THREAD MILLING TOOLS Depth per pass USER GUIDE Entering the workpiece A sudden load is applied to the cutter when it enters the Depth Per Pass workpiece and as a result the cutter may be broken, or a Based on the number of passes, the table below mark will remain. If entering is smooth, then the load on presents ISCAR's recommendations for depth per the tool will increase gradually and the surface will remain pass, which is expressed as a percentage according “clean”. to the total depth that is required to be removed. 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.
