G02 Circular interpolation-CW okuma CNC Program

G02 Circular interpolation (CW)

      It Moves from the current position to the target position at the instructed radius and feedrate in circular path.

[Command format]

          G02 X___ Z___     (I___ K___) F___

          (L___         )

          G02 X___ Y___     (I___ J___) F___  (Y-axis control)

          (L___        )

          G02 Y___ Z___     (J___ K___) F___  (Y-axis control)

          (L___        )

I: Signed distance from the starting point to center of circle in the X-axis direction.

K: Signed distance from the starting point to center of circle in the Z-axis direction.

J: Signed distance from the starting point to center of circle in the Y-axis direction.

L: Radius of circular path

F: Feedrate

[Note]

          1. I and K commands instruct the radius.

          2. While two arcs can be obtained from the L command, the 180 or less arc is selected.  To select an arc having more than 180, instruct CALRG at the same time

          3. The Y axis control is the special specification.

Radius designated circular interpolation commands G02, G03:-

                   Circular interpolation can be performed by designating directly the arc radius R as well as using conventional arc center coordinates (I, J, K)

 Program format:-

                   G02 (G03) X__ Y__ Z__ R__ F__

          X : X axis coordinates of the end point

          Z : Z axis coordinates Of the end point

          Y : Y axis coordinates of the end point

          R : Radius of the arc

          F : Feed rate

Example:-

          G02 X100.0 Z50.0 R50.0 F10. ;

Detail:-

          A semi –circle Or smaller will be generated if R is a positive Value.

          An arc larger than the Semi-circle will be generated if R is a negative value.

G02 Circular interpolation CW , G03 -CCW Program Method

G02 Circular interpolation CW:-

The command below will move a tool along a circular arc.( CW )

Description:-

          Once the G02 or G03 command has been given, this command mode will be retained until any other G-code command used to override the G02 or G03 command mode, that is , G00 or G01 of command given .

The direction of circular movement is determined by G02 / G03

G02:   CW (clockwise)

G03:   CCW (counterclockwise)

Program Format:-

               

G02 or G03 X___ Y___ Z__         I___ J___ K___ F___

X : Arc ending point coordinates , X axis ( absolute value )

Z : Arc ending point coordinates , Z Axis ( absolute value )

Y : Arc ending point Coordinates , Y Axis ( absolute value )

I : Arc Center , X axis ( radius command , incremental value of start point )

K : Arc center , Z axis ( incremental value of start point )

J : Arc center , Y axis ( incremental value of start point )

F : Feed Rate

Rotational direction

                   CW (G02) or CCW (G03)

Arc ending point coordinates

                   Given with address X, Z, Y, U, W, V.

Arc center coordinates

                   Given with address I, J, K (incremental dimension)

Feed rate

                   Given with address F.

Example:-

          G02 X120.0 Z70.0 I50.0 F200.0 ; ( absolute data setting )

          G02 U100.0 W-50.0 I50.0 F200.0 ; ( incremental data setting )

Notes:-

          G02 or G03 during circular interpolation refers to the rotational direction in the right handed coordinates system when seen from the plus side toward the minus side of the coordinate axis perpendicular to the plane to be interpolated.

          If the coordinates of the ending point are not set or if the starting and ending points are set at the same position, designating the center using address I, K or J will result in an arc of 360 degrees ( true circle )
