for example, Z axis, (axis to which the constant surface speed
control applies) becomes zero.

Not specified
The surface speed (m/min or

Command
for the surface
speed
The stored surface speed (m/min or
feet/min) is used. If no surface speed is
stored, 0 is assumed.

In a rapid traverse block specified by G00, the constant surface speed
control is not made by calculating the surface speed to a transient change
of the tool position, but is made by calculating the surface speed based on
the position at the end point of the rapid traverse block, on the condition
that cutting is not executed at rapid traverse.
