Cycle parameters

Q497 Precession angle?: Angle to which the
TNC aligns the tool. Input range 0 to 359.9999
Q498 Reverse tool (0=no/1=yes)?: Mirror tool
for inside/outside machining. Input range 0 and 1.
Q530 Inclined machining?: Position the tilting
axes for inclined machining:
0: Maintain position of tilted axes (axis must
already have been positioned)
1: Position the tilting axis automatically and
orient the tool tip (MOVE). The relative position
between the workpiece and tool 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 later in a separate positioning block
(STAY). The TNC stores the position values in
the parameters Q120 (A axis), Q121 (B axis) and
Q122 (C axis).
Q531 Angle of incidence?: Angle of incidence
for aligning the tool. Input range: -180° to +180°
Q532 Feed rate for positioning?: Traverse
speed of the tilting axis during automatic
positioning. Input range 0.001 to 99999.999
