5 kinds of tooth profile errors in gear milling and their reasons

The explanations of the five tooth profile errors of gear milling and their causes are as follows, for reference and understanding.

2. Tooth profile height error and its XNUMX main reasons

1. When the milling cutter sharpens the rake face, there is an error. If the milling cutter has a larger rake angle, the tooth profile height will increase, otherwise it will be shortened.

2. Tooth profile error of milling cutter.

3. Tooth shape asymmetry and its XNUMX main reasons

1. The axial movement of the cutter shaft.

2. The tooth profile of the milling cutter is asymmetrical.

3. When the gear milling machine is adjusted, the position of the milling cutter deviates from the center.

2. Tooth profile error and its XNUMX main reasons

1. Manufacturing error of milling cutter tooth profile.

2. The error between the arc of the milling cutter tooth profile design era and the standard tooth profile curve,Involute gearInevitable errors in tooth milling.

Fourth, the periodic error of the tooth surface and its 3 main reasons

1. Vibration of the workpiece clamping system.

2. Vibration of the tool rest system of the machine tool.

3. Circular runout of milling cutter or cutter shaft.

Five, the appearance of edges and corners of the tooth shape and its 2 main reasons

1. Milling cutter or cutter shaft radial runout or end face runout.

2. Manufacturing error of milling cutter.
