1、 Tool related reasons

1. Uneven tool wear or excessive blade wear. This may lead to unstable cutting forces, thereby affecting the dimensional accuracy of the parts. To solve this problem, tools should be replaced or repaired in a timely manner according to the specific situation.

2. The tool is too dull or too large. This may lead to excessive cutting force and unstable phenomena such as vibration or burrs on the surface of the parts. To reduce the occurrence of this situation, appropriate tool parameters should be selected.

2、 Reasons for cutting parameters

1. The cutting speed is too high or too low. If the cutting speed is too high, the part may be twisted or the surface may be rough, while if the cutting speed is too low, it may lead to too long processing time, which in turn affects the yield. Therefore, the cutting speed parameters should be reasonably selected.

2. The feed rate is too fast or too slow. If the feed rate is not set reasonably, it may lead to unstable machining quality, so the feed rate should be adjusted appropriately according to the specific situation.

3、 The reason for the material of the workpiece

1. Uneven hardness. If the hardness of the workpiece is uneven, it will lead to unstable machining quality. The solution to this problem is to adjust the cutting parameters appropriately during the machining process.

2. Uneven surface roughness of the workpiece. If the surface roughness of the workpiece is uneven, unstable phenomena such as surface burrs may occur during processing. The solution to this problem is to improve cutting quality, adjust the process flow appropriately, and improve machining accuracy.

In summary, the unstable size of parts processed by gear hobbing machines may be caused by factors such as tools, cutting parameters, and workpiece materials. The solution to this problem is to adjust various parameters appropriately during the actual processing operation, improve process requirements, and try to avoid these problems as much as possible.
