Tapping, axial/radial
Call the drilling menu.
Select the "Tapping, axial" cycle.
Select the "Tapping, radial" cycle.
With this cycle, you can tap a thread on the face / lateral surface of a
workpiece.
Meaning of "retraction length L": Use this parameter for floating tap
holders. The cycle calculates a new nominal pitch on the basis of the
thread depth, the programmed pitch, and the "retract length." The
nominal pitch is somewhat smaller than the pitch of the tap. During
tapping, the drill is pulled away from the chuck by the "retraction
length." With this method you can achieve higher service life from the
taps.
Cycle parameters
 X, Z starting point
 C spindle angle (C-axis position)—default: Current spindle angle
 F1 thread pitch (= feed rate)—default: Feed rate from tool
definition
 B run-in length (default: 2 * thread pitch F1) to reach the
programmed spindle speed and feed rate
 SR return speed (default: Same spindle speed as for tapping) for
enabling the tap to retract rapidly
 Retraction length L (default: 0) when using floating tap holders
 T tool number
 S spindle speed / cutting speed
Drilling axial:
 Z1 starting point of hole —default: Drilling starts from position Z
 Z2 end point of hole
Drilling radial:
 X1 starting point of hole —default: Drilling starts from position X
 X2 end point of hole
MANUALplus uses the tool parameter "driven tool" to
determine whether the programmed spindle speed and
feed rate apply to the spindle or the driven tool.
