Control Mechanisms of Additive Shaping Error with the Use of Hybrid Design Devices

Purpose of research. The study is aimed at improving the accuracy of shaping the surface layer of mechanical engineering products by additive methods.

Methods. Shaping of parts surfaces by additive methods is characterized by high values of shaping error (approximation.)To reduce this error it is necessary to ensure the orientation of the surface at which the normal at the point of the surface being shaped will coincide with the axis of the final link of the shape-generating system. To ensure the orientation of the surface being shaped, the use of equipment for additive shaping with a hybrid design is proposed.

Results.The model of shape-generating system of the equipment for additive shaping with hybrid design has been developed. The problem of parametric synthesis of hybrid design technological equipment for additive shaping has been solved, as a result of which the necessary shaping capabilities of the equipment have been provided. The calculation method of kinematic error of additive shaping has been developed, which allows you to choose such engine and driver of additive equipment that wiil make it possible to obtain the necessary accuracy of shaping.

Conclusion.The developed technique allows us to solve the problem of parametric synthesis of hybrid design technological equipment based on the condition of providing a given value of the kinematic component of additive shaping error.
