CNC machine tool parts processing steps mainly include the following links:
First, boot and preparation
Boot and return to zero
Start the CNC machine to ensure that all systems are running properly.
Manually return to the machine reference point and establish the machine coordinate system to provide a reference for subsequent machining.
Program input and simulation
The machining program is entered into the CNC(computer numerical control) memory.
Simulate the running of the program, check and modify the error or unreasonable in the program to ensure the correctness of the program.
Second, workpiece clamping and positioning
Job clamping
Clean the surface of the piece to ensure that there is no oil, iron filings and other impurities.
The workpiece is mounted on the machine with the appropriate fixture to ensure accurate positioning and reliable clamping of the workpiece.
Workpiece coordinate system determination
According to the workpiece drawing and machining requirements, determine the workpiece coordinate system.
The workpiece coordinate system is set on the machine to provide accurate position reference for subsequent machining.
Third, tool preparation and tool matching
Tool selection and installation
Select the right tool according to machining requirements and workpiece material.
Install the tool on the spindle of the machine tool and make the necessary adjustments.
Tool setting
Use the tool to set the tool and determine the exact position of the tool in the workpiece coordinate system.
Input tool data, including tool length, radius and other parameters, to ensure machining accuracy.
Fourth, program debugging and trial run
Program debugging
The program is further debugged on the machine to ensure that the program matches the machine.
Adjust cutting parameters, feed speed and other processing conditions as needed.
Trial run
Test run the program in the automatic mode to observe whether the machining process is smooth and whether the cutting quality meets the requirements.
If the problem is found, stop the machine in time to check and modify the procedure or adjust the processing conditions.
Fifth, formal processing
Start machining
After confirming that everything is ready, start the process.
Monitor the machining process to ensure proper operation of machine tools and tools.
Process monitoring
In the process of machining, pay attention to observe the tool wear, cutting force changes and other parameters.
If any abnormal situation is found, it should be stopped immediately for inspection and processing.
Sixth, processing and testing
Completion of processing
When the program is finished, the machine will automatically stop processing.
Turn off the machine power and remove the finished parts.
Quality inspection
Quality inspection of the finished parts, including dimensional accuracy, shape accuracy, surface roughness and other indicators.
If quality problems are found, the reasons should be analyzed and corresponding measures should be taken to improve.
Seventh, cleaning and maintenance
Clean up the scene
Clean the table, jig, tool and other parts of the iron filings, oil and other debris.
Keep the processing site clean and orderly.
Machine maintenance
Perform necessary maintenance work on the machine, such as cleaning and lubrication, fastening screws, etc.
Ensure that the machine is in good working condition for a long time.
To sum up, the steps of CNC machine tool parts processing are a systematic and fine process, which requires operators to operate in strict accordance with the process to ensure processing quality and efficiency.
