Cycle parameters

Thread position Q471: Define the position of the
thread:

0

: External thread

1

: Internal thread

Thread orientationQ461: Define the direction of
the thread pitch:

0

: Longitudinal (parallel to the rotary axis)

1

: Lateral (perpendicular to the rotary axis)

Set-up clearance Q460: Set-up clearance
perpendicular to thread pitch.
Thread pitch Q472: Pitch of the thread.
Depth of thread Q473 (incremental): Depth of the
thread. If you enter 0, the depth is assumed for a
metric thread based on the pitch.
Dimension type of taper Q464: Define the type of
dimension for the taper contour:

0

: Via starting point and end point

1

: Via end point, start-X and taper angle

2

: Via end point, start-Z and taper angle

3

: Via starting point, end-X and taper angle

4

: Via starting point, end-Z and taper angle

Diameter at contour start Q491: X coordinate of
the contour starting point (diameter value)
Contour start in Z Q492: Z coordinate of the
starting point
Diameter at end of contour Q493: X coordinate of
the end point (diameter value)
Contour end in Z Q494: Z coordinate of the end
point
Taper angle Q469: Taper angle of contour
Runout of thread Q474 (incremental): 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.
Approach path Q465 (incremental): 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.
Overrun path Q466: Length of the path in pitch
direction on which the feed axes are decelerated.
The overrun path is within the defined thread
contour.
Maximum cutting depth Q463: Maximum plunging
depth perpendicular to the thread pitch
