How to use the G17G18G19 in the FANUC CNC milling machine

g17, g18, g19 are plane selection commands that can be used to select planes.

G17: Select the XY plane.

G18: Select the Zx plane.

G19-Y is the selection plane.

The Plane Selection G17, G18, G19 directives are used to specify the interpolation plane and the tool radius compensation plane for the cutter in the program segment. Indicates the function that the machining takes place in a certain plane. G17—in XY, G18—in ZX, G19—in YZ, the writing of the coordinate address character in the program segment should be consistent with the plane instruction.

g17g18g19 in other commands: For example, the program to apply the rotation command is:

N10 G92 X-5 Y-5 establishes the machining coordinate system shown in the figure.

N20 G68 G90 X7 Y3 R60 starts with the point (7,3) as the center of rotation and rotates 60° counterclockwise.

N30 G90 G01 X0 Y0 F200 describes the motion according to the original machining coordinate system, reaching point (0,0).

g91 x5 y5) If you run the program segment in parentheses, the current point of (-5, -5) will be rotated 60° as the center of rotation

N40 G91 x10 x to (10,0).

N50 G02 Y10 R10 Feed in a circle.

N60 G03 X-10 I-5 J-5 Reverse Circular Feed.

N70 G01 Y-10 returns to point (0,0).

N80 G69 G90 X-5 Y-5 Undo the rotation function and return to (-5, -5) points.

G17, G18, and G19 are plane selection commands that can be used to select planes.

Command description: 1) G17 indicates the selection of XY plane;

2) G18 indicates the selection of the ZX plane;

3) G19 indicates that the YZ plane is selected. For CMM milling machines and machining centers (zhongxin), these commands are commonly used to determine in which plane the machine is interpolated.

G17, G18, and G19 are plane selection commands that can be used to select planes.

G17: Select the XY plane. G18: Select the Zx plane. G19-YZ: Select a plane.

The Plane Selection G17, G18, and G19 commands are used to specify the interpolation plane and the tool radius compensation plane of the cutter in the program segment, respectively.

Select the coordinate system, G17-XY plane, G18-XZ plane, G19-YZ plane.

For G00 and G01, these commands are invalid and have no effect.

Valid only for G02, G03, e.g., G18 G01 X30 Z0 F1000

G18 G02 X30 Z0 I-30 K0 F500 represents a full circle in the Xz plane, starting from X30Y0 in a clockwise direction (from the positive direction to the negative direction of the Y axis).

The most difficult thing to understand here is the direction of discrimination, remember that it must be (from the positive direction to the negative direction).

Coordinate system conversion, processing different planes are used, and the program can be used with one (special case).

G16 is the beginning of the use of polar coordinates, and G15 is the end of the polar coordinates.

For example, there are two ways to make three holes in the size shown below.

First method:

g54 g90 g80 g00 g43 h1 z100;

x0 y0 m03 s600;

g16 g00 z10 m08;(Start Polar Coordinates).

g98 g81 x50 y30 z-20 r3 f50;(x50 for the radius, y30 for the angle).

y150;(The position of the second hole is at 150 degrees).

y270;(The position of the second hole is at 270 degrees).

g15 g80 g00 z100 m09;(End Polar).

m05;m30;

The second method, g91 can also be used in the program, which is more convenient.

g54 g90 g80 g00 g43 h1 z100;

x0 y0 m03 s600;

g16 g00 z10 m08;(Start Polar Coordinates).

g98 g81 x50 y30 z-20 r3 f50;(x50 for the radius, y30 for the angle).

g91 y120;(With g91, this point is moved 120 degrees relative to the previous point).

y120;g15 g90 g80 g00 z100 m09;(End Polar and End Relative Coordinates).

G16 is the flexible selection of the processing plane, and G17, G18, G19 are selected according to the coordinates.

G17 is the XY plane.

G18 is the zx plane.

g19 is the yz plane.

For example, G92 G17 x y has j k For example, G16 is polar coordinate programming, after using G16, x represents the programming radius and Y represents the angle, which is processed in a circle. As.

g0g90g16g54x100y45.The machine tool goes to the center of the circle with G54X0Y0. The angle of the radius of 100 to 45 went there.

Then run the subroutine M98 or run the drill hole **G83 G81, etc.

You wrote it wrong without g15

It's G16, G17, G18, G19

Among them, G16 is a flexible selection of the processing plane, which generally refers to the application of the Siemens 840C system, and the G17, G18, G19 basically machining centers should follow the right-hand Cartesian coordinate system criteria to select the processing plane.

G17 is the XY plane.

G18 is the zx plane.

g19 is the yz plane.

G16 is the flexible selection processing plane, G17, G18, G19 are selected according to your coordinates.

G17 is the XY plane.

G18 is the zx plane.

g19 is the yz plane.

For example, g92 g17 x y has j k

The one in front of me gave the g** table of the lathe, not the milling machine. If you need to give us an email address, I wrote a programming manual for a machining center (FANUC-0MC) 10 years ago for your reference.

This is the preparation instruction made by the program setter before the program runs, such as G21 is to require the machine tool to perform the metric system on the program data, so as to prevent others from returning to the metric system after using the imperial system. G17 is to tell the system which plane I need to cut, G40 is to cancel the tool radius compensation to ensure that the tool runs at the position set by the program, and G98 is a fixed cycle return. G80 cancels the loop, and G54 represents the coordinate system of the workpiece that will be executed.

……These commands in the header of the program only need to set the environment for the following program to run. If it weren't for these environments, the system would execute these commands, causing the machine to change to a commanded state. The program runs without fail.

The meaning of the directive is:

1. When your program needs to walk the g02 g03 arc on the x y plane, you should define g17 in advance.

2. When your program needs to walk the g02 g03 arc on the x z plane, you should define g18 in advance.

3. When your program needs to walk the g02 g03 arc on the y z plane, you should define g19 in advance.

G** is an instruction in a numerical control program, which is generally called a g-instruction. The use of g** can realize fast positioning, reverse circle interpolation, forward circle interpolation, intermediate point arc interpolation, radius programming, and jump processing.

When your program needs to walk the g02 g03 arc in the x-y plane, you should define g17 in advance

When your program needs to walk the G02 G03 arc in the X Z plane, you should define G18 in advance, and pay attention to the difference between the rotation direction of G02 and G03 when the Y-axis is in the positive direction or the Y-axis secondary direction.

When your program needs to walk the G02 G03 arc in the Y Z plane, you should define G19 in advance, and pay attention to the difference between the rotation direction of G02 and G03 when the Y-axis is in the positive direction or the Y-axis secondary direction.
