Supplement: CNC is the abbreviation of digital control, CNC technology is a method of using digital information to control mechanical movement and machining process.

- y-z - Mirror command.

It's also a mirror image but it can only be an axis.

G51 can be a point or axis mirror.

In this way, the XYZ on that is a little KS to you.

G54 and G55 all represent a coordinate system, they can be the same or different, depending on how you set the tool.

G54 G59 is the instruction to set the processing BAI coordinate system, and DUG54 corresponds to the No. 1 workpiece coordinate system ZHI. Determination of the processing coordinate system DAO:

The machining coordinate system refers to the coordinate system established based on the determined machining origin. The machining origin, also known as the program origin, refers to the position of the corresponding programming origin in the machine tool coordinate system after the part is clamped.

In the machining process, the CNC machine tool is processed in accordance with the machining origin position and program requirements determined after the workpiece is clamped. When programming the program, the programmer can select the programming origin, establish the programming coordinate system, and calculate the coordinate value according to the part drawing, without considering the actual position of the workpiece blank clamping.

For the processing personnel, the programming origin should be converted into the machining origin when clamping the workpiece and debugging the program, and the position of the machining origin is determined, and the setting is given in the numerical control system (that is, the origin setting value is given), and the coordinate value of the starting point of the tool can be determined according to the current position of the tool after the machining coordinate system is set.

During machining, the coordinate values of each size of the workpiece are relative to the machining origin, so that the CNC machine tool can start processing according to the accurate machining coordinate system position.

Summary. 1 Fast point move g00

Format: g00x(u) z(w) ;

where x(u) and z(w) are the coordinate values of the target point.

2 Linear interpolation G01

Format: G01 x(u) z(w) f;

where x(u) and z(w) are the coordinates of the target point, and f is the feed rate.

When the machine executes the G01 command, if there is no F instruction in the previous program segment, the F instruction must be included in the program segment. G01 and F are both modal instructions.

The CNC lathe G54 and G55 are programmed together to set the tool.

Hello, the tool should be set according to the situation that there is no origin offset, if the tool is set according to the origin after the offset, after the tool is aligned, the adjustment value should be entered.

Hello: How to program G54 and G55 for processing two workpieces with Guangzhou CNC lathe?

What is an adjustment value.

You can send the tool directly in the G55 or G54 coordinate system, and you can call it if the program is G55.

Pair the tool to the first workpiece, with G54What about the second artifact?

G59 How to program G59 coordinates.

1 G00 format for quick point movement: g00x(u) z(w); where x(u) and z(w) are the coordinate values of the target point. 2 Linear interpolation G01 format:

g01 x(u)_z(w)_ f_；where x(u) and z(w) are the coordinates of the target point, and f is the feed rate. When the machine executes the G01 command, if there is no F instruction in the previous program segment, the F instruction must be included in the program segment. G01 and F are both modal instructions. Thank you.

G54-G59 are the coordinate system zero offset commands.

G50: Coordinate axis setting (actually: according to the actual position of the tool, determine the x, z coordinate values of the workpiece coordinate system).

After the G50 command is executed, no motion is generated, but the workpiece coordinate system is updated according to the command value.

Examples: G50 X100 Z250;

Its essence is that the X coordinate of the workpiece coordinate system is immediately modified to 100, and the Z coordinate is modified to 250, and the system immediately displays the new coordinate value, and one share is used to establish the workpiece coordinate system through the tool in the input mode.

The meaning of different CNC systems G50 is different. In the funac system CNC lathe, it represents the establishment of a workpiece coordinate system.

CNC milling and machining centers represent unscaling.

CNC machining center?

G50 scale is canceled.

In the case of a lathe, the coordinates of the workpiece are set.

The meaning of the same CNC system G50 is different.

In the funac system CNC lathe, it represents the establishment of a workpiece coordinate system.

CNC milling and machining centers represent unscaling.

Zhang Pianwei was in a daze of rage.

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).

m05;m30;

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

This program is full of errors! First of all, your G72 instruction is completely wrong, the second is the question you have to ask, G50, he has two meanings, one is the maximum speed limit, the other is to establish a new coordinate system, is the coordinate system, it should be said that the coordinate system is offset, not the origin, generally used in M98 subroutines are more extensive and convenient.

The meaning of this g50 is actually to establish the workpiece coordinate system, g50x80 z20 is to establish the workpiece coordinate system, and the knife stops at the place of x80 and z20. The position of the tool minus 20 is the zero point, that is, the center of the right end face of the workpiece is the origin. I don't know if I can understand it?

In fact, you can check the G50 method for setting up the workpiece coordinate system. There is a lot of information on the Internet.

The G50 has two different functions in different systems.

In more cases, in constant line speed programming, the maximum speed of the spindle is limited by G50.

There are also some systems that use G50 to set up the workpiece coordinate system, similar to the G92 workpiece coordinate system in the old system.

G50S1200 sets the maximum number of spindle revolutions.

G50 IP -- Set the coordinate system.

Two functions in the same system.

There are two meanings: 1Set the maximum speed of the spindle, such as G50S2500; 2.Used to set the coordinate system or move the coordinates.
