MILLING MACHINE OPERATIONS - OD1644 - LESSON 1/TASK 1
FIGURE 15.
ANGULAR MILLING.
(2)
Operation. Face milling cutters, end milling cutters (figure 16 on
the following page), and side milling cutters are used for face milling
operations.
The size and nature of the workpiece determines the type and
size of the cutter required.
(a)
In face milling, the teeth on the periphery of the cutter do
practically all of the cutting.
However, when the cutter is properly
ground, the face teeth actually remove a small amount of stock which is left
as a result of the springing of the workpiece or cutter, thereby producing a
finer finish.
(b)
It is important in face milling to have the cutter securely mounted
and to see that all end play or sloppiness in the machine spindle is
eliminated.
(c)
When face milling, the workpiece may be clamped to the table or
angle plate, or supported in a vise, fixture, or jig.
(d)
Large surfaces are
generally face milled

a vertical
milling
machine with the workpiece
