3.8.6 Basic operation. Thread repair
Cycle definition
Define the dimensions of the thread like at the rest of the levels and the coordinates of one of the
roots.
With the spindle stopped, take the tool to be used for thread repair to one of the roots of the thread.
Once there, take these 2 values:
• Z coordinate of the valley (root).
Place the focus on the data and press [RECALL] [ENTER].
• Spindle angular position at the valley (root).
Place the focus on the data and press [RECALL] [ENTER].
The CNC assumes these 2 data needed for thread repair.
Machining steps
The machining steps for this cycle are identical to those for taper threading described earlier. The
CNC will make a new thread over the existing one, maintaining the roots and inclinations of the
current thread.
To do a thread repair, proceed as follows:
1. The spindle must have been oriented (M19) at least once since the CNC was turned on.
2. Take the Z coordinate values (teach-in) and the angular position of the spindle at the root of the
thread, parameters K W, while the tool is positioned at one of the roots of the thread to be
repaired.
3. Define the cycle for thread repair.
4. Execute (run) the cycle.
To define the coordinates of the root, the CNC must know the position of the spindle. The
spindle must be oriented in order for the CNC to know the spindle position. On CNC
power-up, it's enough to do this once.
