A thread programming method that is ignored by the public. Although the method is simple, its effect is not simple. It has the following advantages:
1. Reduce the winding of iron filings on the workpiece, thereby improving the surface quality of the part
2. It improves the thread surface quality and controls vibration
3. It can increase the cutting speed, mainly used for turning of slender dry threads, thereby improving productivity
This method is:
A method for achieving chip control in thread turning applications by ramping in and out of the toolpath to thread in segments.
