Cycle parameters
Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface. Input
range 0 to 99999.9999
Q201 Depth? (incremental): Distance between
workpiece surface and bottom of hole. Input range
-99999.9999 to 99999.9999
Q206 Feed rate for plunging?: Traversing speed
of the tool in mm/min while boring. Input range 0
to 99999.999, alternatively FAUTO, fu
Q211 Dwell time at the depth?: Time in seconds
that the tool remains at the hole bottom. Input
range 0 to 3600.0000
Q208 Feed rate for retraction?: Traverse speed
of tool when moving out of the hole in mm/min.
If you enter Q208 = 0, the feed rate for plunging
applies. Input range 0 to 99999.999, alternatively
Fmax, FAUTO
Q203 Workpiece surface coordinate? (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
Q204 2nd set-up clearance? (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
Q214 Disengaging directn (0/1/2/3/4)?:
Determine the direction in which the TNC
disengages the tool at the hole bottom (after the
spindle orientation)
0: Do not disengage the tool
1: Disengage the tool in a minus direction of the
reference axis
2: Disengage the tool in a minus direction of the
minor axis
3: Disengage the tool in a plus direction of the
reference axis
4: Disengage the tool in a plus direction of the
minor axis
Q336 Angle for spindle orientation? (absolute):
Angle to which the TNC positions the tool before
retracting it. Input range -360.000 to 360.000
