In the machining center, **g10 is the coordinate where the value is written. The G10 allows the user to set the offset in the program, and use the G10 instead of manually entering the tool length offset, radius compensation, workpiece coordinate system offset, etc.

g10l_p_r_x_y_z_

l: the selected offset type, the origin of the workpiece coordinates of L2G52 and G54-G59; L10 tool geometry page and length offset (h**); L11 cutter wear page length offset (h**); L12 tool geometry page and radius compensation (d**); L13 tool wear page and radius compensation (d**); L20 G110-G129 auxiliary workpiece coordinate origin.

P: The special bias of the choice, since P is the option that follows L, the meaning of P is different in different L types.

g101=Mirroring is turned on. When the program in the m198 call card uses this command, you must use cf to operate it on the phone. The M98 call subroutine refers to the program that is used in the machine.

The shape of the machined surface of a milling machine is generally composed of straight lines, arcs or other curves. And hail the ordinary milling machine operator according to the requirements of the drawing. Continuously changing the relative position between the tool and the workpiece, and then matching with the selected milling cutter speed, the tool can cut the workpiece, and a variety of different shapes of workpieces can be processed.

CNC machining is to divide the motion coordinates of the tool and the workpiece into the smallest unit quantity, that is, the minimum displacement. According to the requirements of the workpiece program, the numerical control system makes each coordinate move several minimum displacements, so as to realize the relative movement of the tool and the workpiece to complete the processing of the part.

1. Fast positioning: G00 x(u) z(w).

Note: This command enables the tool to quickly move to the specified position according to the point control mode. The workpiece shall not be processed during the movement; All programmed axes move at the same time at the speed defined by the parameters, and when one axis finishes the programmed value, it stops while the other axes continue to move; Coordinates that do not move do not need to be programmed; g00 can be written as g0.

Examples: G00 X75 Z200, G01 U-25 W-100. First, X and Z go 25 at the same time to get to point A, and then Z goes 75 to point B.

2. G01 - linear interpolation: G01X(U) Z(W) F (mm min).

Description: This command moves the tool to the specified position in a linear interpolation pattern. The movement speed is the feed rate commanded by f. All coordinates can be linked; g01 can also be written as g1.

For example: G01 X40 Z20 F150, two axes are synchronized from point A to point B.

3. Inverse circular interpolation: g02x(u) z(w) i k f

Note: When X and Z are at G90, the coordinates of the end point of the arc are the absolute coordinate values relative to the programmed zero point. At g91, the end of the arc is an incremental value relative to the start of the arc.

Regardless of g90 or g91, i and k are the incremental coordinates of the center of the arc relative to the starting point. i is the value in the x direction and k is the value in the z direction. The center coordinates of the circle shall not be omitted in arc interpolation, unless programmed in another format; When the G02 instruction is programmed, it can be directly programmed through the quadrant.

circles, circles, etc.; g02 can also be written as g2.

Example: G02 X60 Z50 i40 K0 F120

4. Interpolation along the circle, except that the arc rotation waxing elimination direction is opposite, the format is the same as the G02 instruction.

5. G04—Timed Pause: G04 F or G04 K

Note: The processing movement is paused, and the processing is resumed when the time is up. The pause time is specified by the data following f. The unit is seconds. The range is from seconds to 300 seconds.

6. Intermediate point arc interpolation: g05x(u) z(w) ix iz f

Note: x,z are the coordinates of the end point, and ix and iz are the coordinates of the intermediate point. Others are similar to G02 G03.

Example: G05 X60 Z50 ix50 iz60f120

7. Acceleration and deceleration: G08

Note: They occupy a single line in the program segment, and the feed rate will increase by 10% when running to this segment in the program, and 20% increase will need to be written as two separate segments.

8. Radius programming: G22

Note: If you occupy a single line in the program, the system runs in radius mode, and the following values in the program are also based on the radius.

9. G23 (G230) - diameter size programming mode: G23

Note: If you occupy a single line in the program, the system will run in diameter, and the following values in the program will also be based on the diameter.

G** is a standard language used to control the movement of machine tools, which can be used to program in CNC machining centers to control the operation of machine tools.

G** is an alphabetic code starting with g, which is a command composed of a set of letters and numbers, which can move the machine to a pre-set coordinate position.

The G** consists of a series of precisely defined program instructions that can be used to control machine movement, feed characteristics, tool selection, workpiece alignment, and non-mechanical behavior, such as material airflow cleaning.

The actual operation of G** requires loading the program to the CNC machine tool and passing the program to the machine tool controller, so that it can complete the operation required in the instruction according to the G** program.

In addition, the motion servo controller can also be used to keep the machine in a pre-set high-precision position.

The development of G** can be done with the help of some CNC programming software and CAD CAM software to realize the program control of the machine tool.

Due to the accuracy of the action of the G** control machine tool and its widespread use, efficient and automated machining can be realized.
