Abstract
The proposal relates to a process and a device for the measurement of the movement path of a point moving in three degrees of freedom by means of simple adaptation possibilities and low technical effort, in which three position encoders (''1'', ''2'', ''3''), each being a mass embodiment are arranged at spacings of d<-1, d<-2, d<-3, whereby in this basic arrangement, the distances d<-1, d<-2, d<-3 of the position encoders (''1'', ''2'', ''3'') are measured by the cyclical connection of the mass embodiments by each adjacent encoder, and then the mass embodiments are coupled to the moved points (4) and (5) or (P) and the lengths of the mass embodiments are recorded and evaluated at preselectable time intervals in order to determine the movement path.
