I – 2 Controlling the Constant

Surface Speed (CSS)

In CSS mode, a constant surface cutting speed can be maintained on
a lathe. The following functions are available:

„

CSS mode: The DAC output signal provides constant surface speed
by adjusting the spindle speed as the diameter (radius) of the
workpiece changes.

„

Direct entry of spindle speed: The DAC output signal sets the
spindle speed based on the value entered via the numeric keypad.

„

Speed limits: The user may set a safe operating range (minimum
and maximum speeds) for spindle speed.

„

Gear selection: Three different gears can be specified for varying the
relation between the actual speed and the DAC output signal.
