High Feed Milling Can Reduce Cycle Times 50 Percent

Tungaloy DoFeedThis milling strategy reduces cycle time and tool wear by maintaining high feed rates during aggressive machining passes, even in tough materials like tool steels, titanium and Inconel.

Everyone wants to reduce cycle times, but simply machining faster isn’t necessarily the answer. If high speed milling comes at the cost of reduced tool life and surface finish, the minutes gained could still cost you in the long run. But what if you could remove metal at much higher rates yet actually increase tool life in the bargain? You can with high feed milling.

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. Moreover, the process works especially well in difficult materials, from tool steels to aerospace alloys. 

Here’s more on how it works.
