Thread cutting Quick feeding Z axis X axis
Execution process:
1) X axis locates (G0) to cutting start quickly from cycle start;
2) Interpolate to thread end from cutting start;
3) X axis radially back to radial coordinate position of cycle start in quick positioning (G0)
mode;
4) Z axis quickly locates (G0) and returns to the start point, and cycle ends.
Function description:
1) G92 instruction function is similar to G32 function, and only cycle cutting function is
increased.
2) U, W, and R reflect the relative position of cutting end and start. G92 has four track
combinations depending on the sign.
3) During first tool cutting, if U is 0, current value is the end coordinates by default; W can’t
be 0, or else the system alarms
4) Principal axis ratio control is invalid during thread cutting
5) If the converted feeding speed every minute exceeds the maximum feeding speed, the
system alarms
6) G92 instruction can process one thread in several times of feeding, but the processing of
two continuous threads can’t be realized, nor process endd thread. G92 instruction thread
pitch has the same definition as G32, and the pitch is the displacement of the long axis that
the principal axis rotates one circle (X axis displacement depends on the radius).
