Editor Emeritus, Modern Machine Shop. 3+2 machining is a technique whereby a three-axis milling program is executed with the cutting tool locked in a tilted position using the 5-axis machine's two rotational axes, hence the name, 3+2 machining. It is also called "positional 5-axis machining" because the fourth and fifth axes are used to ...

Maching On A Milling Machine. Most cnc milling machines have the ability to move the spindle along the z-axis which allows for freedom to engrave and make much more complex parts.When a fifth axis is added, making the machine a 5-axis machine, the b axis controls the tilt of the tool to make extremely complicated geometries.

Different Types of Machining Operations. Two primary machining processes are turning and milling – descried below. Other processes sometimes dovetail onto these processes or are performed with standalone equipment. A drill bit, for instance, may be installed on a lathe used for turning or chucked in a drill press.
