I
——
it is X moving distance(diameter value) when executing the thread run-out. Unit: mm. When
there is K and I is omitted, the system defaults I=2×K( 45° thread run-out) and I is not
negative.
D ——rotary machining depth.
（
unit: mm
）
When G04 is with others, D is the delay time. When there is no K, there is no D, otherwise,
the system prompts “ILLEGAL PARAMETER”. K=0, I, D are invalid. When the taper
thread is machined, rotary machining cannot be used, i.e. there is no D, otherwise the
system prompts “ILLEGAL PARAMETER”.
The metric/inch straight thread, taper thread, inner and outer thread can be machined by G33.
When X （ U ） are not zero in G33, the taper thread is machined. When the spindle rotates
clockwise, the right-hand thread is cut positively and the left-hand thread is cut negatively.
When the spindle rotates counterclockwise, they are opposite.
Fig. 9 G33 thread cutting
1. G33 axial straight thread is as Fi.g 9-1
K sign decides the direction of the thread run-out; there is no the thread run-out when K is
omitted; when there is no I, I=2K.
For example
：
G00 Z100 X100 ； G33 W-40 K3 I5 P2 ； end point (Z60
，
X105)
2. G33 axial rotary machining straight thread: as Fig. 9-2.
K sign decides the direction of the rotary machining and the thread run-out; K cannot be omitted;
when there is no I, I=2K.
