Cycle run
The TNC cuts the thread without a floating tap holder in one or more
passes.
1 The TNC positions the tool in the spindle axis at rapid traverse FMAX
to the entered set-up clearance above the workpiece surface.
2 The tool taps to the total hole depth in one movement.
3 Once the tool has reached the total hole depth, the direction of
spindle rotation is reversed and the tool is retracted to the set-up
clearance at the end of the dwell time. If programmed, the tool
moves to the 2nd set-up clearance at FMAX.
4 The TNC brings spindle rotation to a stop at the set-up clearance.
