Open loop systems, e.g. using stepping motor

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Program-control systems > electric > Numerical control [NC], i.e. automatically operating machines, in particular machine tools, e.g. in a manufacturing environment, so as to execute positioning, movement or co-ordinated operations by means of program data in numerical form > characterised by positioning or contouring control systems, e.g. to control position from one programmed point to another or to control movement along a programmed continuous path > Open loop systems, e.g. using stepping motor

CPC:

Program-control systems > electric > Numerical control [NC], i.e. automatically operating machines, in particular machine tools, e.g. in a manufacturing environment, so as to execute positioning, movement or co-ordinated operations by means of program data in numerical form (G05B19/418 takes precedence) > characterised by positioning or contouring control systems, e.g. to control position from one programmed point to another or to control movement along a programmed continuous path > Open loop systems, e.g. using stepping motor

No child classifications to compare. This is a leaf node in both IPC and CPC.
