Milling

Researchers using computer simulation and refined probing techniques attempted to mill a pocket as accurately as possible. This report tells how the researchers used their high-tech tools and how close to perfection they came.

The benefits of TiN and TiCN coatings are list in high-temperature applications such as the machining of exotic metals. TiAlN coatings, on the other hand, perform better at higher temperatures. This article describes the properties of TiAlN that make it the coating to use with high-temperature work.

Modern control technology makes extremely fast milling speeds possible. But the top speed can only be as fast as the slowest link in the chain between controller and machine. This article looks at some of the bottlenecks that can prevent a mill from running at full speed.

When shops crank up the speed, they have to be prepared for the consequences, even if they're milling "easy-to-machine" aluminum.

Tunable tools can be adjusted to dampen vibration. However, shops must have the right equipment to tune them quickly and precisely. This article describes an instrument that can provide the necessary feedback. A system that uses a mill's vibration frequency to sense problems with the tool is also described.
