Effect of speed: Generally, higher cutting speeds are used for honing met-
als that shear easily such as cast iron and nonferrous materials. The hon-
ing speed should be decreased when the contact area between grains and
the bore increases. Higher speeds produce ne surface nish and raise the
removal rate (Figure 9.10). It decreases the dimensional accuracy, overheats
the workpiece, and dulls the abrasives. Table 9.2 shows the rotary and recip-
rocating speeds of honing some engineering materials. An increase in that
speed improves the self-dressing characteristics of the abrasive sticks, which
improves the materia ...
