Finishing A Pocket Floor In Titanium
Machining animation from Boeing illustrates effective techniques for titanium workpieces. This simulation also shows finishing of the floor of the pocket.
Like the previous simulation in this series, this machining simulation provided by Boeing Research and Technology (using CGTech software) shows roughing followed by material removal from the corners prior to finishing. The finishing of the walls is performed with fast passes at successive layers.
This simulation also shows finishing of the floor of the pocket. Note how the tool radiates out from the center of the pocket to the wall. This keeps unmachined stock always adjacent to the cut for support. No section of the floor is ever touched again after it has been machined once.

Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
