A method for manufacturing a ring (i.e. class, championship, or affiliation) begins by receiving order data specifying a series of personalization elements, such as the addition of text and icon designs. A geometric model for each personalization item is constructed. To assemble text panels, the operating system provides font geometry for a desired TrueType font. Then a set of splines are created from the font geometry and are then tessellated to generate polyline sets of data, which are then spaced and mapped between two boundary curves. The personalization elements are then projected onto one of the model's 3D surfaces. A set of machining instructions for a milling machine is generated by obtaining a set of machining pattern strategies, generating a set of curves, projecting the toolpath onto the surface of the ring to calculate the 3D toolpath, and rotating it to a desired angle. |
