Introduction • Five-axis machining has been used in aerospace applications for many years, but it is only recently that the tool making industry has shown similar interest. • The main advantage of five-axis machining is the ability to save time by machining complex shapes in a single setup. • An additional benefit comes from allowing the use of shorter cutters that permit more accurate machining.

Axes • To accommodate machining scenarios involving tools set at an angle or in order to mill geometries located anywhere in space, the three linear axes X, Y and Z are required along with two of the rotary axes A, B or C. • It must be possible to control the axes simultaneously.

CNC Machine Axes of Motion More complex CNC machines have the capability of executing additional rotary motions (4 th and 5 th axes).

Swarf Machining • Swarf machining is a technique that allows side cutting with an endmill while proceeding along the surface of a part, such as the sidewalls of a tapered rib. • A similar toolpath also may be generated from surfaces according to a set of wireframe references. All tool types including tapered tools may be used for swarf machining.
