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 (L i , F des ) 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 (L i , F des ) are correspondingly computed as well as by providing a subassembly ( 1 ) wherein the desired drive values (L i , F des ) 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 (X T , Y T , Z T , X m , Y m , Z m , F ix , F iy , F iz ) and transmitting the measurement values (X T , Y T , Z T , X m , Y m , Z m , F ix , F iy , F iz ) to the control computer unit in response to a command therefrom.
