Thread cutting cycle G92

Code format: G92 X (U)_ Z (W)_ F_ J_ K_ L; (Metric straight Thread cutting cycle)

G92 X (U)_ Z (W)_ I_ J_ K_ L; (Inch straight thread cutting cycle)

G92 )_ R_ F_ J_ K_ L; (Metric taper thread cutting cycle)

G92 X (U)_ Z (W)_ R_ I_ J_ K_ L; (Inch taper thread cutting cycle)

Code function: Starting from the cutting starting point, perform radial (X-axis) feed and axial (Z-axis or X and Z-axis simultaneously) cutting to realize equal-pitch straight thread and tapered thread cutting cycles. When the G92 code is executed, there is a thread retraction process at the end of thread machining: at a fixed length from the end of thread cutting (called the retraction length of the thread), while the Z axis continues thread interpolation, the X axis retracts along < /p>

The direction is exponential or linear (set by parameters) to accelerate the exit. After the Z-axis reaches the cutting end point, the X-axis retracts at the rapid traverse speed.

Code description: G92 is the modal G code;

Cutting starting point: the starting position of thread interpolation;

Cutting end point: the end of thread interpolation Position;

X: X-axis absolute coordinate of cutting end point, unit: mm;

U: Difference between X-axis absolute coordinate of cutting end point and starting point, unit: mm;

Z: The Z-axis absolute coordinate of the cutting end point, unit: mm;

W: The difference between the Z-axis absolute coordinates of the cutting end point and the starting point, unit: mm;

R : The difference (radius value) between the X-axis absolute coordinates of the cutting start point and the cutting end point. When the signs of R and U are inconsistent, it is required that | R│≤│U/2│, unit: mm;

F Metric thread pitch, value range 0＜F ≤500 mm, F code value is maintained after execution, input can be omitted;

I Inch thread number per inch, value range 0.06~25400 teeth/inch, The I code value is maintained after execution, and the input can be omitted;

J: The movement amount in the minor axis direction when the thread is withdrawn, the value range is 0~9999.999 (unit: mm), without direction (according to the program The starting point automatically determines the tail withdrawal direction), modal parameter, if the minor axis is the 0~9999.999 (unit: mm), without direction, modal parameter, if the long axis is the : 1～99, modal parameter.

(When L is omitted, the default is single-start thread)
