Line 3:

For example, the handwheel of a typical CNC control will move any of the slides of the machine by one minimum increment, such as 1 [[micrometre]] or 1 [[thousandth of an inch#Tenths|ten thousandth of an inch]], for each pulse, and the handwheel will give one [[ratchet (device)|ratchet]] click or other [[haptic technology|haptic click]] to confirm to the user that a single increment occurred. Several selector switches control the handwheel's output: one allows each of the machine's axes (X, Y, Z, and so on) to be selected in turn; another shifts through several ranges of output, so that one click of the wheel is either one minimum increment, 10 times that, or 100 times that.

The modern trend in CNC [[user interface design]] is to place the MPG on a handheld [[pendant]] that the operator can carry, making it conveniently independent from the main control panel, just as a [[game controller]] is independent from the [[video game console]].
