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