Does the FANUC machining center need to be supported by the tool change macro?

This is needed.

In the automatic tool changer of CNC machine tools, the device that realizes the transfer between the tool magazine and the machine tool spindle and the loading and unloading tool is called the tool exchange device.

1) No manipulator tool change. The used tool must first be returned to the magazine and then a new tool must be removed from the magazine, which cannot be done at the same time, so the tool change time is long.

2) Manipulator tool change. The tool change method with a robot (shown in the figure) is the most widely used, due to the flexibility of the robot tool change and the reduction of tool change time.

CNC milling machine is an automatic processing equipment developed on the basis of general milling machine, the processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

The tool change point is the Z-axis tool change position coordinates of the tool changer machine, and the parameter is 1240. Run "G90G, 30Z0" to the position of the tool change point, M6T is the tool change coordinates, and enter the specific value.

The FANUC system is a common CNC machine program in the CNC machine shop, and its operation panel is simple and easy to understand. Fanuc company was founded in Japan in 1956, the Chinese name Fanuc (also translated into Franco), is the world's CNC system scientific research, design, manufacturing, sales strength of the enterprise, currently has 4549 employees.

The connection of the servo is divided into type A and type B, which is controlled by a short rod on the servo amplifier. The Type A connection is to connect the position feedback line to the CNC system, and the Type B connection is to connect it to the servo amplifier. Type B for 0i and recently developed systems.

oMost systems use type A. The two connection methods cannot be used arbitrarily, and it is related to the servo software.

When connecting, the final amplifier JXLB needs to be plugged into the FANUC (the provided short plug, if forgotten, a 401 alarm will appear. In addition, it is recommended to use a servo amplifier to control two motors, and the large motor should be connected to the M terminal, and the small motor should be connected to the L terminal, otherwise the motor will hear an abnormal humming sound when it is running.

The tool change point is the Z-axis tool change position coordinates of the tool changer machine. The parameter is 1241, which means the coordinate value of the second reference point in the mechanical coordinate system.

The G90G30Z0 runs to the tool change point, and the M6T is a tool change.

Judging by your introduction, you should actually be talking about the position of the knife, not the point of changing the knife. There is only one tool change point, which has nothing to do with the operation. You need to use the knife to make up, the tool length to correct, the specific content take a good look at the fanuc operation book, there are all on it.

The tool change point is fixed. If you change it, you will lose the knife! The other thing is that you're not afraid of hitting knives. You don't need x and y to change knives.

If you use multiple coordinate systems, set the zero position of the workpiece to the corresponding coordinate system, and then specify one to do one.

It is to the reference point of tool change, g91g30x0y0z0; t1m6

Broach clamping signal proximity switch.

Unstable, adjust the position to fix this problem.

1 In MDI mode, press the SET button and enter 1 on the screen to turn on the parameter switch.

2 Press the "Password" button at the bottom of the screen to enter the password interface. Enter "admln" and press the "OK" button.

3 Press the "Programmable" button, and then press the corresponding "PLCPAR" button at the bottom of the screen to enter the K-parameter screen. Note that now to change the k-parameter, take a picture of the screen and save it. In case you make a mistake.

4 Move the cursor, change K10 7 and K10 6 to "1" respectively, and press "Save". Note that pressing the up and down keys moves the cursor as a whole into a row. Press the left and right buttons to select K10 7 and K10 6 and enter "1".

5.Press the "MDI" key, then press the "Programm" button to return to the K parameter screen, change and modify back to "0", and then press the "Save" button to save. The machine is stopped for commissioning. Turn off the parameter switch, and you're ready to change tools.

Summary: The tool change point is the Z-axis tool change position coordinates of the tool magazine machine, and the parameter is 1240. Pay attention to modify the system parameters, it is best to take pictures and record the data before the modification, after all, these parameters are set by the manufacturer, do not move before you figure it out.

FANUC is a Japanese company specializing in CNC systems, founded in 1956. It is the world's largest manufacturer of professional CNC systems, accounting for 70% of the global market share. FANUC first introduced the electro-hydraulic stepper motor in 1959, and gradually developed and perfected the hardware-based open-loop CNC system in the following years.

Since the advent of FANUC in 1974, FANUC has been committed to the leading and innovative technology of robotics, and is the only company in the world that makes robots by robots, the only robot company in the world that provides integrated vision systems, and the only company in the world that provides both intelligent robots and intelligent machines.

With up to 240 kinds of FANUC robot product series, with loads ranging from kilograms to tons, they are widely used in different production links such as assembly, handling, welding, casting, spraying, and palletizing to meet the different needs of customers.

FANUC tool change program recovery: This is a problem that all machining centers encounter. Generally, when the machine fails during the tool change process and the collision of the machine tool is found, it is necessary to press the emergency stop or reset.

The tool change point can be selected in any one of the parts, as long as it does not obstruct the tool, chuck, and tailstock workpiece. Change the tool at the nearest point, and take a relatively close point from the part that needs to be machined, which can save processing time. Instructions for changing tools can be prepared in advance.

Typical composition: 1CNC motherboard: used for core control, calculation, storage, servo control, etc. The new motherboard integrates PLC functionality.

Board: Used for peripheral motion control. The PLC board of the new system has been integrated with the CNC motherboard.

Board: Early IO boards were used for the exchange of switching signals between the CNC system and the outside. The new IO board mainly integrates display interface, keyboard interface, handwheel interface, operation panel interface and RS232 interface.

Wait. 4 mmC board: human-machine interface board. This is a PCIZED board and is not required. It comes with a CRT, a standard keyboard, a floppy drive, a mouse, and a memory card.

and serial, parallel interfaces.
