This paper discusses ensuring the specified accuracy and quality of processing parts of various shapes by scientifically validatedchoiceof the processing zone, cutting modes, and making adjustments to the control systems of the technological system for waterjet cutting. In the course of experimental studies, the stiffness of the positioning system for the installation of awaterjet cutting tool, the accuracyand quality of processing with waterjet cutting were determined. The influenceof the stiffness of the positioning system of the abra-sive waterjet cuttingtool on the accuracyand quality of the surface of the ob-tained products and the ways to improve accuracy were determined. Based on the results of the study, recommendations to improve the accuracy and quality of partsare given.
