9.9 G86. Longitudinal threading canned cycle
With this cycle it is possible to cut outside, inside and tapered threads.
The right-hand and left-hand threads will be programmed by indicating the direction of the spindle
rotation M03 or M04.
The basic structure of the block is as follows:
G86 X Z Q R K I B E D L C J A W V M
X±5.5
Defines the X coordinate of the initial point of the thread. It must be programmed in absolute
coordinates and in the active units, radius or diameter.
Z±5.5
Defines the Z coordinate of the initial point of the thread. It must be programmed in absolute
coordinates.
Q±5.5
Defines the X coordinate of the final point of the thread. It must be programmed in absolute
coordinates and in the active units, radius or diameter.
R±5.5
Defines the Z coordinate of the final point of the thread.
K±5.5
Optional. It is used with parameter "W" for thread repair.
Defines the Z coordinate of the point where the thread is to be measured. Usually it is an intermediate
point of the thread.
I±5.5
Defines the depth of the thread in radius. Its value must be positive for outside threads and negative
for inside ones.
If programmed with a 0 value, the CNC will display the corresponding error message.
