METHOD OF DECORATING AN OBJECT HAVING A FLAT SURFACE AND OBJECT DECORATED IN THIS WAY

摘要

The invention relates to a method of decorating a timepiece having at least one flat surface, comprising the following steps: fixing the object to an object holder, the surface being situated in a plane XY normal to an axis Z intersecting the surface at a point O₂; turning a cutting tool about an axis C forming an angle aX with the Z axis in the ZX plane; and machining the surface with the cutting tool by relative movement between the object holder and the tool, the movement being a combination of translation on the X axis at a speed of advance v, and rotation about the Z axis at an angular speed ?, v and ? being continuous functions of the time t, in such a way as to produce a spiral pattern in a single pass of the cutting tool.
