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 programme 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 using an absolute digital measuring device for point-to-point control {the positional error is used to control continuously the servomotor according to its magnitude with a combination of feedback covered by [CPC: G05B19/293] - [CPC: G05B19/296]}
