Feed Rate for 3/4 TPI blade:
1.8 in/min (45mm/min)
Feed Rate for 4/6 TPI blade:
1.8 in/min X .70 =
1.3in/min
(reduced by finer than optimum blade pitch factor) (45mm/min x .70= 31.5mm/min)

If the saw is fitted with a blade coarser than optimum (e.g.. 1.4/2.5 TPI) we can still use the graph,
but we go to the 1.4/2.5 curve. As a result we find that the FEED RATE is decreased to 1.3 in/min
(133mm/min) for this blade. If however, the machine is fitted with a finer than optimum blade (e.g.. 3/4
TPI) we use the graph for the optimum blade as before, and then use a multiplier given by the table below.
NOTE: Use the following chart when cutting solids. For structurals, see "CUTTING STRUCTURALS"
in STEP 2.
