Cycle parameters
U Thread position Q471: Define the position of the
thread:
0: External thread
1: Internal thread
U Thread orientation Q461: Define direction of the
thread pitch:
0: Longitudinal (parallel to rotary axis)
1: Transverse (perpendicular to rotary axis)
U Set-up clearance Q460: Set-up clearance
perpendicular to thread pitch.
U Thread pitch Q472: Pitch of the thread.
U Depth of thread Q473: Depth of the thread. If you
enter 0, the depth is assumed for a metric thread
based on the pitch.
U Runout of thread Q474: Length of the path on which,
at the end of the thread, the tool is lifted from the
current plunging depth to the thread diameter Q460.
U Approach path Q465: Length of the path in pitch
direction on which the feed axes are accelerated to
the required velocity. The approach path is outside of
the defined thread contour.
U Overrun path Q466: Length of the path in pitch
direction on which the feed axes are decelerated. The
overrun path is outside the defined thread contour.
U Maximum cutting depth Q453: Maximum plunging
depth perpendicular to the thread pitch
U Angle of infeed Q467: Angle for the infeed Q453. The
reference angle is formed by the parallel line to the
thread pitch.
