The workpiece is clamped, the probe advances, contacts the positioning groove, and the table rotates after 8 s. The workpiece is detected. After the first groove width is detected, the rotation is stopped, and the measurement data is sent to the CNC for processing, and the probe returns.

The workbench converts the value calculated by the CNC to the machining position, and uses the machine coordinate of the current C axis as the origin of the C axis workpiece coordinate. The worktable is hung tightly, and an in-position signal is sent after being hung in place.
