What does G00 G01 G02 mean?

G00 is a fast point positioning, the tool does not process the workpiece, that is, it is positioned to the position of the workpiece to start processing; G01 is a straight line interpolation, the tool has begun to process, can be used to process the outer circle, inner hole and other straight parts; G02 is arc interpolation, and G03 is the same arc interpolation, the difference is that G02 is clockwise arc interpolation, and G03 is counterclockwise arc interpolation, that is, the arc direction is different, the selection instructions are also different, are used to process the part of the workpiece with arcs!

GO refers to approaching the workpiece quickly without touching it. g1 is a linear imputation. g2 is circular interpolation. They use some formats to specify spatial coordinates to control the trajectory of the tip of the knife!

A CNC was recently discovered**.

CNC net, I hope it will help you.

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

Command format: g01 x(u) z(w) f;

Where: 1, x, z or u, w have the same meaning as g00.

2. F is the feed speed (feed) of the tool, which should be determined according to the cutting requirements.

g02x（u）__z（w）__i__k__f__

or g02x(u) z(w) r f

Note: x and z are the absolute coordinate values of the end point of the arc;

U and W are the incremental cavity coordinates of the end point of the arc relative to the starting point;

i and k are the incremental coordinates of the center of the arc relative to the starting point;

r is the radius of the arc, when the central angle of the circle from the beginning to the end of the arc is less than or equal to 180 degrees, r is a positive value; When the central angle of the circle is greater than 180 degrees, r is negative. Because when CNC lathes process spherical surfaces, the central angle of the circle from the starting point to the end point is always less than 180 degrees, so r is generally a positive value.

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.

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.

The usage format of the NC programming instruction g81g82g83 is as follows:

1. First of all, when machining the workpiece hole, it can be divided into four planes according to the movement position of the tool, the initial plane, the R plane, the workpiece plane and the bottom plane of the hole.

2. The format of the central drilling cycle instruction G81 "G81 x y z r f This instruction is used for the fixed cycle of general hole drilling processing.

3. The drilling of G81 and G01 is actually similar, and the usage format of G81G82G83 is similar to that of each other.

4. When processing a deep hole with a length-diameter ratio (that is, the ratio of hole depth l to hole diameter d) greater than 5 10, the hole is semi-closed, and its derivation problem is chip breaking, chip removal is difficult, poor thermal conductivity, cooling and lubrication are not easy, and there will be poor tool rigidity, easy shaking, vibration, deformation and breakage.

This requires the selection of drilling process parameters, and the use of deep hole drilling cycle instructions: G73, G83 two instructions.

5. Different CNC systems, even if the same function of the drilling dust processing cycle, the instruction format has certain differences, therefore, the programming manual is mainly used when programming, so as to master the usage format of g81g82g83.
