how to operate cnc milling machine
1. Turn on the CNC milling machine
· Turn on the machine first, then the system.
2. Return to the reference point
· For CNC milling machine with incremental control systems, this step needs to be performed to establish the coordinate movement reference.
3. Adjust the CNC milling machine processing program
· Input the processing program and select the input method according to the storage medium.
4. Edit the CNC milling machine program
· Edit the input program as needed, including adding, deleting, and changing.
5. Lock the processing program
· Check the program. If there is an error, it needs to be re-edited.
6. Workpiece and tool alignment on the CNC milling machine
· Use manual movement or hand-cranked wheels to move the machine tool and align the workpiece to the start of the program.
7. Start coordinate feeding for continuous processing
· Usually the program in the memory is used for processing, and the feed speed can be adjusted.
8. CNC milling machine operation display
· Use the CRT display to monitor the processing status, including the workbench position, program and machine status.
9. CNC milling machine program output
· After the processing is completed, if the program needs to be saved, it can be output to an external device.
10. CNC milling machine shutdown
· Turn off the machine first, then turn off the system.
Precautions during the operation of CNC milling machine
1. Check whether the lubricating oil, cutting fluid, etc. are sufficient.
2. Pay attention to the moving direction during manual operation to avoid collision.
3. Use G00 instructions as little as possible, especially when multi-axis linkage.
4. When using computer serial port communication, pay attention to the operation sequence.
5. When using the DNC function, pay attention to the memory capacity.
6. When an alarm occurs, find the cause according to the alarm number.
7. When using the edge finder to set the tool, control the tool error.
Detailed steps of tool setting operation X and Y tool setting
1. Clamp the workpiece and leave a position for the edge finder to measure.
2. Move the worktable so that the edge finder contacts the left side of the workpiece.
3. Fine-tune the operation and contact the workpiece until the edge finder lights up.
4. Record the X coordinate value.
5. Similarly, measure the X coordinate value on the right side.
6. Calculate the X coordinate value of the origin W of the workpiece coordinate system in the machine tool coordinate system.
7. Similarly, measure the Y coordinate value of W in the machine tool coordinate system.
Z tool setting
1. Install the machining tool.
2. Place the Z-axis setter.
3. Move the spindle so that the end face of the tool contacts the upper surface of the setter.
4. Fine-tune the operation so that the pointer on the end face of the tool indicates the zero position.
5. Record the Z coordinate value.
6. Calculate the Z coordinate value of W in the machine tool coordinate system.
7. Input the measured X, Y, and Z values into the storage address of the machine tool workpiece coordinate system.
Precautions for CNC milling machine
1. Use the correct tool setting tool.
2. Control the fine-tuning feed amount to improve accuracy.
3. Operate carefully to avoid collision.
4. Save the tool setting data correctly.
Input and modification of tool compensation values for CNC milling machine
1. Input the compensation value according to the tool size and position.
2. Pay attention to the correctness, symbol and address of the compensation data.
