Part 2, to run in Aerospace Manufacturing and Design's April-May issue, will discuss best practices in titanium machining. The machine fastens to the compound rest of the lathe with a T-slot bolt which fits in the slot of the compound rest in the same manner as the lathe tool post. HOW TO MACHINE TITANIUM Machining titanium requires coated carbide tools that will resist the stickiness of the alloy and break up the long chips. It runs on single-phase, household power, and the lathe comes in a fully-assembled enclosure as part of the base . Tool setting is very important to machine tool processing operations. It is particularly well suited to the temperatures found in Titanium machining, and it adds lubricity to help fight galling and chip welding. Out of the handful of basic cutting tool coating types, TiAlN is clearly the best at maintaining its integrity and properties as the temperature in the cut gets hot. The main thing to choose is the material. If you're focused on removing as much material as possible in the shortest amount of time to achieve high machining efficiencies, the forces generated put a lot of pressure on your machine tool and on your cutting tools.
