Cycle parameters
PRECESSION ANGLE Q497: Angle to which the
TNC aligns the tool. Input range 0 to 359.9999
REVERSE TOOL Q498: mirror tool for inside/
outside machining. Input range 0 and 1.
Inclined machining Q530: Position the tilting axes
for inclined machining:
0 : The position of the tilting axis (axis must have
been positioned before) remains unchanged
1 : Position the tilting axis automatically, thereby
orienting the tool tip (MOVE). The relative
position between the tool and workpiece remains
unchanged. The TNC performs a compensating
movement with the linear axes
2 : Position the tilting axis automatically without
orienting the tool tip (TURN)
3 : Do not position the tilting axis. Position
the tilting axes in a subsequent and separate
positioning block (STAY). The TNC stores the
position values in the parameters Q120 (A axis),
Q121 (B axis) and Q122 (C axis).
Angle of incidence Q531: Angle of incidence for
aligning the tool. Input range: -180° to +180°
Feed rate for positioning Q532: Traverse speed
of the tilting axis during automatic positioning.
Input range 0.001 to 99999.999
Preferred direction Q533: Selection of alternate
possibilities of inclination. The angle of incidence
you have defined is used by the TNC to calculate
the appropriate positioning of the tilting axes
present on the machine. In general there are
always two possible solutions. Use the parameter
Q533 to specify which solution the TNC should
use:
0 : Select the solution using the shortest path
-1 : Select the solution in the negative direction
+1 : Select the solution in the positive direction
