Parameters
Meanings
Remarks
DTB=0.7
Pause 0.7 s during final tapping to
thread depth (discontinuous cutting)
SDAC=5
Spindle state after cycle is M5
Enter values 3/4
→
M3/M4
PIT=2(Range of
values:0.001~2
000 mm)
Right hand thread with 2mm pitch
Evaluate value
→
left hand
thread
POSS=5
Spindle stops at 5º (unit: º)
SST=5
Tapping thread spindle speed is
5 r/min
SST1=5
Retraction spindle speed is 5 r/ min
Direction is opposite to SST
SST1=0
→
speed is same as
SST
SST and SST1 control the spindle speed and the Z axis feed position
synchronously. During execution of CYCLE 84, the switches of the
feed rate override and the cycle stop (feed hold) are deactivated.
