Cycles: Turning | THREAD EXTENDED (Cycle 832, DIN/ISO: G832)

Cycle parameters

Q471 Thread position (0=ext./1=int.)?: Define
the position of the thread:
0: External thread
1: Internal thread
Q461 Thread orientation (0/1)?: Define the
direction of the thread pitch:
0: Longitudinal (parallel to the rotary axis)
1: Lateral (perpendicular to the rotary axis)
Q460 Set-up clearance?: Set-up clearance
perpendicular to thread pitch.
Q472 Thread pitch?: Pitch of the thread
Q473 Thread depth (radius)? (incremental):
Depth of the thread. If you enter 0, the depth is
assumed for a metric thread based on the pitch
Q464 Dimension type taper (0-4)?: Define the
dimensioning of 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
Q491 Diameter at contour start?: X coordinate of
the contour starting point (diameter value)
Q492 Contour start in Z?: Z coordinate of the
starting point
Q493 Diameter at end of contour?: X coordinate
of the end point (diameter value)
Q494 Contour end in Z?: Z coordinate of the end
point
Q469 Taper angle (diameter)? Taper angle of the
contour
Q474 Length of thread runout? (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.
