The parameter adjustment of CNC punching machine is an important and meticulous process. The following are the basic steps and key points of parameter adjustment, which are expressed and summarized in points in combination with the relevant numbers and information in the reference article:
I. Preparation
1. **Power-on self-check**: First, make sure that the CNC punching machine is in normal operation. After starting up, check whether all parts of the machine are working normally.
2. **Backup data**: Before modifying the parameters, be sure to back up the original data to prevent the loss of modified data. This is a very critical step to avoid data unrecoverable due to misoperation.
3. **Understand the parameters**: Before modifying the parameters, you should have a deep understanding of the parameters to be modified and their impact on the machine. This includes but is not limited to parameters such as processing speed, stroke limit, workpiece thickness, and number of punchings.
II. Parameter modification steps
1. **Enter the parameter modification interface**: Turn on the CNC punching machine and enter the CNC system interface. Find the “Parameter” menu on the control panel and click to enter the parameter modification interface.
2. **Select the parameters to be modified**: In the parameter modification interface, find the parameters to be modified and select them. For example, if you want to adjust the processing speed, you need to select the parameter “Processing Speed”.
3. **Modify parameter value**: According to actual needs, modify the value of the parameter to be modified to the required value. Taking processing speed as an example, if you want to increase the processing speed from the default 200mm/s to 250mm/s, you need to modify the value of “Processing Speed” to 250. Note that before modifying the parameter value, you should make sure that the data has been backed up.
4. **Save changes**: After the modification is completed, save the modified parameters and confirm whether the save is successful. Usually, the CNC system will prompt “Save Successfully” or similar confirmation information.
5. **Test effect**: After modifying the parameters, you need to test the machine to confirm whether the modification is effective. You can select a typical workpiece for processing test to observe whether the processing effect meets expectations.
III. Common parameters and their functions
1. **Processing speed**: The processing speed is the speed at which the CNC punching machine performs the punching operation, usually in mm/s. It needs to be adjusted according to factors such as the material and thickness of the workpiece. For example, for harder materials or thicker workpieces, the processing speed may need to be reduced to ensure processing quality.
2. **Stroke limit**: The stroke limit is the maximum range limit of the CNC punching machine stroke, which is usually adjusted according to the shape, size and other factors of the workpiece. Setting a reasonable stroke limit can prevent the machine from exceeding the safety range during processing.
3. **Workpiece thickness**: The workpiece thickness is the thickness range of the workpiece processed by the CNC punching machine, which needs to be adjusted according to the actual thickness of the workpiece processed. Reasonable workpiece thickness setting can ensure that the machine will not be damaged during processing due to excessive thickness or thinness of the workpiece.
4. **Number of punching**: The number of punching is the number of cycles when the CNC punching machine is operated, which needs to be adjusted according to the shape, quantity and other factors of the workpiece. Setting the appropriate number of punching can improve processing efficiency and reduce machine wear.
IV. Precautions
1. **Safety first**: When modifying parameters, be sure to ensure safety. It is very important to turn off the relevant power switch and follow the safety operating procedures.
2. **Professional operation**: The operator should be professionally trained and proficient in the operation and maintenance methods of the CNC punching machine. Untrained personnel are not allowed to operate the machine or modify parameters at will.
3. **Modify with caution**: When modifying parameters, be careful. Do not modify parameters that you do not understand or adjust beyond the range allowed by the machine. Any improper modification may cause machine failure or safety accidents.
