HOW IT WORKS?

High-Feed Milling Mechanism

First utilized in the Die and Mold industry, High-Feed Milling is a milling method that pairs shallow depth of cut (DOC) with high feed rate up to 0.08" per tooth to maximize the amount of metal being removed from a part, resulting in more parts being machined more quickly.

The HFM mechanism is based on the “chip thinning” effect. Chip thinning depends on the lead angle of a milling cutter. A cutter with a 90° lead angle has no benefit of chip thinning as 0.008" of feed per tooth only delivers the same 0.008" of chip thickness (Fig. 1). In the case of a cutter with a 45° lead angle, a 0.01" of feed per tooth creates a 0.007" of chip thickness (Fig. 2) which allows the feed to be increased, resulting in reduced cycle time. Fig. 3 shows the chip thinning effect of DoFeed, Tungaloy’s best selling HFM line, where a 0.05" of feed per tooth provides chip thickness of only 0.007", and cycle time is typically decreased by 50% or more.

Low cutting force is also an advantage of HFM. The lead angle on a cutter decides the direction of the cutting force. A 90° cutter (Fig. 1) will produce cutting force that acts perpendicular to the spindle, putting incredible pressure on the tool. As for a 45° cutter (Fig. 2), cutting force acts against the spindle at a 45° angle. With DoFeed, cutting force is almost parallel, and directed back to the spindle due to its acute lead angle (Fig. 3), which means less pressure on the spindle.
