A(n) ____ motor is a hybrid electric motor with half motor/half position sensor.

A(n) ____ assembly device consists of a screw and nut assembly with steel balls in place of threads.

Some drawings, called ____, look like solid illustrations of the actual part and are much more realistic looking.

A ____ is an auxiliary secondary spindle, which opposes the machine's main headstock spindle.

____ mode provides a blank program screen for entering short programs or single program commands.

____ cycles require the programmer to write a block or two of code in a specified format.

When a CNC lathe is equipped with an automatic tool changer it is called a ____.
