Note 1:
Max. R is not more than 4199 mm, otherwise the system cannot ensure its value is
right.
Note 2:
the system will test whether the current coordinates (starting point), the end point
coordinates and the center coordinates are right when it adopts K
, I
to execute the
programming. If the end point is not on the arc, and Z error will be more than 0.05 mm
or that of X will be more than 0.1 mm, the system alarms: “INCOMPATIBLE DATA”.
When the arc from the starting point to the end point is more than 180
°,
the system
alarm :“OVERTRAVEL”.
Note 3:
When the system adopts R programming and 2R is less than the distance from the
current point to the end point, otherwise the system alarms: “INCOMPATIBLE DATA”.

Thread Cutting
Command format
：
G33 X (U)_ Z (W)_ P (E)_ K_ I_ D_
；
X (U) Z (W)——absolute/incremental coordinate of thread end point( when X is omitted, it is the
straight thread).
P——metric thread lead. Unit: mm Range
：
0.25-100 mm
E——inch thread lead. Unit: tooth/inch Range
：
100-0.25 tooth
／
inch
K——X distance from the starting point to the end point of thread run-out. Unit: mm. When K is
omitted, do not execute the thread run-out.
When the straight thread K
＞
0 in machining and the thread run-out is being executed, X
positively moves; when K
＜
0 and the thread run-out is being executed, X negatively moves.
The sign of K in machining must be the same as X moving direction.
