Fig. 3-84 G32.1 path
Notes ：
1) The spindle must be in the position control mode when it works;
2) 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;
3) 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;
4) Absolute coordinates of C axis are set to the cycle mode to avoid the coordinate
overflow;
5) 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:
