How to use the fourth axis of the FANUC system in the machining center?

Usually g58 a-- a means the angle at which you want to rotate, rotate clockwise, positive and negative.

It seems that you can only use g0, g0a10; Try it, pay attention to the coordinate system, don't crash the handwheel!

The FANUC 0-M system quadcopter opens and closes the sail regiment with the following parameters:

1. After starting the machine first, first rotate the spindle once, such as: M3S500, and then execute M19 to see if the 445 parameters of the diagnosis change.

If the diagnostic parameter 445 is always 0, check whether the NC parameter 3117 1 is 1, as shown in the following figure.

2. Then after pressing the reset button, the diagnostic parameter 445 becomes 0, and check whether the NC parameter 4016 7 is 0.

3. Then after the spindle positioning is corrected, the value in the diagnostic parameter 445 is written into the NC parameter 4073 4077, and the spindle positioning can be set to complete.

4. Finally, when the spindle, the spindle motor, the spindle coder or the positioning deviation are replaced, the spindle positioning needs to be reset; The general setting method is as follows: after the spindle positioning is corrected, the value in the diagnostic parameter 445 is written into the NC parameter 4073 4077, as shown in the following figure.

The vertical x-axis of the rotation direction is called: a axis, and the command is a (the degree of rotation behind it, that is, the coordinate value) to make it rotate.

The vertical y-axis is called: the b axis, and the command is b, so that it rotates.

The vertical z-axis is called: the c-axis, and the command is c, so that it rotates.

1. If the brake is open and the Z-axis is moved, the load current will increase immediately. 2. If you judge whether it is Z, you can check the circle before the no-load test to see if the no-load load current is also very large. 3. When the servo is not prepared, manually rotate the motor to see if there is any stagnation and poor rotation (without holding the brake).

4. If there is a drive that can be reversed, or the motor is noisy. It is recommended to use the swap method to try to ascend and call down. 5. There is also the phase sequence of the three electrics, confirm it.

Have a great day! 6. There may be both drive and motor, and you have to judge it yourself.

k argument can be turned off.

1. Check the spindle amplifier and its communication line with NC (cable or optical cable and connector).

2. It is recommended to clean the MEM card, if it is invalid, you can try to replace the card.

3. Whether the environment in which the machine tool is used is too humid.

When the servo movement exceeds the allowable error range, the CNC system will generate an alarm of excessive position error, including following error, contour error and positioning error. The main reason: the tolerance range set by the system is too small

Improper servo gain setting; Contamination of the position detection device; The cumulative error of the feed drive chain is too large; The balancing device is unstable when the headstock moves vertically.

Fanuc MF system is a common numerical control system used to control machining centers and other machine tools for machining operations. If you want to add a fourth axis to a machining center, you need to set the following parameters and operate:1

Parameter setting (1) determines the type and model of the fourth axis, e.g. whether it is a turret or a turret. (2) Set the resolution of the fourth axis, that is, the number of pulses required for one revolution. (3) Set the maximum rotational speed and acceleration of the fourth axis.

4) Set the coordinate system of the fourth axis, e.g. g54-g59. (5) Determine the zero position of the fourth axis, and set the coordinate system offset and parameters. 2.

Operation method (1) Connect the fourth axis to the control system of the machine tool and make sure that the power and signal connections are correct. (2) In the parameter setting interface of the system, set the parameters of the fourth axis. (3) Add the relevant instructions of the fourth axis to the program of the machining center, such as the axial command (A axis or B axis) in the G generation Sakura code.

4) In the operation interface of the machining center, select the fourth axis, and manually debug to check whether the rotation of the fourth axis is correct. (5) In the CAM software of the machining center, program and add the relevant instructions of the fourth axis. It should be noted that adding the fourth axis requires some experience in machine operation and programming, if you are unsure of the operation method or parameter settings, please consult the machine tool manufacturer or technical support personnel to help Lu Lasuke.

At the same time, during the operation, it is important to ensure safety and operate in accordance with the operating procedures.

Summary. Glad for your question, here is my answer: Before opening the fourth axis with the Fanuc MF system, the following parameters need to be set:

1.Parameters 3221 and 3222: set the resolution and maximum rotation speed of the fourth axis respectively; 2.

Parameter 3223 3226: set the offset value, offset direction, rotation direction and rotation angle of the fourth axis respectively; 3.Parameter 3227 3228:

Set the zero position of the fourth axis and the direction of pulse counting respectively. After the settings are complete, perform the following operations:1

The fourth axis is mounted on the machining center and connected to the MF system; 2.In the "System Parameters" of the MF system, find the "Fourth Axis Setting" option, and enter the values of the above set parameters; 3.The relevant programs are programmed in the machining center, and the fourth axis is used for machining or positioning operations.

I'm glad to ask you a question, and here is my answer: Before using the FANUC MF system machining center to open the fourth axis, you need to set the following parameters:1

After the setting is completed, Wu Jian needs to perform the following operations:1The fourth axis is mounted on the machining center and connected to the MF system; 2.

In the "System Parameters" of the MF system, find the "Fourth Axis Setting" option, and enter the values of the above set parameters; 3.The relevant programs are written in the Naixian machining center, and the fourth axis is used for machining or positioning operations.

Excuse me, but please go into more detail?

Okay, let me add my answer: it should be noted that when setting up and operating the fourth shaft, it needs to be carried out according to the requirements of the MF system, and it is necessary to ensure that the transmission system and electrical system of the fourth shaft are working properly. In addition, it is also necessary to pay attention to safety in the operation process of socks to prevent accidental injuries to the hair mask.

There are many ways to realize the spindle positioning, and there are the following kinds according to the different control methods

1) Mechanical deceleration positioning: The spindle is mechanically decelerated and positioned, which is called mechanical deceleration positioning.

2) Electrical deceleration positioning: The electrical deceleration and positioning of the spindle are called electrical deceleration positioning.

3) Magnetic induction positioning of electrical deceleration: the spindle is decelerated by electrical appliances and positioned by magnetic induction.

4) Mechanical positioning of electrical deceleration: the spindle is electrically decelerated and the positioning is completed by machinery.

5) Hydraulic (or pneumatic) positioning.
