proper break-in is important for the cutting per-
formance and longevity of the blade. during the
break-in period, only mild pressure should be
exerted on the blade (about half of the normal
feed pressure for a properly broken-in blade).
the duration of the break-in period is determined
by the hardness of the material cut. the break-
in period is defined in terms of square inches of
material cut.
—For hard materials, such as steel, the
break-in period is the first 50 square inches
of material cut.
—For soft materials, such as aluminum,
the break-in period is the first 150 square
inches of material cut.
to determine the square inches of a cut, calculate
the area of the cross-section of the workpiece.
Keep in mind when cutting hollow-section pieces
that the area only includes the solid walls of the
workpiece. refer to
figure 7
to calculate approxi-
mate square inches for many typical cuts.
