a. General . The lathe is a machine tool used principally for shaping articles of metal, wood, or other material. All lathes, except the vertical turret type, have one thing in common for all usual machining operations; the workpiece is held and rotated around a horizontal axis while being formed to size and shape by a cutting tool.

• Milling machines are very versatile. They are usually used to machine flat surfaces, but can also produce irregular surfaces. They can also be used to drill, bore, cut gears, and produce slots. • The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head.
ECCNs 2B001.b.2 and 2B001.c.2 cover this group of machine tools, namely mills, grinders, mill/turns, and machining centers. These machine tools are used in a variety of both commercial and military manufacturing processes to cut, grind, …
The contact plate on the drawing is to be produced on a CNC vertical milling machine from a blank of AlMg1 dimensioned 100 x 100 x 25 mm.

BANDSAW MACHINES Metal-cutting bandsaw machines fall into two basic categories: vertical machines (Figure 6-2) and horizontal machines (Figure 6-3). Band saws use a continuous saw blade. Chip removal is rapid, because each tooth is a precision cutting tool and accuracy can be held to close tolerances eliminating or minimizing many secondary ...
MACHINE Milling is the process of machining flat, curved, or irregular surfaces by feeding the workpiece against a rotating cutter containing a number of cutting edges. The usual Mill consists basically of a motor driven spindle, which mounts and revolves the milling

DOC has less effect on tool wear than speed and feed, however speed should reduced in deep cuts. With end mills the rule of thumb is the depth of cut should be limited to 1/2 the diameter of the end mill. DOC also depends on the rigidity of the machine, the method of workholding, power of the machine, etc.
