High-speed machining

22.7.1 High speed settings: Configuring CYCLE832
Function
The High Speed Settings function (CYCLE832) is used to preset data for the machining of
sculptured surfaces so that optimum machining is possible. The call of CYCLE832 contains
three parameters:
● Tolerance
● Machining type (technology)
● Input of the orientation tolerance
Tolerance / orientation tolerance
The tolerance value for the linear axes (geometry axes) is transferred to the CNC with the
NC command CTOL. CTOL = root(3) * tolerance value.
Tolerance value = 0: Tolerance value (CTOL) is loaded from the following SDs:
SD55446 $SCS_MILL_TOL_VALUE_ROUGH
SD55447 $SCS_MILL_TOL_VALUE_SEMIFIN
SD55448 $SCS_MILL_TOL_VALUE_FINISH
Example: CYCLE832(0,_ROUGH,1) → tolerance value from SD55446 is used.
If rotary axes are involved in the machining (multi-axis transformation), the tolerance value is
transferred to the CNC with the NC command OTOL.

The 3rd parameter is significant only for machines with multi-axis orientation
transformation (TRAORI). By default, it is assigned the value 1.
