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.
Surface integrity is important to improve the fatigue property of components. Proper selection of the cutting parameters is extremely important in ensuring high surface integrity.

Milling titanium is like milling other hardtomachine metals in that a small increase in cutting speed can lead to a big increase in edge wear. Milling titanium is different from other metals because of the risk of heat buildup. Thanks to the metal's low thermal conductivity, overly aggressive milling may even pose a risk of combustion.
