28. • EXAMPLE Material-removal Rate, Power, Torque, and
Cutting Time in Slab Milling
• A slab-milling operation is being carried out on a 300-mm-long,
100-mm-wide annealed mild-steel block at a feed f = 0.25
mrn/tooth and a depth of cut d = 3.0 mm. The cutter is D = 50 mm
in diameter, has 20 straight teeth, rotates at N = 100 rpm, and, by
definition, is wider than the block to be machined, Calculate the
material-removal rate, estimate the power and torque required for
this operation, and calculate the cutting time.
• Solution:

32. Cutters
Figure 24.11 Cutters for (a) straddle milling, (b) form
milling, (c) slotting, and (d) slitting with a milling cutter.
a. Straddle: more cutters are
used to machine two parallel
surfaces on the workpiece
b. Form milling produces
curved profiles using cutters
that have specially shaped
teeth
Slotting and slitting operations
are performed with circular
cutters. [T-slot cutters,
