Novel Machining Technique for Surface Patterning by Diamond

This paper presents a novel method of machining image su r-face by diamond turning with fast tool s ervo (FTS) . In the proposed methodology, three -dimensional pixel data [X, Y, Z] are extracted directly from a digital image via MATLAB image processing tool, which are p re-processed and supe r-imposed onto a three -dimensional spiral tool tr ajectory. The prop osed methodology has been experimentally validated by the su ccessful machining of freeform features based on any digital image . The freeform features can be designed in a manner in which is otherwise generated from complex equ a-tions. It allows even a layma n to customize a feature without working out any mathematical equations.
