Entering the workpiece

A sudden load is applied to the cutter when it enters theDepth Per Pass

There are three ways to initially enter the workpiece: radial entering, tangential entering Number of radial passes by arc, tangential entering by line. Radial entering

The cutter enters the workpiece in a straight line to the center workpiece axis. This is the simplest method, but also the least recommended because the angle of the hugging is too large. Internal Threading
