Cycle parameters

Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface. Input
range 0 to 99999.9999
Q201 Depth of thread? (incremental): Distance
between workpiece surface and root of thread.
Input range -99999.9999 to 99999.9999
Q239 Pitch?: Pitch of the thread. The algebraic
sign differentiates between right-hand and left-
hand threads:
+
–= left-hand thread
Input range -99.9999 to 99.9999
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
