Fig. 3-40 G32.1 path
Explanations
：
1) G32.1 is in Group 01;
2) When there is the C movement command in a block, the spindle firstly positions the
start point of C axis before turning the thread;
3) Start points of X, Z, C axis must be the same one in the repetitive machining;
4) G32.1 cannot specify the thread run-out, and the feed axis and the spindle stops
simultaneously at the end point of the thread;
5) The input range of the programmed address value in G32.1 is the same that of the
general thread turning command （ G32 ） ;
6) When G32.1 is executed, the pause signal is disabled temporarily and the spindle
override is fixed to be 100%.
Notes
：
●
The spindle must be in the position control mode when it works;
●
In multiple spindle control function, G32.1 is used only between the 1
st
spindle and the feed
axis, and their uses and the related parameter settings are the same those of the rigid
tapping;
●
In G32.1, CNC does not check whether the current spindle is the position control mode or the
speed control mode. So, the servo control axis of the 1
st
spindle is set to Cs working mode to
avoid the coordinate overflow;
●
Absolute coordinates of C axis are set to the cycle mode to avoid the coordinate overflow;
● The speed control mode is switched to the position control mode in the spindle control mode.
Please execute that the spindle returns to the reference point or use G50 to set the start point
of the current C axis;
Example: Supposing M14: the spindle is switched to the position control mode; M15: the spindle is
switched to the speed control mode.
The thread is the right-hand, its lead is 2mm, the spindle speed is 500 r/m in thread cutting,
thread cutting length is 20mm, and its programming format is shown below:
