One of the largest advances in TI has been the tooling available to work it. It has become more of a mainstream material, much of that has come from shops having the access to the tooling to make parts out of it. TI on a manual machine is a royal pain, if you dwell on a spot you harden it to the point where your high dollar carbide tool is screaming for mercy while the TI laughs at is until it turns to bubble gum and chucks the tool across the shop. So many shops do not even have manual machines in the shop any longer. CNC makes TI work much easier, and creating toolpaths in the CAM programs have the options for TI also. It is no longer the voodoo unicorn material any longer. I almost bought a Pierce TI action and was going to get every ti part to go with it. But decided on the Mausingfield instead.
