The method of virtual localization of complex shape parts when making them from workpieces with a near to shape of the parts, based on the combination of 3D scanning data of workpieces and CAD model parts. A method of preliminary scheduling of feedrate has been proposed and experimentally tested, which has no restrictions on the number of analyzed CNC blocks and the time of scheduling. The use of a simplified three-interval model of the S-shaped feed profile with a smoothly limited jerk using the sin2 function when planning a contour feed is proposed. An experimental study of the cutting parameters for the effect of sticking the machined material on the tool for the alloy 1933. A method of adapting the cutting modes to variation in the contour feed on curved sections of the machining trajectory. Software for visualization and analysis of experimental data for the study of processes in modern technological systems and robotic systems with CNC based on PC, which provides a large amount of data in the process of real-time equipment management in the amount of several hundred parameters. The analysis of the influence of machining modes on the characteristics of thin-sheet composite materials is carried out. A mathematical model for calculating the parameters of oxygen-air mixture formation in the Ventura CPAP apparatus is proposed to take into account the influence of the accuracy of manufacturing control valve parts on the component composition and mixture consumption. To verify the results of numerical simulation based on the recommendations of the company-developer of the CPAP Ventura, a research stand has been designed that can be used for both production tests and experimental studies of mixture formation in CPAP-type apparatus.
