Abstract

A conicographic mechanism of I. I. Artobolevski is studied structurally and kinematically (positions). The mechanism is R-RPP-RPR-PRP type. The positions of the mechanism are calculated by the closed-loop method. It is found that the mechanism can draw ellipses, parabolas and hyperbolas. Considerations are made regarding the geometric-kinematic synthesis of the mechanism and the type of the generated curve. Some dimensions of the mechanism were then modified to obtain other types of curves, not conical, curves with several branches, some with closed loops.
