Abstract

Abstract: Through analyzing mathematical principles of designing the conical curve gauge
(ellipse gauge, hyperbola gauge and parabola gauge), a set of design theory is put forward based
on the optical and geometric properties of conical curve. By applying this theory, a new type of
conical curve gauge is designed, which is composed of multiple simple linkage mechanical parts
assembly, and which can help quickly draw various normative conical curves common in
engineering. It makes up for the disadvantage that the function of general engineering drawing
instrument is single and has a good prospect of application.

Key words: engineering drawing, conic curve, geometrical properties, compasses instrument
