We recently completed our first CNC retrofit of a Gear Hob. The machine is used to produce spline gears of varying nature.

Remove the obsolete electronics
Since we didn't know if the synching problem was caused by the old CNC or the servo drives; we replaced both .
This gave us the added advantge of running our axes in pure digital mode; which is much more responsive.

Running Test Gears
After the installation was complete, we ran performance tests: Hobbing a Straight Spline gear, Taper gear, Crown gear, Helical gear, and 2 different diameter splines on the same shaft. Then we switched to Milling mode, and demonstrated a spline created using a milling cutter.
And as a final test, we homed the X & Y & Z axis, put blue dye on our previously hobbed gear, set the offset on X to -.001" and re-cut the same spline.
