MOBILE CAM MECHANISMS SYNTHESIS USING THE CHARACTERISTIC POINTS. PART I: – THEORETICAL NOTIONS AND CALCULATION ALGORITHMS
The paper is structured in two parts. In the first part, the one in discussion, simple and complex mobile cam mechanisms are presented, as well as their domain of usage. The paper highlights the advantages of graphical methods and suggests the usage of characteristic points in solving the synthesis problems of mobile cam mechanisms, with the assistance of a CAD software. The considerable number of graphical constructions are made with AutoCAD with the help of AutoLisp functions. A calculation algorithm and an AutoLisp function are proposed, which will be used in the second part of the paper, in three applications, to obtain the cams of simple mechanisms and the complex mobile cam mechanisms.
Key words: Mechanism, cam, follower, synthesis, characteristic points, function, AutoLisp, AutoCAD.
