CORRELATION GEOMETRY-PARAMETERS ON THE DESIGN OF CONSTANT PITCH SPIRAL-TURNED ORNAMENTS

Abstract

Spiral-turned ornaments used in the decoration of furniture requires a special study in terms of their geometry, for correlating the geometrical elements in such a way as to ensure an adequate aesthetic shape, both of the decorated part, as well as of the furniture as a whole. When change a single geometric parameter imposed by the aesthetic execution, a re-correlation of all other parameters occurs, in order to fulfil their geometric dependence. This paper aims to present the possibilities of re-correlating the geometrical parameters from the design phase of the spiral-turned parts, design to be performed based on a well-defined algorithm. The algorithm established in this paper with regard to the design and the re-correlation of the parameters – in case of constant pitch spiral-turned ornaments – ensures the optimal conditions for maintaining the aesthetics of ornament as in the original concept of the product designer. Re-correlation of geometry and parameters is based on an analytical and graphic method, as shown in the paper.
