The invention is directed to a coordinate measuring apparatus having drives (14, 23) for moving the components (2, 7) of the apparatus. The drives are displaced in accordance with sets of desired drive values (Li, Fdes) which are sequentially pregiven at a fixed clock frequency. The operation of the control can be integrated into a control computer unit (3, 4, 5) by making available a control computer unit (3, 4, 5) having an operating system without real-time performance in which the desired drive values (Li, Fdes) are correspondingly computed as well as by providing a subassembly (1) wherein the desired drive values (Li, Fdes) can be stored and driven to at subsequent clock pulses in advance in response to a command of the control computer unit (3, 4, 5). The subassembly (1) executes at least one of the following functions: automatically outputting the sets of desired drive values to the plurality of drives at the fixed clock frequency and/or storing the measurement values (XT, YT, ZT, Xm, Ym, Zm, Fix, Fiy, Fiz) and transmitting the measurement values (XT, YT, ZT, Xm, Ym, Zm, Fix, Fiy, Fiz) to the control computer unit in response to a command therefrom.
