Faster The remarkable progress made in the area of

rough milling in the 1990’s saw the introduction
of fast feed (FF) and high feed milling (HFM).

& Much These highly efficient methodologies overturned
established views and brought radical new ideas
to the field.

Faster Rather than use the traditional high metal removal
technique – milling with considerable depths
and widths of cut – users of the new approach
continued to machine with similar width of
cuts, although they used a much smaller depth
of cut and applied much faster speeds with
substantially increased feed per tooth.

Milling with a large axial depth of cut (DOC)
requires the kind of cutting force provided
by high-power machine tools, whereas FF
roughing with shallow DOC needs a lot
less machine power, although the cutting
tool should run fast. Therefore, light-duty
machines featuring axis drives with sufficient
velocity are sufficient for FF milling.

Energy saving shallow-cut “fast” technology
provides an excellent alternative to power
consuming deep-cut methods. Impressive high
NEW metal removal rates (MRR) at reduced power
input is not the only advantage of the strategy, FF
milling delivers two additional benefits. Shallow
DOC enables contours to be produced that
are very close to the final required shape of a
machined surface, reducing or even eliminating
semi-finish passes. In addition, the small cutting
edge angles of FF milling cutters
