G00—Quick positioning format: G00 The workpiece must not be processed during movement. (2) All programmed axes move at the speed defined by the parameters at the same time. When an axis reaches the programmed value, it stops, while other axes continue to move. (3) Coordinates that do not move do not need to be programmed. (4) G00 can be written as G0. Example: G00 G01—Linear interpolation Format: G01 The moving speed is determined by the F command feed speed. All coordinates can be run in conjunction. (2)G01 can also be written as G1. Example: G01 In G90, the arc end point coordinate is the absolute coordinate value relative to the programmed zero point. In G91, the arc end point is the incremental value relative to the arc starting point. Regardless of G90 or G91, I and K are the coordinate values ??of the arc end point. I is the X direction value and K is the Z direction value. The circle center coordinates cannot be omitted during arc interpolation unless programmed in other formats. (2) When programming the G02 instruction, you can directly program quadrant circles, full circles, etc. Note: When crossing the quadrant, gap compensation will be automatically performed. If the gap compensation input at the end of the parameter area is significantly different from the actual backlash of the machine tool, obvious cuts will be produced on the workpiece. (3) G02 can also be written as G2. Example: G02 X60 Z50 I40 K0 F120 Format 2: G02 radius. R is signed, "+" means the arc angle is less than 180 degrees; "-" means the arc angle is greater than 180 degrees. The "+" can be omitted. (3) It is based on the coordinates of the end point. When the length value between the end point and the starting point is greater than 2R, a straight line is used instead of the arc. Example: G02 X60 Z50 R20 F120 Format 3: G02 Same as format 2. G03—Circular interpolation description: Except that the arc rotation direction is opposite, the format is the same as the G02 command. G04—Timed pause Format: G04__F__ or G04 __K__ Description: The processing movement is paused. After the time is up, continue processing. The pause time is specified by the data following F.

G25—Jump processing Format: G25 LXXX Description: When the program is executed to this program, the program segment specified by it will be transferred. (XXX is the program segment number).

(3) Changes in the X value can process taper threads. (4) When using this command, the spindle speed cannot be too high, otherwise the tool wear will be greater.

G50—Set the workpiece coordinates/Set the maximum (low) spindle speed Format: G50 S____Q____ Description: S is the maximum spindle speed, Q is the spindle minimum speed G54—Set the workpiece coordinates Format: G54 Description: There can be several in the system There are two coordinate systems, G54 corresponds to the first coordinate system, and its origin position value is set in the machine tool parameters. G55—Set workpiece coordinates 2, same as above G56—Set workpiece coordinates 3, same as above G57—Set workpiece coordinates 4, same as above G58—Set workpiece coordinates 5, same as above G59—Set workpiece coordinates 6, same as above G60—Accurate path mode format: G60 Description: In the actual processing process, when several actions are connected together, and when programming with accurate paths, there will be a buffering process (that is, deceleration) when performing the next section of processing. G64—Continuous path mode Format: G64 Description: Relative For G60. Mainly used for rough machining. G74—Reference point return (machine zero point) Format: G74 X Z Description: (1) No other content may appear in this paragraph. (2) The coordinates appearing after G74 will return to zero in order of X and Z. (3) Before using G74, you must confirm that the machine tool is equipped with a reference point switch. (4) Single-axis zero return can also be performed. G75 - Return to the zero point of the programmed coordinates Format: G75 X Z Description: Return to the zero point of the programmed coordinates G76 - Return to the starting point of the programmed coordinates Format: G76 Description: Return to the position where the tool starts processing. G81—Outer circle (inner circle) fixed cycle Format: G81__X(U)__Z(W)__R__I__K__F__ Description: (1) X, Z are the end point coordinate values, U, W are the increment values ??of the end point relative to the current point. (2)R is the diameter of the starting section to be processed. (3) I is the rough turning feed, K is the finishing turning feed, I and K are signed numbers, and the signs of the two should be the same. The symbol convention is as follows: cutting from the outside to the central axis (turning the outer circle) is "—", and vice versa is "+". (4) Different X, Z, R determine different switches of the outer circle, such as: with taper or no degree, forward taper or reverse taper, left cutting or right cutting, etc. (5) F is the cutting speed (mm/min) (6) After the processing is completed, the tool stops at the end point. Example: G81 Two-axis interpolation, cutting to the end section, stopping if the processing is completed: 3: G01 retracts I to a safe position, and performs auxiliary section smoothing at the same time 4: G00 rapidly feeds to outside the high working plane I, leaving I for the next step For cutting operations, repeat to 1. G90—Absolute value mode programming Format: G90 Description: (1) When G90 is programmed, all coordinate values ??programmed in the future are based on the programmed zero point.

In the next segment of the coordinate system, the previous point is always used as the starting point for programming.
