Transverse Cut-Off Cycle G75 Or Diameter Grooving Cycle:-
Overview:-
This function is used for smooth disposal of machining chips in transverse cut-off machining. This allows easy disposal of machining chips in face turning as well. Both G74 and G75 which are used for cutting off, grooving or drilling, are a cycle to give the escape of a tool automatically. Four patterns which are symmetrical with each other are available. During single block operation, all the blocks are executed step by step.
Programming Format:-
G75 R (1st ) ;
G75 x__ Z__ P__ Q__ R__ F__ S__ T__ ;
Description:-
R = Distance of Return
X = Absolute Value / Incremental Value of X-Axis
Z = Absolute Value / Incremental Value of Z Axis
P = X-axis cut depth
Q = Z-Axis Movement Distance
R = ( 2nd R )Tool Escape Distance at the Bottom of Cut
F = Feed Rate
S = S Command
T = T Command
