A. Constant surface speed control ON
1. Command
This function controls automatically the spindle speed as the coordinates are changed
during cutting in diametral direction so as to execute cutting by keeping constant the relative
speed between tool tip and workpiece.
Axis for constant surface speed control
(P1: X-axis, P2: Y-axis)
Spindle for constant surface speed control
(R1: Turning spindle, R2: Turning spindle)
2. Notes
The last value of Ss in the control mode of G96 is stored during cancellation of the
control (G97) and automatically made valid upon resumption of the control mode
(G96).
Cancellation of the control mode (G96) by a command of G97 without specification of
Ss (revs/min) retains the spindle speed which has resulted at the end of the last
spindle control in the G96 mode.
The constant surface speed control does not apply to the milling spindle.
B. Constant surface speed control OFF (Constant speed)
1. Command
Spindle speed (min
-1
) is controlled
