Abstract

The article deals with the formation of surfaces by the movement of auxiliary surfaces (intermediaries), based on a parametric kinematic screw. In modern existing mechanisms operating at high speeds, dynamic loads exceed static loads many times over. To improve accuracy, it is necessary that the process of processing a part with a cutting tool is carried out taking into account the coefficient of uneven rotation in the manufacture of products. The technology of processing complex surfaces by the most productive method of running is closely related to the profiling of conjugated curved surfaces formed by the movement of intermediaries. The mating curved surfaces of kinematic pairs, with different parameters, in turn, require the development of effective kinematic methods of formation and ensuring high accuracy in the processing of products used in mechanisms and processed on automatic lines, allowing to expand the scope of the most advanced methods of processing complex products.. Proposed  1 the kinematic screw has proven itself well for the formation of mating ruled surfaces, so the urgent task arose to investigate the possibility of using a kinematic screw for mating curved surfaces. The study was developed on the basis of the proven theorem of Academician A.N. Podkorytov, about instantaneous envelope axoids, which allows you to form mating curved surfaces, using a parametric kinematic screw, which takes into account the kinematics of metal-cutting machines. When solving the set task, the design time is reduced and the accuracy of manufacturing parts in the mechanisms of weapons and military equipment is increased. Keywords: kinematic method, geometric model, cutting tool, mating surfaces, curved surface, parametric kinematic screw, auxiliary surface (intermediaries), instantaneous axoid envelopes.
