1. Keep Radial Engagement Low One of the crucial challenges of titanium is heat dissipation. In this metal, relatively little of the heat generated during the machining operation is ejected with the chip. Compared to machining other metals, a larger percentage of the heat in a titanium machining process instead goes into the tool.

We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.

Stubby, ball end mills are typically used to take light cuts at fast feed rates in titanium and stainless parts. Minimizing tool gage length helps maximize stiffness. According to Mr. Snow, light cuts are also less likely to introduce stress into the material, so parts with thin walls won't "pop" out of shape after machining.
