The shaping of the complex profile surface of amber cabochons and the kinematic structure of specialized grinding machines

The article deals with the study of the process offorming the complex profile surface of the amber cabochon in order to identify classification criteria for constructing a geometric model, highlighting production lines and based on the frame-kinematic theory of surface formation for the developed geometric model, a kinematic structure of the machine with new properties is proposed. A comparative analysis of the proposed kinematic structure and a Polish-made machine tool is carried out and prospects for its improvement are also evaluated.


Keywords: amber cabochon, basic profile, volumetric model, shaping methods, shaping movements, specialized machine, kinematic structure.
