The very first entry in the glossary has some bugs. You can't rotate something along
an axis; you rotate it around, or about an axis (or, if you prefer, in the plane given by the other two axes). A is rotation around X, B is around Y, C around Z. The entry for the B axis is correct, and contradicts that for the A axis. The C axis entry even has the illustration, and the axis names and directions are correct, including those of the rotational axes.
I would appreciate qualifying the statement that the Z axis is up and down. It's actually the axis parallel to the spindle (main spindle, if more than one; home/default position thereof, if it rotates). Thus, the Z axis of a lathe runs left to right.
Some terms for the missing letters: Inverse time, Microstepping, High-speed machining, Universal motor, (also Stepper motor, Servo, Brushed DC motor, Brushless DC motor -- for completeness), Machine coordinates, Jogging, Open-loop control (also Closed-loop control), Jig (and Fixture), Helix angle, Unipolar (and Bipolar), Homing, Macro, Variable, VFD, NEMA, Hall effect sensor. I'd also add: Trimpot, Coil, Winding. I can't think of any Q except Quiet Cut, which is an Inventables marketing term for a cheap brushed DC spindle and not worthy of the glossary, nor any K.

That's also true for what's already in the glossary...
