spindle and one or more arbor supports.

Operation.
For plain milling, the workpiece is generally clamped
directly to the table or supported in a vise.
The milling machine table
should be checked for alignment before starting to make a cut.
If the
workpiece surface that is to be milled is at an angle to the base plane of
the piece, the workpiece should be mounted in a universal vise or an
adjustable angle plate. The holding device should be adjusted so that the
workpiece surface is parallel to the table of the milling machine.
(a)
For plain milling operations, a plain milling cutter should be used.
Deeper cuts may generally be taken when narrow cutters are used than with
wide cutters. The choice of milling cutters should be based on the size of
the workpiece.
If a wide area is to be milled, fewer traverses will be
required using a wide cut.
(b)
A typical setup for plain milling is illustrated in figure 13 on
page 37. Note, the milling cutter is positioned on the arbor with sleeves
so that it is as close as possible to the
