im not sure if this helps but im going to quote some lines from my book kickin' bot about cutting titanium
quote:
Titanium has the ability to locally work-harden, which means that once the material reaches a certain temperature, it will harden in that spot. in our case, this unfortunatly happens in the exact spot your cutting, as a direct result of the cutting process. As the titanium begins to harden, the blade will have a tougher time with the material, whitch generates even more heat in a visious cycle. it becomes harder and harder to cut, and will end up taking you ten times longer to get through, and probobly several dull blades in the process
whats the solution? Make sure it doesnt heat up. This means cutting at a very low speed with a lot of lubrication. For example, given similarly sized peices of aluminium and titanium, what will take you one minute to cut in aluminium will take you 10 to 15 minutes to cut in titanium
it also recomends further down to use a jig saw, with the lowest speed on and the orbital setting on, and the cutting edge should be constantly flushed with WD-40 to keep it cool
hope this helped
