The submitted contribution deals with the identification of texture of metal surfaces produced by the abrasive waterjet with the aim to increase surface quality. To the measurement of surface irregularities, a developed contactless shadow method was applied. A dimensionless statistical parameter CRa for experimentally tested metal materials has been derived the discrete value of which will contribute, in the automated on-line system of feedback, to the optimization of traverse speed of the cutting head, i.e. that technological factor which influences the quality of machined surfaces most.
