Cycle parameters

Set-up clearance

Q200 (incremental): Distance

between tool tip (at starting position) and workpiece
surface. Input range 0 to 99999.9999; alternatively
PREDEF

Total hole depth

Q201 (incremental): Distance

between workpiece surface and end of thread. Input
range -99999.9999 to 99999.9999

Pitch

Q239

Pitch of the thread. The algebraic sign differentiates
between right-hand and left-hand threads:
+= right-hand thread
= left-hand thread
Input range -99.9999 to 99.9999

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
99999.9999; alternatively PREDEF

Retracting after a program interruption

If you interrupt program run during thread cutting with the machine
stop button, the TNC will display the MANUAL OPERATION soft key.
If you press the MANUAL OPERATION soft key, you can retract the
tool under program control. Simply press the positive axis direction
button of the active spindle axis.
