Identify material being cut.
Select from tool group catagory description or
the tool group letter from "Pictorial Index" or
following table's header.
Choose surface feet per minute from the speed
range provided in the following table. Start at
middle of range shown for average material
hardness. Lower speed for harder materials
or dry cutting. Increase speed when using
TiAlN coating ( plus 20% SFM x equal IPR ) or
high pressure coolant.
Choose feed curve number. Use higher feed curve
for softer continuously chipping material. Add
feed withdrawls as needed to lubricate cutting
edges and clear chips on deeper holes.
For inch per minute penetration rate see
"PenertrationRate Table".
Exact revolutions per minute are calculated using
formula located below table.
Exact inch per revolution feed see feed curve -
feed multiplier (FM*) table.
