CNC machine parts tool setting is a key step in CNC machining, its accuracy and precision directly affect the processing quality and efficiency. In the process of tool setting, need to pay attention to the following points:
First, the preparation before tool setting
Confirm the status of the machine tool:
Before starting the machine, check whether the machine components are normal, to ensure that the machine is in good condition.
Tool and workpiece inspection:
Check whether the tool is suitable for the current machining task, to confirm that the tool is not damaged, moderate wear.
Make sure the workpiece is correctly clamped on the table and the surface of the workpiece is clean and free of impurities.
Machine Zeroing:
Before tool setting, perform machine zero operation to ensure that the machine coordinate system is in the initial state.
Second, the attention of the process of tool setting
Select the appropriate tool setting method:
According to the machine tool, workpiece and tool characteristics, choose the most appropriate method of tool setting. Common tool setting methods include test cutting method, plug ruler tool setting method, edge finder tool setting method, automatic tool setting method, etc..
Maintain a safe distance:
In the process of tool setting, always maintain a safe distance between the tool and the workpiece to avoid collision.
Control feed speed:
During tool setting, the feed speed should be appropriately slowed down to control the tool position more accurately.
Record data accurately:
After the tool setting is completed, accurately record the tool offset, rotation angle and other key data for subsequent machining to call.
Pay attention to tool compensation:
For multi-tool machining tasks, pay attention to tool compensation settings and adjustments to ensure that each tool can accurately reach the intended position.
Third, the verification and adjustment after tool setting
Cutting test:
After the tool setting is completed, carry out cutting test to verify the accuracy of tool setting. Observe whether the machining results are in line with expectations, and make timely adjustments if there is any deviation.
Check the status of the machine tool:
During the cutting test, pay attention to observe whether the running status of the machine tool is smooth, with or without abnormal sound or vibration.
Adjust the tool parameters:
According to the cutting test results and machine status, timely adjustment of tool parameters such as cutting speed, feed rate, etc., in order to obtain the best machining results.
Fourth, other precautions
Keep clean:
During tool setting and machining, keep the machine tool, tool and workpiece clean to avoid impurities affecting machining accuracy and tool life.
Regular calibration:
Regularly calibrate machine tools and measuring tools to ensure their accuracy and stability.
Observe operating procedures:
Strictly comply with the operating procedures and safety norms of CNC machine tools to ensure personal safety and equipment safety.
In summary, CNC machine tool parts to the knife need to pay attention to a number of aspects, including the preparation of the knife, the knife in the process of precautions, the knife after the verification and adjustment, as well as some other details. Only in the process of tool setting to be rigorous and meticulous, excellence, in order to ensure the accuracy and efficiency of CNC machining.
