Description - Massachusetts Institute of Technology

Climb vs. Conventional Milling. When milling, one should be aware of the difference between conventional,and climb milling. In conventional milling, the workpiece is fed into the rotation of the cutter. This type of cut requires lower forces and is preferred for roughing cuts. In climb milling, the work moves with the rotation of the cutter.

High Feed Milling Can Reduce Cycle Times 50 Percent ...

Mar 28, 2019· High-feed milling (HFM) is a process that pairs a shallow depth of cut (DOC) with high feed rates, large stepovers, and modest spindle speeds to maximize the amount of metal being removed from a workpiece. It’s particularly adept at roughing large workpieces and deep pockets where cycle times can be cut in half compared to conventional milling.

Milling | Article about milling by The Free Dictionary

There are two possible milling formats—against the feed (up, or conventional, milling), in which the velocity vectors of cutting and feed are opposite at the lowest point of contact between the cutter and workpiece (Figure 2,a), and with the feed (down, or climb, milling), in which the vectors coincide (Figure 2,b); a max is the maximum ...
