Transverse Cut-Off Cycle G75 Or Diameter Grooving Cycle:-



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
