Description

 The aim of the investigation is to develop a method for assigning modes of high-speed adaptive CNC machining of aircraft parts with easily deformable elements based on the method of virtual localization taking into account deformation and vibration under the action of cutting forces and its adaptation for use in the manufacturing of precision medical equipment. It was established that the replacement of real elastic support conditions with idealized ones can lead to significant errors in the determination of displacements and natural oscillation frequencies. A method of determining the necessary discreteness of the position and the resolution of the differential characteristics when setting and measuring the parameters of movement along the processing trajectory in the CNC system is proposed. The set of parameters necessary for the specification of the movement in the area of the approach of the tool to the size of processing, taking into account the limitation of the amount of data transmitted to the controller module in the CNC system, is defined. The possibility of combining the control schemes of complex technological systems and registering the necessary number of parameters for the study of control processes is considered. It is proposed to use a software-hardware complex on the PC basis to solve the problem of researching the process of controlling the coupled axes. A method of organizing the interaction of control of coupled axes in the considered complex is proposed, which provides the possibility of implementing various schemes of coupled control and their combinations. A study of the reduction in strength of a thin-walled composite part, weakened by delamination, depending on individual parameters of the defect, its own characteristics of the structure and external loads (mechanical processing) was carried out. A research and industrial stand for testing CPAP ventilators UCL Ventura was developed and manufactured.
