What does G0 mean in CNC machine What does G02 mean in CNC, be specific

CNC machine G00 for fast positioning.

G00 Quick Point Positioning:

Format: g00 x(u) z(w).

Description: (1) This command enables the tool to move quickly to the specified position according to the point control mode. The workpiece must not be machined during movement.

2) 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, and 3) the coordinates that do not move do not need to be programmed.

4) g00 can be written as g0

Example: G00 X75 Z200

g0 u-25 w-100

G0 indicates the function of this segment to achieve fast positioning.

z0 indicates that the x and z axes move to the specified position, depending on the current instruction mode, of course. If it is an incremental mode (G91), the X-axis moves in the positive direction, and the Z-axis does not move; In the case of absolute value (g90), the x-axis is moved to the position where the coordinate value is, and the z-axis is moved to the origin of the current coordinate system.

One look at your program to know that you are a dry CNC lathe, n0020 this is the serial number.

G0 is fast positioning.

Go is the quick positioning, and Z0 is the location you want to go.

If it is under normal circumstances, it should be, N0020 M03 S how much to see the car and what G0 Z0 F to see the car and what.

G02 is the arc interpolation instruction (clockwise rotation) in the CNC machining technical instruction.

CNC machining programming methods are divided into manual (manual) programming and automatic programming. Manual programming, the entire content of the program is written by manual according to the instruction format specified by the CNC system. Automatic programming, that is, computer programming, can be divided into automatic programming methods based on language and drawing.

However, regardless of the automated programming method, it requires the appropriate hardware and software.

It can be seen that the realization of CNC machining programming is the key. But programming alone is not enough, CNC machining also includes a series of preparations that must be done before programming and aftercare after programming.

Development Background

The initial idea of CNC machine tools, in 1952, the Massachusetts Institute of Technology developed a three-coordinate CNC milling machine. In the mid-50s, such CNC milling machines were used to process aircraft parts. In the 60s, CNC systems and programming work became more and more mature and perfect, CNC machine tools have been used in various industrial sectors, but the aerospace industry has always been the largest user of CNC machine tools.

Some large aviation factories are equipped with hundreds of CNC machine tools, among which cutting machine tools are the mainstay. CNC machined parts include the overall wall panel, girder, skin, bulkhead, propeller of aircraft and rocket, as well as the mold cavity of the casing, shaft, disc and blade of the aero engine and the special cavity surface of the combustion chamber of the liquid rocket engine. In the early stage of the development of CNC machine tools, it was mainly CNC machine tools with continuous trajectory and continuous trajectory control.

Circular command, clockwise machining.

G01 is a linear interpolation instruction in CNC machining technical instructions. The function of the linear interpolation command is that the tool starts from a certain point at the feed rate set in the program and moves in a straight line to the target point.

In this mode, the tool moves from one position to another with the shortest distance between the two endpoints, which is a very important programming function and is mainly used in contouring and forming machining. Any diagonal movements (e.g. chamfers, bevels, corners, cones, etc.) must be programmed in this mode for precise machining.

Rules and formats for use:

g01 x(u) z(w) f (linear interpolation moves from the current position to the command position in a straight line and at a command-given movement rate).

x and z are the absolute coordinates of the position to be moved;

U and W are the incremental coordinate values of the position to be moved;

f is the feed rate of the tool.

1. The G01 instruction is used when the tool processes the linear trajectory, such as the outer circle of the car, the section, the inner hole, the grooving, etc.

2.When the machine tool executes the linear interpolation instruction, there must be an F instruction in the program segment. The speed of the tool movement is determined by the magnitude of the value after f.

3. G01 and F are both modal instructions, the previous paragraph has been specified, and the following program segments can no longer be rewritten, just write out the moving coordinate value.

CNC machine tool standard g**.

The preparation function word is an instruction that enables the CNC machine tool to establish a certain processing method, such as interpolation, tool compensation, fixed cycle, etc. The G function word is composed of the address character g and the next two digits, with a total of 100 functions from g00 to g99. The JB3208-83 standard is specified in the following table:

Linear interpolation is linear cutting.

1. G00 is the speed positioning instruction of the fast draft, which moves to the positioning point according to the speed of rapid movement. G01 is a linear interpolation instruction that requires the specified speed of the F instruction to the specified position.

2. G00 does not have chamfering function; The G01 chamfer control function allows you to insert a straight chamfer or arc chamfer between the program segments of two adjacent trajectories.

3. G00 does not need the feed rate function F; When the G01 machine performs a linear interpolation command, there must be an F instruction in the program segment.

Summary. Pro-<>

Hello! 【Answer】G02 (clockwise arc interpolation) means that its path is clockwise; When identifying, it is necessary to use the tool holder of the machine tool as the rear tool holder (the tool holder is located opposite the operator); G03 (counterclockwise circular interpolation) means that its path is counterclockwise; Circular sowing is its definition; G01 (straight line replacement), but there is a difference between processing straight line and arc; However, the biggest difference between G01 and G02G03 is that G02G03 needs to be compensated for the tip radius when machining;

G00 is the indication that the machine tool is quickly located to the target point xyz without cutting the product

G01 refers to the cutting (machining) instruction of the machine head on the product, and the speed is specified by F.

f indicates how many millimeters per minute the product is fed.

Example: Ashisan. It means that the distance of the machine tool in the cutting diavel is 100 mm per minute.

G00 and G01 are two common commands in CNC systems to control machine tools for linear interpolation motion.

G00 is a quick positioning instruction, which is used to quickly move the tool or workpiece from the current position to the fixed position of the finger fiber, and its cover is characterized by moving at maximum speed, regardless of the smoothness and accuracy on the motion path, and is mainly used to quickly locate the position that is not processed.

G01 is a linear interpolation instruction for linear interpolation of a tool or workpiece at a specified speed and path. The G01 command takes into account the smoothness and precision of the tool or workpiece, allowing for precise machining path control. The G01 command generally needs to specify parameters such as the target position, movement speed, and compensation value of the imputed branch.

Therefore, the G00 is used for fast positioning, while the G01 is used for precise linear interpolation movements.
