Q rules:
1. Its initial angle is 0° if Q is not specified;
2. For continuous thread cutting, Q specified by its following thread cutting block except for the
first block is invalid, namely Q is omitted even if it is specified;
3. Multi threads formed by initial angle is not more than 65535;
4. Q unit : 0.001
0
. Q180000 is input in program if it offsets 180
0
with spindle one-turn; if Q180 or
Q180.0, it is 0.18°.
Difference between long axis and short axis is shown in Fig. 3-38.

Notes:
● J, K are modal. The thread run-out is previous J, K value when they are omitted in the next
block in continuous thread cutting. Their mode are cancelled when no thread cutting are
executed;
● There is no thread run-out when J, or J, K are omitted; K=J is the thread run-out value when K
is omitted;
●
There is no thread run-out when J=0 or J=0, K=0;
● The thread run-out value J=K when J ≠ 0,K=0;
● There is no thread run-out when J=0 or K ≠ 0;
●
If the current block is for thread and the next block is the same, the system does not test the
spindle encoder signal per rev at starting the next block to execute the direct thread cutting,
which function is called as continuous thread machining;
●
After the feed hold is executed, the system displays “Pause” and the thread cutting
continuously executes not to stop until the current block is executed completely; if the
continuous thread cutting is executed, the program run pauses after thread cutting blocks are
executed completely;
●
In Single block, the program stops run after the current block is executed. The program stops
running after all blocks for thread cutting are executed;
