Fanuc Series Oi-tf Plus Programming Manual
Locks the spindle at a fixed RPM. Essential for drilling and threading.
The 0i-TF Plus includes several "smart" features that were previously reserved for high-end aerospace controllers:
Because lathe inserts have a rounded tip rather than a perfect point, cutting tapers or profiles without compensation causes dimensional inaccuracies.
Moves axes at maximum speed to a target point. Never use for cutting. fanuc series oi-tf plus programming manual
Instead of typing G71 U2.0 R1.0; , the operator inputs part geometry parameters (diameter, length, depth, etc.) into graphical forms. The system then generates the ISO code behind the scenes, making it an ideal resource for job shops and for operators new to CNC turning.
Manual programming can be incredibly time-consuming. The 0i-TF Plus features automated that wrap hundreds of lines of complex roughing geometry into just two simple code blocks. G71: Stock Removal in Turning (Roughing Cycle)

Executes the finish pass after roughing. Threading Cycles:
Left-side tool compensation (used when cutting behind the part centerline or back-boring).

The "Plus" iteration represents FANUC’s evolution in smarter, faster, and more intuitive CNC architecture. It bridges traditional G-code programming with modern digital enhancements, offering improved processing speeds, a more responsive user interface (iHMI), and advanced customization.
