Starting from production practice, this article summarizes common problems and improvement methods in CNC machining process, as well as how to choose the three important factors of speed, feed rate, and cutting depth in different application categories for your reference. Article from reference official account: [machining center]
1. Depth Z-axis tool alignment error.
2. Errors in the number of hits and operations during the division (such as unilateral data retrieval without feed radius, etc.).
3. Use the wrong tool (such as using D4 tool to process with D10 tool).
4. The program went wrong (e.g. A7. NC went to A9. NC).
5. During manual operation, the handwheel swings in the wrong direction.
6. When manually rapid feeding, press the wrong direction (such as – X and+X).
1. It is important to pay attention to the position of the depth Z-axis tool alignment. (Bottom, top, analytical surface, etc.).
2. Repeated checks should be carried out after the completion of the middle point collision and operation.
3. When clamping the tool, it is necessary to repeatedly compare and check with the program sheet and program before installing it.
4. The program should be executed in sequence one by one.
5. When using manual operation, the operator should enhance their proficiency in machine tool operation.
The interrelationship between the three factors of speed, feed rate, and cutting depth is the most important factor determining the cutting effect. Inappropriate feed rate and speed often lead to reduced production, poor workpiece quality, and significant tool damage.
