End face grooving compound fixed cycle Okuma Control

G74 End face grooving compound fixed cycle

[Command format]

          G74 X_ Z_ I_ I_ K_ D_ L_ F_ E_ T_

  

         X: X coordinates of target point

          Z: Z coordinates of target point

          I: Shift distance in X-axis direction (Diameter instruction.  If not instructed, it is regarded as 0.)

          K: Shift distance in Z-axis direction (If not instructed, it is regarded as 0.)

          D: Cut depth

          L: Cut depth at removing the tool

          DA: Instruct a return distance.  If DA is not instructed,   it is regarded as the return distance set to that of the grooving, drill cycle (other function 1) of the optional   parameter.

          E: Dwell upon arrival at Z-axis target point (The unit of instruction is the same as G04.)   (If not instructed, this sequence will not be executed.)

          T: Tool compensation No. instruction which determines the tool compensation amount at Z-axis target point positioning (if not instructed, the T instruction at the start point positioning is used.  The T instruction next to this block, or the compensation number, acts as the T instruction at start point positioning.)

Face Grooving Cycle G74 Or Longitudinal Cut-Off Cycle

Face Grooving Cycle G74 Or Longitudinal Cut-Off Cycle

Overview:-

            This function is used for smooth disposal of machining ships in longitudinal cut-off machining. For SS materials which produce hard-to-cut machining chips this function can be managed for easy machining chip disposal. You can use this cycle for drilling

Programming Format:-

            G74 R__;

         G74 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 Movement Distance

          Q       =        Z-axis cut depth

R        =        ( 2^nd R )Tool Escape Distance at the Bottom of Cut

          F        =        Feed Rate

          S        =        S Command

          T        =        T Command

Drilling Cycle :-

            

         For drilling X, P and R (2^nd ) are  not required .Omit these dada.

Notes:-

1.   During single block operation, all the blocks are executed step by step2.   Omission of address X , P and R( 2^nd ) provides the operation of Z axis alone , resulting in peck drilling cycle.3.   R ( 1^st ) and R ( 2^nd ) are both command values address R. the differentiation is given by whether Z is commanded together . that is ,the command R together with Z results in the flat of R ( 2^nd )4.   Cycle operation is performed in the block where Z is commanded
