3.23.8 Rigid Thread Cutting Cycle G92.1
Command format: G92.1 X(U)_ Z(W)_ F_ L S_
；
(Metric straight thread cutting cycle)
G92.1 X(U)_ Z(W)_ I_ L S_
；
(Inch straight thread cutting cycle)
G92.1 X(U)_ Z(W)_ R_ F_ L S_
；
(Metric taper thread cutting cycle)
G92.1 X(U)_ Z(W)_ R_ I_ L S_ ； (Metric taper thread cutting cycle)
Command function: Perform the radial (X axis) in-feed or axial (Z axis or X and Z axes) cutting
from the cutting start, simultaneously, the work of the spindle motor is identical with
the feed servo motor, as well the thread interpolation is performed by interpolation
between the feed axis and spindle; therefore, the higher accuracy thread is then
gained to achieve the cutting cycle of the straight thread of the constant pitch or the
cone thread.
Command specification:
G92.1 is modal;
Starting point of cutting: starting position of thread interpolation;
End point of cutting: end position of thread interpolation;
X: X absolute coordinate of end point of cutting, unit: mm;
U: Different value of X absolute coordinate from end point to starting point of cutting,
unit: mm;
Z: Z absolute coordinate of end point of cutting, unit: mm;
W: Different value of X absolute coordinate from end point to starting point of cutting,
unit: mm;
R: Different value (radius value) of X absolute coordinate from end point to starting
point of cutting. When the sign of R is not the same that of U, R │≤│ U/2 │ , unit: mm;
