Checking abnormal problems that occur during 数控车削 and milling can be done from the following aspects:
1. Equipment inspection:
Clean the tool holder and cable cap to ensure that they are clean and free of impurities.
Use a dial gauge to check the runout of the tool holder and tool to ensure that the runout value is within a reasonable range (例如 0.005).
Check whether the fixture design is reasonable. The stability of the fixture is crucial to the processing accuracy.
Check the wear of the machine tool, especially the spindle and the carriage, to see if there is any loss of accuracy due to wear.
Check whether the communication parameter settings of the CNC system and external equipment are consistent, such as baud rate, data bit, stop bit, 等.
2. Programming and processing parameter inspection:
Check whether the programming processing parameters are reasonable, and adjust the processing parameters according to the product material and the rigidity of the machine tool spindle.
Check the code of the processing program to confirm whether the logic and syntax are correct.
Check whether there is product deformation or unstable processing accuracy caused by unreasonable processing parameters.
3. Tool and cutting fluid inspection:
Regularly check the wear of the tool and replace the worn or broken tool in time.
Check whether the tool clamping device is correctly installed and adjusted to ensure that the tool is firmly fixed.
Check whether the supply of cutting fluid is normal, ensure that the cutting fluid is sufficient and has a good cooling and lubrication effect.
4. Processing process and result inspection:
Observe whether the processing process is smooth and whether there is resonance or creeping.
Check whether the size and surface finish of the processed workpiece meet the requirements.
If the taper size head phenomenon occurs, check whether the machine tool is placed horizontally, and whether the tool is let down when turning the long axis due to hard material or deep cutting of the tool.
5. Servo system inspection:
Check the power supply of the servo drive and motor to ensure that the power supply is stable.
Check whether the servo drive parameter settings are correct, such as servo gain, speed loop parameters, 等.
Check whether the encoder connection is loose or damaged, and reconnect or replace it if necessary.
6. Environmental factor inspection:
Check whether the operator’s operation method is correct and whether it is operated in accordance with the specifications.
Check whether the environment around the machine tool is clean, free of debris and dust.
Pay attention to the heat dissipation of the machine tool and ensure that the machine tool runs at normal temperature.
