Therefore, it should be used whenever possible. However, in the case of some hardened materials, or when milling certain difficult-to-machine exotic materials, conventional milling may be preferred. Methods of External Thread Milling right-hand thread......

TMS • Thread Milling System Application and Technical Information Minimum Bore Diameters for Thread Milling Cutting Data Recommendation All thread milling Inserts are full profile or cresting type. Inserts are designed to mill full thread depth In one revolution or pass. When machining difficult materials, two passes may be desired. A 60% thread depth on the first pass and a 40% thread depth on the second pass Is recommended. Thread relief grooves In blind holes are not necessary. Thread milling large parts requires considerably less horsepower compared to other threading methods. Thread...

TMS • Thread Milling System Application and Technical Information ■ Understanding Thread Milling In order to perform a thread milling operation, a milling machine with 3-axis control, capable of helical interpolation, Is required. Helical interpolation Is a CNC function producing tool movement along a helical path. This helical travel combines circular movement In one plane with a simultaneous linear motion in a plane perpendicular to the first. For example, the path from point A to point B (Figure A) on the envelope of the cylinder combines a circular movement in the X and Y plane with a...
