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

Workpiece surface coordinate

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.
