MILLING MACHINE OPERATIONS - OD1644 - LESSON 1/TASK 2
single-angle milling cutters (figure 29) or double-angle milling cutters.
The single-angle cutter contains side-cutting teeth on the flat side of the
cutter. The angle of the right or left cutter edge is usually 30, 45, or
60. Double-angle cutters have included the angles of 45, 60, and 90.
FIGURE 29.
SINGLE-ANGLE MILLING CUTTERS.
(i)
Concave and Convex Milling Cutters.
Concave and convex milling
cutters (figure 30 on the following page) are formed tooth cutters shaped to
produce concave and convex contours of one-half circle or less. The size of
the cutter is specified by the diameter of the circular form the cutter
produces.
(j)
Corner-rounding Milling Cutter. The corner-rounding milling cutter
(figure 30) is a formed tooth cutter used for milling rounded corners on
workpieces up to and including one-quarter of a circle.
The size of a
cutter is specified by the radius of the circular form the cutter produces,
as with concave and convex cutters.
