Threadcut cycle group
Tapered thread G353
This cycle cuts a tapered single- or multi-start thread. The thread
begins at “XS, ZS“ and ends at “X, Z“.
Parameters
XS,ZS: Starting point of thread (XS as diameter)
X, Z: End point of thread (X as diameter)
F: Thread pitch
U: Thread depth
U>0: Internal thread
U<=0: External thread on longitudinal, transverse or rear side
I: Maximum infeed – default: I is calculated from the thread pitch
and the thread depth
A: Approach angle – default: 30°; Range: –60° < A < 60°
• A>0: Infeed from right thread flank
• A<0: Infeed from left thread flank
D: No. gears – Number of grooves – default: 1
W: Cone angle – default: 0°; Range: –45° < W < 45°
WE: Run-out angle – default: 12°; Range: 0° < WE < 90°
J: Remaining cutting depth – default: 1/100 mm
•“Cycle STOP“ only becomes effective at the end of a thread cut.
• The feed rate and spindle speed overrides are disabled during
execution of the cycle.
• Permissible parameter combinations for defining the
cone angle:
• XS/ZS, X/Z
• XS/ZS, Z, W
• ZS, X/Z, W
