G 76 Threading Canned Cycle

Format For G 76 Threading Canned Cycle :-

The G76 command contains, within two blocks, all the information required to generate a standard thread form and pitch
A G76 uses one edge cutting to reduce the load on the tool tip

Format :-

G76 P (A) / (B) / (C) _ _ _ _ _ _Q _ _R _ _;
G76 X _ _Z _ _P _ _Q _ _F _ _;

In First Block:-

where,
P (A) is the number of thread finishing passes (1 to 99)
P (B) is the chamfer amount. This is the angle at which the tool leaves at the end of the thread cutting cycle
P (C) is the angle of the tool tip (80°, 60°, 55°, 30°, 29° and 0°)
Note - (A), (B) and (C) are all specified at the same time by the address P,
Ex, P030060 = number of cuts is 03, chamfer amount of 00 and tool angle of 60°
Q is the minimum cutting depth (in microns
R is the finishing allowances

In Second Block:-

X is the end position of the thread in the X axis (the minor diameter)
Z is the end position of the thread in the Z axis
P is the depth of the thread as a radius value (in microns)
Q is the depth of the first pass as a radius value (in microns)
F is the size of the thread Pitch

G 76 is a Threading Canned Cycle which is use for Cutting Threading for Outer Diameter & Inner Diameter
