The threads of spindle encoder.！

Threads are continuous protrusions and grooves formed on a cylindrical or conical surface along a helix with the same cross-sectional shape. The threads formed on the cylindrical surface are called cylindrical threads, and the threads formed on the conical surface are called taper threads. The threads formed on the outer surface of the rotating body are called male threads, and the threads formed on the inner surface of the rotating body are internally threaded.
There are many ways to thread the thread. When the thread is applied to the lathe, the lathe clamps the cylindrical workpiece through the three-jaw chuck and drives it to rotate at constant speed. The lathe feed mechanism drives the turning tool (standard thread turning tool) Axis direction for constant linear motion, the tool tip in the workpiece surface cutting triangular groove to form a triangular thread.
Thread processing with track start point (A point, that is, the infeed point) and the end of the track (B point, that is, retreat point). In the thread processing trajectory to ensure that the thread processing is set to have enough speed into the feed section δ and the speed retraction section δ ', to eliminate the servo lag caused by the pitch error
