MILLING MACHINE OPERATIONS - OD1644 - LESSON 1/TASK 1
clamped directly to the milling machine table to simplify handling and
Figure 16 illustrates face milling performed with a swivel cutter
head milling machine with its spindle in a vertical position. The workpiece
is supported parallel to the table in a swivel vise.
Angular surfaces can also be face milled on a swivel cutter head
milling machine. In this case, the workpiece is mounted to the table and
the cutter head is swiveled to bring the end milling cutter perpendicular to
the surface to be produced.
During face milling operations, the workpiece should be fed against
the milling cutter so that the pressure of the cut is downward, thereby
holding the work against the table.
Whenever possible, the edge of the workpiece should be in line with
the center of the cutter.
This position of the workpiece, in relation to
the cutter, will help eliminate slippage.
