10 Tips for Titanium : Modern Machine Shop

Dec 13, 2013 · "Climb milling" is the familiar term for this idea. That is, do not feed the milling cutter so that the edge moves through the material in the same direction that the tool is feeding. Known as "conventional milling," this approach to machining causes the chip to start thin and become thicker.

Milling (machining) - Wikipedia

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
