cutting at 45°).
K : The axial distance on Z-axis from the start point to the end point for
the end of thread cutting.
L : Multiple-thread setting. Range:1~9. For G92 only.
”L” is a modular value and valid all the time once it is set. If L and
"Q" are set at the same time, the L-value will be regarded as invalid.
Q : Offset setting of the thread initial angle. Range: 0~359. For G92 only.
Fig. 3-27 G92 Linear Thread Cutting Canned Cycle
Details:
(1) The range of the thread lead and the speed limit of the spindle are same as G32
(thread cutting).
(2) Whenever the start button (CYCST) is pressed in a block, the tool moves along
the paths 1~2~3~4 to execute a cutting cycle.
(3) Subject to the restrictions of G32.
(4) Where a feed hold command is given during the cutting, the linear thread cutting
canned cycle does not stop until the cutting on path 3 is complete.

R : The difference between point B and C in radius.
X, Z, U, W, L, Q, F, E are identical to those of the linear thread cutting canned
cycle.
